Wider tires pressure

Guyfromthere · 07-23-2016, 03:46 AM

Hello people, i know that recommended psi for stock 18s is 35psi. I changed to 270/40 rear and 245/45 rears on stock 18 rims. Do i keep inflating at 35psi? Thanks for your time

I've just put 265 on the fronts and 305 on the rears. I'm staying with 35psi until I get some miles on them and see how they are wearing. If they are wearing faster at the center of the tread then the pressure is too high. If they are wearing at the inside and outside edges then the pressure is too low. 35 psi is a good starting point. Keep an eye on the tires and adjust accordingly. Good luck!
