[QUOTE=Homeboy981;340926]36psi ALL the way AROUND? Isn't it supposed to be 29 in the fronts? …unless you "squared" your setup on all the same rims and tires.
Again, that is for COLD tires pressure AND regular driving. If you are going on the track or going to drive more aggressively adjust the pressure DOWN - as the tires will heat up alot more more at high speed. Don't know pressures for AX, sorry.
Porsche specs lower psi in the front tires because there is less weight on the front tires.
If you install larger tires on the front you should reduce psi because the larger tire has a larger volume of air, thus same psi in a larger tire = more air than you had before supporting the same amount of weight. Temporary spare is a good example, smaller tire needs 60psi to properly support the vehicle.
In all situations too much psi is a minor problem, normally only ride comfort is "impacted". Too little psi is always a problem, as every Ford Explorer driver should know!
