Hello all, I just bought a 2004 S4 I really like the car but I was wondering about tire sizes. The car currently has 235/40/18's I was wondering if it was possible to put on 245/40/18's on the stock rims. I read in the owners manual that you should not not change tire size with the quatro system. Is this true has anyone installed a different size tire on the factory rims. I have owned corvettes and this was not a problem but the audi is totally new too me. Thank you for the help

 

Yeah they will fit
