I appreciate the owners handbook would say, but what do club members run their Stilo on (pressure wise) with 17" wheels?

Just wondering if experience has taught not to follow the handbook.

i put 32psi in my 18's mate, and i have done with all tyres, 32psi seems to be just right for me on any size of tyre. anywhere from 28 - 32 psi would be good mate

Off the top of me old head the stilo uses 2.3 bar pressure..general consensus is fiat got it wrong ..2.3 bar is for the standard steel 15" wheels and if you have alloys [for example ] 16" then add an extra 2 psi..as a general rule add an extra 2psi per extra inch of wheel diameter..on mine and the wife's 17's I was putting in 35/36 psi..
