Replacement Tires

[dutch]

Time for me to replace my tires on my 5th wheel. I presently have the Goodyears G614 RST 235/85r16. I was looking to replace them with Hercules H901. Has anyone here used this tire

[Cummins12V98]

How have the GY's held up for you? How many years old are they?

Hercules are a Chinese made tire.

Hercules are a Chinese made tire.

I have had them on for almost 8 years and this set did fine. I did have a blow out on my first set but Goodyear paid for a new tire and damage to the fiver.

I was told by the tire dealer that these tires are made in Ohio. I guess thats not true. I can get a new set of Goodyear G614 from simple tire for about 1200 but I can't find anyone here to put them on for me. :(

[Notanlines]

Dutch, I'm sure you're wanting to go with the $600 rather than the $1,200 to stay on the cheap side. Dump that Hercules idea and go with the Sailuns instead. It is a less expensive, tried and true tire. Hercules is just a cheap tire.

Any commercial tire shop can do the install.

Sailun have had good reviews. I like to keep my money here if possible! GY will back up their tires. 8 years, I would buy the same!

[Xflyhighx]

Had 3 out of 4 Hercules tires this week that the cords separated. Go with Sailun and you will never look back.

[Tile Guy]

I had 16" Geo tires on my 2009 MS 32TK3 and were only a 1/2 year old when I bought it in June of '18. I am sure the dealer bought the cheapest tires possible and put them on before I bought. This past winter I upgraded to 17.5 wheels and Sailun tires and couldn't be more pleased with them. 1.5 months after I put them on we went on a Utah 5 Natl. Park trip 3300 mi. On our last leg of the trip I noticed that I had picked up a pretty large nail but I had to still drive another 2 hours on the Calif freeway before I could have the tire fixed. Whew made me nervous cause the 5th wheel we had before this one a Carriage Cameo blew a tire on a trip and ended up totaling the rig. So I learned the hard truth about RV tires with that one. We were not able to change the tire due to I forgot to reinstall the spare tire under the trailer before we left on the trip. America's tires fixed it for free. I bought the tires and wheels at trailertiresandwheels.com. $1750 delivered and they came all mounted and balanced.

They have a stellar record!!!

The "G" and "H" GY tires are solid also.

[wingnut60]

Yes, G and H are solid tires until the tread separates...

[Cummins12V98]

Yes, G and H are solid tires until the tread separates...


On the "G" tires they had issues early 07 and prior but they have resolved this issues and are a solid tire since.

The "H" tires date code sometime 15 they had some with tread separation, I had one and they replaced all my tires. Since they have been perfect.

The "E" tires on the market for 2 yrs and 8 months have zero issues.

In the MANY thousands of miles with GY tires I have had ONE tread separation that's it!, not even a flat.

Bottom line they stand behind their tires. More money than the Sailun, yep but I like my money to stay here as much as possible.

[wingnut60]

When mentions of GY blowouts/tread separations stop showing up on the forums, I will believe they have "resolved the issues"....

[Joezilla948]

I am right there with you Joe. I'm looking for new tires for my Atlanta in the next 6 months or so. I do not believe that I will replace the GY 114's with the same. I'm thinking about Saliuns or Coopers.

Joe

[wingnut60]

In a quick search on the SimpleTire.com site, here are current prices:

Cooper $239------ set of 4 $956
Sailun 209------ 836
Hankook 256------ 1024
G-114 347------ 1388

Used to be over $400 for the G-114s. The above prices put GY in better position than before, but I still would not buy them just for the damage coverage. I have no idea what the retail pricing would be on these, and mounting has to be added.
I had a set of 4 Cooper RM170s in the 235 size (6005lb capacity) for under $1000 mounted/balanced at Premier Tire in Livingston, TX, last November. I honestly believe I will never have a blowout/tread separation on one of these tires, but it could happen.
And, also, I think DRV is pushing the envelope on the 2-axle 21k models equipping them with the 215 G-114s--should be the 235s. I used to think 4805lbs/tire was sufficient--lasted very well on my '05 for many, many miles. But now the gross weight has climbed, yet the tires stay the same. Doesn't make sense to me.
Completely different circumstance on the triple-axle models.

[Joezilla948]

Yep, 6 new tires adds a bit to the totals you show. Our GY 114 tires are well into their 4th year on our rig. That's why I am getting somewhat antsy to get them replaced soon.

Did you order your Cooper tires from Simple Tire or did the tire shop in Livingston have them in stock?

Joe

[porthole]

Having had a G-114 blowout on my previous trailer and good experience with GY covering 100% of the claim, I would lean that direction for replacement.

But, that trailer was 4-5000 pounds lighter and had plenty of reserve on the tires.

With the DRV I am looking at approximately 300 pounds reserve weight capacity (4805 per tire).

That’s a bit close for comfort.

In your research of the Coopers, have you found many failures?

In a quick search on the SimpleTire.com site, here are current prices:

Cooper $239------ set of 4 $956

[Cummins12V98]

Do you guys think that the tires go boom if you are running close to MAX weight? There are factors built into everything. My DRV is 21k rated and for over 4 years full timing it hasn't broke nor the 21k pin box. It actually weighs 23k, I also have 17,500# on the axles.

With the GY "H" tire all you need to do is inflate per load and keep an eye on the center three ribs. If they appear to be higher than the outside ribs then you have GY replace the tire. That is the only thing that can happen with these tires other than road hazard.

This is what to look for, the only ones that seem to have this issue is some that came on 2016 DRV's.

I have no personal experience with the brand. However, the 901s are very similar in construction - being steel cased - to the GY G614 which is going out of production. I research all tires for use on RV trailers and have extensive files for all brands. Here is an older reference for the Hercules H901s.

https://www.herculestire.com/news/2015/october/hercules-expands-h-901-all-steel-lt-offering/

This one is for the H-901 ST tires.

[Cummins12V98]

What info do you have about this? What is its replacement?

[CALinSC]

"to the GY G614 which is going out of production"

What info do you have about this? What is its replacement?

It's hearsay. I know a tire retail store manager that stocks GY trailer tires of all sizes. When he found he could no longer order the G614 he was told GY was in the process of discontinuing that particular trailer tire because they are touting a new designated size (ST255/85R16 in a LRE that provides 4080# of load capacity @ 80 PSI) in their new Endurance trailer tire lineup.

[Cummins12V98]

Let's just say your guy is full of "Barbra Streisand". He did have some info that was true on the ENDURANCE.

I did a search and the only mention was a couple times on forums a couple years ago. The tires are still sold and available.

GY ENDURANCE available tires now for 2 2/3 years.

Thanks for the reply.

That BS Goodyear story has been around for years. At least since 2016. And your GY dealer bought into this?

[travlingman]

Had Goodyear G614's on mine. Just put a set of Sailun's on mine and very happy. Higher speed rated and running less pressure in them per inflation chart. Got mine through Walmart.com., but they come from Simple Tire. Free shipping to my house. Had Discount Tire do install. Walmart has them at $132.00 a tire right now. https://www.walmart.com/ip/Sailun-S637-Trailer-ST235-85R-16-Tire/430853805 Price will vary daily so keep checking their site. I have saw a low $114 a tire to $154 a tire.

[CALinSC]

Stories start and even the managers get caught-up in the frenzy.

Let's look at a fact that could have started it.

In the RV trailer industry the G614 is commonly found on vehicle certified 7000# axles. When the new 10% reserve load capacity above vehicle certified GAWRs was introduced by RVIA, 98% of all USA trailer manufacturer's were effected. Applying that 10% recommendation would make the G614 ineligible for OEM fitments on such 7000# axles. Goodyear loyalist consumers would want another qualified tire from GY and that tire could be the Endurance ST255/85R16 LRE.

[Cummins12V98]

Here is a clearer pic of the ENDURANCE options.

VERY intersection the G614 RST "G" at 110psi capacity is 3,750# and the same size ENDURANCE 80psi capacity is 4,080#.

VERY interresting the G614 RST "G" at 110psi capacity is 3,750# and the same size ENDURANCE 80psi capacity is 4,080#.



Look more closely, the Endurance is larger and using TRA standards for building ST tires. IMO the G614 RST has always been a bastardized LT tire, hence, a Regional Service Trailer tire. 98% of the RV trailer industry will no longer use them on 7000# axles because the do not meet the 10% load capacity reserve criterion for those axles.

[Cummins12V98]

Now I see that! But the same size tire is listed at 110psi for a load of 4,400# unless it's a typo???

At 80-psi they are rated at 3,640# "E" 80psi VS 3,675# "G" 110spi.

The chart is correct. It just needs to be updated as new tires have been introduced since it was printed.

When Sailun set a new standard for ST tires with their ST235/80R16 and ST235/85R16 steel cased tire they got a firm grip on that portion of the ST tire market. Since then, numerous "off shore" ST tire manufacturers have entered into the competition in that section of the market. New steel cased sizes are being introduced almost monthly. Below is a listing of some of the manufacturer's I've been tracking.

The following all produce steel cased tires in sizes ST235/80R16 LRG and ST235/85R16 LRG.
Sailun -- BlackLion -- Gladiator -- GreenBall -- Carlisle -- Hercules .

The Discount Tire Store brand Heartland, comes in size ST235/80R16 LRG.

Two have ventured into the 15" market with steel cased ST225/75R15 LRF tires. (3195# of load capacity at 95 PSI).

Hercules & GreenBall.

Another innovation without, steel casing, is the all new to the market tire designed with durability features for those off-road adventures .. It's the ST235/75R15 LRC with 2340# of load capacity at 50 PSI.

Because RVIA is pushing very hard to get all bias ply tires off the RV trailer, Kenda has - and this is the correct size - a 12" ST145/R42 LRE radial with 1540# of load capacity at 80 PSI.

[Tenbrooks]

If it's true the GY G614 is going out of production, I hate to hear it. I've run those tires on both my Cedar Creek and DRV 5er's and never had a single tire issue. It's the only tire I would consider as a replacement; however, if they are to be discontinued then I'll need to consider an alternative.

Dutch, if you can still get a set of G614's, I'd recommend doing so.

[Cummins12V98]

I had great luck with two sets of GY G614's. Looks like they are still available, Discount Tire and Simple Tire about $282.

[Notanlines]

Tenbrooks, did you read the posts? You're buying into an old wife's tale....

[ssons]

should you run max air in a tire if you don't have max weigh on it?

[Cummins12V98]

NOPE!!! Per GY Tech Support know your tire weights, use the weight/inflation chart for your tire and add 5psi to what the chart says.

Do so and you will have perfect tread wear, better stopping and ride.

Exactly, but getting your 4 corner weights can be a challenge, but the most accurate way to know what each tire is actually carrying.

[Cummins12V98]

Go to your local scales along the interstate when they are closed. Plenty of room for doing so. Use the heaviest tire per axle to determine psi for that AXLE.

Their steel cased RV trailer tires (ST) have a very good reputation. Probably because they have not been used as OEM.

Here is a reference with the four different ST sizes, one 15" and three 16". Note that the most popular 16" tires have a minimum wheel width of 6.5".

You know when that commercial policy is used, almost all of the tire's load capacity reserves are not used and they are desperately needed for RV trailer axles. The best method is to follow the trailer manufacturer's recommendations.

Not sure your point. I posted EXACTLY what GY tech Support told me to do if wanting to use the Tire weight/inflation charts instead of BLINDLY running MAX inflation.

This is for up sizing load range or if you have a RV that has PLENTY of tire capacity to run less than MAX.

I'm often misunderstood when posting about RV trailer tires. My information comes from government regulations and established tire industry standards.

RV trailer tires are any size and design the trailer manufacturer deems appropriate for that application.

RV trailer tires are governed by FMVSS (standards) and tire industry standards (ONLY!). FMCSA Regulations are not applicable with FMVSS.

So the inflation pressures found on the tire vehicle certification label are correct and minimum. Problem is, with RV trailers in the past there has hardly ever been any wiggle room as the vehicle manufacturers have fitted tires to your trailer with (sometimes) the very minimum required. Newer RV trailers will have a 10% increase in load capacity above the trailer's vehicle certified GAWRs.

The tire industry sticks by the vehicle manufacturer's original equipment tire load capacity. The do that with their canned statement found everywhere and goes like this. "Replacement tires MUST have a load capacity equal to or greater than the OE tires." Meaning by inflation.

Using replacement tires that do not conform to the OE tires load inflation chart are considered "plus sized tires." Once a new recommended tire inflation is determined for the plus sized tire it becomes the new minimum. The USTMA will allow any inflation pressures between recommended and tire sidewall max as OPTIONAL with the caveat, "Never use inflation pressures less than recommended minimum or what's on the vehicle certification label."

I can provide references if needed. They will be from FMVSS & USTMA.

Bridgestone/Firestone have a replacement tire PDF available on line that explains the procedures in much more depth and from the installers point of view. I don't keep such references once I have memorized the basics.

It's good to finally get someone here that knows of which he speaks!!!!!!!!!!!THANKS

[Cummins12V98]

Repeating a bunch of government CYA info is not the real world. For example a triple axle DRV sure as HE!! will never need MAX inflation and using the tire/weight inflation chart is wise for better ride, traction and tire wear.

Most RV's need MAX inflation because they are using the tire as a way to determine rated load.

But hey if someone wants to blindly run what the "LABLE" says have at it.

Your arguments support zero load capacity reserves provided via inflation pressures.

RV trailer tires need those reserves so badly RVIA has mandated a 10% load capacity reserve for all RV trailers in production since mid 2016. Their inflation method differs from yours because yours is derived from FMCSA regulations and the RV trailer tire inflations are derived from FMVSS.

[Cummins12V98]

They may say they need reserves but they are covering for the POS tires that most of these RV's come with.

Run QUALITY tires and you can load to MAX weight/inflation without concern. Ya don't think they have a reserve built into what the weight/inflation charts dictate?

I run quality GY tires, always have in all load ranges "E" to "H". I have had ONE tire separation from a bad batch over many thousands of miles without even a flat.

Some I had needed MAX and some I have used the charts. All with perfect tread wear.

Like I said if ya want to run what they say blindly go for it! I use my God given brain with support from GY Tech Support.

[clev]

The Goodyear 215/75r17.5 g114 can be ordered through Discount Tire for $279.

[CALinSC]

I use my God given brain with support from GY Tech Support.

I wonder how your GY tech missed this message right out of the current GY tire maintenance manual?

"Tire pressure should never be reduced below the vehicle manufacturer's recommended levels to support load conditions in order to improve the ride quality of a vehicle. The difference in ride quality is not significant. When minimum inflation pressure requirements are not met, tire durability and optimum operation can be affected."

[Cummins12V98]

I stand by EXACTLY what I said!

[Sudsysr]

Planning tire replacement in Spring 2021 on my MS 215 17.5. Currently have G114. Over $600 a tire in Canada where I live.
Following opinions of Sailun owners S265. Any update So?

[Cummins12V98]

So as mentioned $279 per tire thru Discount tire. Let's say you pay 30% premium that's still under $400 per tire.

Sailun has a good track record. I guess you need to decide if you want to support a Communist Chinese Company.

Continental is another option but not cheap as are Michelins.

I wonder if Copper makes that tire???

[Sudsysr]

Sounds like you still are ok with the Sailiuns.
I just can’t find much on them.
For Rv application and warranty.
They have a Corporate office in Canada ���� that I will call.
Haven’t looked at price detail.
Chinese manufactured.
Limited selection for size and application.
Continents does make a low boy trailer tire
Thanks

[Cummins12V98]

Personally I would NOT purchase the Sailun.

Looked and the Copper is made in China also.

[Cummins12V98]

Have the GY's given you any trouble? I am sure you can get a better price. Do you have GY Commercial Tire centers?

GY's are rated at 75mph and I "think" Sailuns are 65mph if that is of concern.

Those sorry Communist Chinese companies...Goodyear was the first global tire manufacturer to enter China when it invested in a tire manufacturing plant in Dalian in 1994. Goodyear is one of the world's largest tire companies. It employs approximately 66,000 people and manufactures its products in 49 facilities in 22 countries around the world.
Imagine what rotten, sorry dogs they are to do that!

[CALinSC]

The best way to find out where your tires or any others were built is by getting the tire’s plant code from the tire sidewall and looking it up in a plant code document.

I was reading on the forum and can relate to this blog. Our Goodyear 17.5 G114's came on our 2016 DRV. With about 15K miles, we were coming home in September from 3 week vacation. Coming across west Texas, I had a blow out. DRV is parked inside except when traveling so not exposed to outside most of the time. Got the spare mounted and back on the road. We were staying in Boerne for the night (about 20 miles west of San Antonio). It being somewhat cool, decided to try to make it home to Katy and not replace. I figured it was time to buy a new set of tires. Got up next morning and going through San Antonio bang another blowout. This was the tire next to spare already mounted. Got off I-10 and pulled into a parking lot. Worse case, pull off blowout and head toward Discount Tire. Gave them a call and they said they could get the tires but could not mount. Not for sure why but this was not going to work. Next call was to Goodyear. They forwarded me to their commercial department. After talking to them, they would come out for a road side service call to replace blowout. I told them now I have zero confidence I will make it home on the other two tires. So told them I wanted all 4 replaced. They said no problem and I was thinking cost would be around $1500. They had the tires in stock and would be there in about 30 minutes. Sure enough took about 40 minutes and guy showed up. It took him about an hour and half to break down all 4 tires and replace with new ones. Also mounted the spare back in place. I was surprised when I got the bill, $1277.33. I hope these last longer than the original set but had read issues with that 2015 tires. Guy was super nice and even gave him a tip for doing a fast great job. So if you are in a pinch, Goodyear's road side commercial service is very reasonable.

You have a lot of information here that reinforces a number of published warnings about trailer tires.

It doesn’t seem to make much difference in what tire design is used on RV trailer axles; 5 years is the best life expectancy for any of them.

A blow out at highway speed is almost always going to damage the tire next to it. It’s highly recommended to have that tire dismounted and inspected internally for damages.

The G114 is a polyester 75 MPH tire. If it’s an original equipment tire, the cold inflation pressure should always be kept at the vehicle manufacturer’s recommended pressures. When lowering the inflation pressure you may be lowering the speed restriction.

[Exposed]

I agree 100%. I also have heard once you have a blowout, the tire next to it is now carrying the entire load of both tires normally. It would stand to reason that the spare now would be in jeopardy. I probably should replace the spare as well. I have been a life long believer in Michelin tires. Has anyone switched over to them instead of the Goodyear?

I probably should replace the spare as well. I have been a life long believer in Michelin tires. Has anyone switched over to them instead of the Goodyear?

Be careful when selecting any 17.5" Michelin tires. Many of them are European designed and have a "J" speed letter = 62 MPH.

6-8 years ago Michelin wanted to become a DRV OME tire provider. They were using 62 MPH tires. I'm sure wingnut60 has more information on that than I do.

Nota sureI have more pertinent info--I have had 16" GYs on my '05--they were basically running at rated weight. Changed out to 17.5" tires/wheels, put Michelins on. They made it couple of years, then had tread separations and the famous sidewall cracks. Yes, speed-rated at 62. Went on to Coopers and Sailuns, never a failure. Sailuns on when traded. Got a '15 RSSA with the GY G114s--2 tread separations and changed over to Coopers. They were running great when traded again. Would have to say--none of my tires have had a blowout, only tread separations. GYs are on every DRV from the factory, I think--therefore, more problems arise with them just because that is what they come with. GY and Michelin are not the end all in tires--many others just as good and less expensive: Cooper RM 170; Sailun S637; others. Also, should consider going to the 235 size instead of the 215 factory size--much higher weight capacity.
Tire posts never fail to get a conversation started...

For those that don't know how the wife and I RV, we pretty much stay in one place for months before moving on. Bought our MS in May of 2010. Then we moved into it in the Spring (April or May) of 2011. Retired in June of 2014 and headed out. 20 months in Colorado, 17 months in Oregon, and 9 months in Utah before coming back to Oklahoma.


In total, I would venture that we have less than 6000 miles of travel on our tires and we STILL have the original GY G114's on the coach. So, they are now over 10 years old. We had some issues with the NeverLube bearings on one axle, so we had new axles with EZ-Lube bearings put on the coach. When we took off all the tires to replace the axles, the wife and I examined each tire. None of them were showing any "age cracking" either within the tread or on the sidewalls.

That said, before we go out on the road again, we will probably have new tires put on, and they will likely be the GY's. We've heard for years that 7 years was just about the full life of tires before aging out. We are now close to 11 years.


Not related, but when we returned to Oklahoma from Utah in 2018, we decided to replace the original batteries as well. Those had been there for 8 years, but we weren't having any issues with them. I just thought they needed to be changed.

Sounds like some good mileage/time from both the batteries and tires.

RV acid batteries that lasted that long, what's your secret.

No real secret. However, we do have a 3000 watt inverter/converter, thus we have four batteries instead of just two. As for maintenance, all I've done is pull them out about once a year and check and add distilled water.
