Can anybody advise on winter tyres for a RS4 Avant on 19inch alloys. I thought it would be simple! I had selected Continental winter TS830Ps then realised I have 19inch wheels! Audi charges £1438-£1637 (and don't have any). I'm now thinking it might be better to wait until the rush is over and buy for next year. I guess buying some 18inch wheels might offset the higher 19inch premium over a few years, but most users seem to use their winter tyres for 3 years so I doubt it will save anything.
