We have a 2009 A3 1.9tdi Sport. The tyres are 225/45/17 91V. I need a new set of 4 tyres and the goodyear Eagle F1 Asymetic 2s seem the best at the moment and good value too. The thing is the extraload tyres in the goodyear range (225/45/17 94Y XL) are slightly cheaper than those that are fitted. I see the 94Y XL as betterment over the fitted once. Does anyone see a problem with fitting these?
