Recommend Tire Pressure

[Bramic71]

Hello all. Just had a new set of 275/60/20 Wildpeak A/T3W (Not LT) Installed, and acquired a fiberglass topper as well. The door jamb recommends 35psi, which seems a little too low and a little squishy when I press on them. With the extra weight of the topper, should the pressure be changed? Just curious what pressure has worked best for you guys in this situation. Thank you

I run 41 to 45 with the stock 20'' SRAs. When I first got the truck I had the tires at 36 and hooked on a trailer set the tow mode and that triggered a low tire pressure warning and had to put in 40# to stop the warning. From then on I add air when one tire hits 40 cold and I like the ride and handling at 45 along with the better mpg.

With the 275/60-20 OEM tires I run 42 normally and 45 anytime I’m towing. 35 seems low for a 60 series tire IMHO.

best,

Here is a video Custom Offsets sent me on what tire pressure to run.

Here is another video on tire pressure with the chalk test.

Br careful, my truck recommends 39 psi which I run them at but the tire says 44 psi max. These are the stock tires from the factory.

Thanks for the info. Might be chalk time.

The difference here being what the manufacturer says you should run with the gear, trans, tire and weight capacity. The pressure on the tire is simply stating that you should not run more than 44 psi max. The tire is not designed for anything above that. The two are not necessarily related.
Example, my truck came factory with LT-E rated tires with a recommended pressure of 43 psi, however the tires can handle up to 80 psi.
