Tire psi question

[lc7404]

Hey guys I just threw some amp pro 285 5520 on the tank. My question is the tire shop had 60psi in them when I brought it in for a oul change they dropped me to 35 based on the door .who is correct

Certainly not 60 PSI! I would suspect about 35 would be correct, but if you want to get geeky about it do the chalk test. https://www.intercotire.com/using_chalk_method_determining_psi

60psi?!?! I agree with alrock, definitely shouldn't be running at 60psi. My tires run around 35psi as well so I would agree with that choice.

On the H3 with 35" tires we ran 37 PSI. If we ran 35 PSI the TPS light came on more often.

Load range of the tires and rim width vs tire width all play into contact patch along with PSI. The load range E 37x12.5s we are running at 28psi and "almost" have the right contact patch with 4 adults and gear
