We finally have our new new set of Goodyear tires on the RV (thanks Goodyear!).

We also purchased a IR temperature gun to monitor the heat. It's a great 'toy', but I have no idea what is 'good'.

Today while travlling, with OAT at 89 degrees our tire temeratures were
Dooley tires - 120 degrees
Front truck tires - 125 degrees
RV tires 130 degrees

Does anyone have any idea what is 'normal' or dangerous/unsafe?

They seem pretty close to what I see on ours. Sometimes I have even higher temps on the trailer tires especially on the sunny side. I do find that the door side rear trailer tire has a few more PSI increase and bit higher temp than the others. But not alarming.

When I check the temps, I don't worry too much about the actual temps, but look for the odd one out, which can indicate a possible problem. Same goes for brakes, truck hubs and rear gear.

With the Pressure Pro, all the pressures are monitored and gives a pretty good indication of the increased temps.

Cheers,
Bill

I think Ponch has mentioned before that information he has said that an important aspect of tire temperature is how much it changes from a "cold" tire temp state to a "hot" traveling temp. I believe he said the amount of temp change was relative to correct/incorrect tire inflation pressures, for the load being carried. Having an IR temp gun should make it easy to know what your tire temps are, and whether any inflation adjustment is needed.

Maybe Ponch , or other tire "experts" :wink: can provide some meaningful info on this subject.

The best thing you can do to extend the tire life is to make sure the weight of the trailer / axle is inside the tire's range and that the tire is inflated properly to the load when cold before you move the rig.

The weight will require the services of a scale and preferably someone like Stacy for an independant wheel weighing.

The second part requires a guage that is reading correctly. That's a situation that you can't count on just buying a guage off the shelf. They are really not callibrated that well. If you can get to a tire store ask them if they would check your guage against their master guage. If it reads accurately set it aside and get another guage and check it against your "master guage". If it reads closely use the new guage to set the pressure and your "master guage" to check the accuracy of your working guage from time to time.

How ever you calibrate your own guage, never figure the one on the airhose is reading correctly. Use a seperate guage to check the tires and check them every day you are traveling before you move. It's part of my pretrip check before I hook up the truck.

130 degrees F is nothing to be concerned about.
