This is my 2nd allroad and still under Audi extended warranty. The front tyres are Goodyear Eagle F1 225/55Z/R17 and have both worn considerably over the past 4K miles on the outer part. Most of which has been smooth European motorway. The car does not drift on a level surface. The rear tyres are Goodyear Wrangler allroad 225/55/R17. My understanding was that strictly speaking the allroad wheels should only be fitted with allroad tyres because of the rims. Is this correct ? All assistance greatly accepted.
