tires vary. it should be listed on the tire side wall. mine is 44 max psi.

but i have 37psi in the front and 40 psi in the rear

Yup id agree with you... it varies

I have mine at 37-38 psi...

make sure you check you psi only when the tires are cold... dont bother after 20mins of driving and then checking... I usually check in the morning when I go to work at 7am

Rule of thumb: for every inch of rim increase, add 2-3PSI (cold pressure).
