Tyre pressure question - gone from standard 16" to 17" (225/45x17) - what pressure?
Car is a year 2000 Audi A4 (B5 chassis) 1.9 TDI SE with the 115 output engine.
Just put some nice 17" alloys on, with 225/45x17 tyres.
Anyone know what the pressures should be? on standard it stated 32psi all round, I've done some maths (which helps compensate for diferent sizes/pressure/air volume etc), and I'm caclulating that I need to be around the 34.5psi mark to 'match' the originals.
Does anyone know for sure what the 'standard' pressure should be for my car on 17"s?
