Psi For 235/45/17 Tyres? - tyre pressure.  

there should be a pressure indicator on the tyre.

however, im currently running 36PSI in the 235/45/17's that im running on the front of my skyline

Personal preference.

Somewhere in between 34-40psi should keep you happy.

ROCK ON

as a rule of thumb, the lower the profile the higher pressure you should run. I run 40 psi on my 255/40 tyres.

Depends on car and driving style. If you run higher pressures you generally get better mileage but a harsher ride. Lower pressures give a softer ride but let the tyre roll around on rim and where edges faster. 38psi ish is around the mark.

i would put 38 on the front and 34 on ther rears when u drive heat gets into the tyres and rises the pressure a bit like 2psi
