First thing I would do is dump the NEXEN's that WILL have a tread separation.

Now the second thing is get your front end aligned to 1/64" toe. This WILL stop the outer front tire "STEPPING".

Third is proper rotation. Leave the rears alone! Fronts separate the tires from the rims leaving the rims at their current location and move the tires side to side with the rotation staying the same. This will put the outside of the tire to the inside. This will even out the tire from outer edge wear from turning.

Now the fourth is proper air pressure. The fronts ALWAYS leave them at 80psi. the rears when you are running around unloaded 30psi is more than enough. Loaded that is a question that cannot be answers properly without knowing what your actual weight is on the four rear tires. Fully loaded go to the CAT scales or any Highway scales. Now that you know your weights you can know your proper inflation.

Lookup the load/inflation chart for your tire size and load range. Add 5psi to the rear tire pressure on the chart. If you want to dial in the fronts do the same and add 10 psi, this will get you to 80 or darn close.

If you follow my recommendations that have been proven to get the best tire wear you will be a happy Camper!

Tires in pic have 40k with lots of tread left using the methods above. My truck 2015 RAM DRW weighs 16,000# fully loaded, with nearly 1/2 the miles towing.

I run 30 unloaded rear and 67 at full RAWR 9,750#

By 1/64” toe, you mean toe in, right?

I just saw this thread. First off, how you can still have nexenís on a 2018 is beyond me. Two of mine separated by 18,000 miles. Replaced all 6 with Michelins and Iím at 66,000 with lots of tread left.
I have to disagree with the tire rotation suggestion. I never reverse the direction of any tires. Manufacturer recommended 6 wheel rotation is, front to outside rear, outside rear to inside, inside rear to front. I bought from Discount Tire and they dismount all 6, rebalance and rotate at no charge every time I ask in any city I happen to be.
As far as tire pressure goes, I run whatís printed on the door placard. Front, 80psi COLD, rear, 65psi COLD, loaded or empty.

Old Guy did you actually READ what I said about rotation?

Also if you are running empty for any length of time you sure could improve your ride comfort by lowering the rears to 30-35psi.

YES, NEXENS are pure junk!!! That is why I had them removed at 200 miles and sold on CL for $650 the first call. Replaced with Michelins. They only made it 40k and was given around $1,000 to buy any tires I wanted under their warranty. I went with Michelins again and now at 46k with lots of tread left.

I went back and reread your post and yea, I misread it. Sorry about that. Iím still not convinced driving around on severely under-inflated tires is a good idea. Anybody care to weigh in?

Cummins12V98-how do you get your rear tires at 35 psi without the low pressure warning driving you crazy? Can that feature be disabled? I just bought a 2021 Ram 3500 with Nexens. I’m now concerned about them. What do I look for in regards to separation. Do they come apart like a blowout or get a bubble?

They are NOT under inflated. There is a reason there is an inflation chart for every tire. At 35psi the lowest number I have MUCH more capacity than my actual weight.

Fact is with the proper inflation for the weight you have a better ride, better traction and better tire wear.

You don't have a TPMS you have a way to see tire pressure but ZERO warning with any 3500 RAM. Only 2500 RAM trucks give a warning.

NEXEN tires at around 25k +- have tread separation and possibly tread loss.

Go to Discount tire and get a set of their best Michelin or GY's and sell the NEXEN's on CL. Sold mine for $650 but I bet now with higher pricing they will net you at least $1,000.

Another small thing request they mount the balancing weights out of sight.
