I was wondering how can a person figure out the tire pressure for bigger tires. My truck is stock for now I don't tow or work with the truck.

I usually start off with 35lbs, and keep an eye on tire wear, and adjust accordingly. I also uasualy end up with less pressure in the rear, due to the fact it is much lighter. When/if you tow, add pressure to the rear.

Don't recall seeing a tire that did not have the tire pressure range on the sidewall. If you vary from that and wear indicates such, all warranty is off.

The side wall and the sticker on the door jamb, refers to max load in bed or when towing. Results may vary.

Tire sidewall will tell you MAX inflation pressure. That's gonna vary by what load range your tires are. For unloaded, I usually start with around max - 10 pounds, and see how it handles. If you are feeling really froggy, you could use your infrared thermometer to check temps across the tread of the tire after driving for ten minutes or so. You want even temps all the way across. if the center is cooler, add pressure, if the center is warmer, reduce pressure.

you can also, use chalk, draw a line across ur tread. drive it some, and then see how the chalk wore off. if it didnt wear in the middle too much then add some air, if only the middle wore, then lose a little.

but i found about 40 in the back, and 45 in the front for me.

Thanks for all your help good peoples
