I am looking at my Carlise tires and it says 32 PSI and 65 PSI. Which is correct or what would be the correct PSI on my trailer? I have a H190 with a 4.3.

Thanks,

Probably the 65. One of them should say something about maximum cold pressure. That's where you should set it before every tow.

I use whatever tire pressure is stated after the max load capacity. Somewhere on the sidewall it will read "max load ???? lbs at ?? psi".

On a side note, you may want to make sure you carry a spare while using Carlisle tires, just two weeks ago I had one with a chunk out of the treads, and another with a huge bubble on the side, and the other much older non-carlisles were fine.

I'm pretty sure 65 psi would be your max cold psi as 230 mike stated.

If you do not know the exact load the tire is going to be carrying, error on the safe side and use the Max recommended air pressure.
For even tread wear and proper inflation, tires need to be aired up to the proper PSI for given load. This goes for our cars, trucks, motorcycles, ect...... most of us dont get into the exact science of proper tire inflation and just go max PSI.




I have have good and bad luck with every brand of trailer tire. I think it has more to do with lot quality vs. brand of tire. Also much has to do with how a tire is used/abused and maintained. Many trailer tires the side wall gets damaged, (curbs, sidewall flexing beyond design/twisting from jackknifing trailer backing up tearing carcase), then tire fails next time we take it down the road and it heats up a little and we blame the tire manufacture. Just my 2 cents.

Mine is a tandem and I always run 55psi - regularly tow long distances with no problem. 35psi would be way too low and get the tires too hot leading to an almost certain failure. If yours is a single axle trailer, then 65psi sounds about right.
