Can someone post the recomended tyre pressures for 205/50 17 and 225/45 17. Reason I ask is I'm running 205`s on the front and 225`s on the back!

I'd just stick with what it says in the handbook.

The manufacturer's recommendations for the Octy vRS for 205/50/17s are 2.1 bar front and 2.2 bar rear. I have made the transition to 225/45/17s, for a while I had the 225s on the rear with 205s on the front. I stuck with the manufacturers recommended pressures and have had no problems

Cheers whats 2.1 bar in psi? Sorry old school!!

Use the converter in our Links section here. 2.1 bar = 31psi; 2.2 bar = 32psi.
