Should have less in the front. Try 30psi.

I think you'll find it in the hand book, or did you go with that? There is definitiely a diff front to back.

Here are the recommended pressures... and tyre sizes too for which the vehicle's engine management and all the other electronic systems were ''calibrated" from factory, exceeding with more that 5% those dimensions without proper tuning for that will lead to an unhappy end for one reason or another

How do you do a proper tuning when using different tire size?

Not easy and it's a too long story, i had many posts about that... in a nutshell the cooling has to be enhanced and the fuel map addapted to the VSS(vehicle speed signal) input as to keeo the torque and EGT within decent limits, addapt the diffs or transfer box ratio to them eventually... which means that with big tyres an EGT gauge is compulsory.
