This might be a dumb question but does anyone know how much air I should put in my aftermarket tires? Here are the specs:

Front:
19x8"
Tires: Toyo T1-R 235/35/19

Rear:
19x10"
Tires: Toyo T1-R 275/30/19

This is for an 06 IS350 and the factory recommended pressures are 35 in the front and 37 in the rear. Thanks!

i run those at 40 psi all the way around. imo it helps to keep the wheels protected from bending. that's debateable but i've been running tiny profile tires sinc e 1998 and have NEVER bent a wheel.

Do you think I'll be fine if I run them with 38 in the front and 40 in the back?

it should be. really depends on your roads, how attentive you are to new potholes and your avoidance skills!

If you're running air sensors you should stay with the factory 35, 37psi.

cant you re calibrate the tps for whatever pressure you choose to run? i know ont he older cars, there was a button under the dash that would calibrate the sensors for whatever pressure you set them to.
