Tyre Pressures 2003 A4 2.5TDi Quattro Avant Michelin 235/40 ZR18(95Y) PS3

I have the above car and understand that 18inch wheels are not standrd.
Local Audi dealership could not help with accurate tyre pressures for these wheels and tyres.

Can anyone offer any advice on what they might be, or how to calculate the correct pressure?

Grateful for any advices.
Many thanks

I would presume anything between 35 - 40 psi is alright.

Also depends on weight.

Ive found that 40 makes the steering light too.

But 18's were an option.
I have them on mine and I run them at 36 all round.

Thanks very much guys.
I approached it from another angle and rang Michelin, where a very helpful lady looked up my car and told me the pressures needed.
Please note, this is better then their website which suffers hopelessly from slow updates from france.

She advised that for a 91Y (which will be the same for the 95Y) that standard load should be 39F 35R and laden (4 adults plus bags) 42 square. Therefore your advice was spot on, many thanks.
Contact number for them is :
