What tyres on a Audi A6 Avant Le Mans 3.0l TDI

[F18RSC]

I have Goodyear Eagle F1 on the rear 255/35/R19 and chinese ones on the front (Thanks dealer) Its a 2010 car and I am in need of 4 new tyres, throwing the chinese ones away!

Local garage has recommending Vredistian Tyres but the have E C 70Db compared to C A 69db.

I am little concerned that the economy spec is E! They are saying that the Goodyear Tyres will not be in stock until the 25th of November! I will ring a few other garages tomorrow.

Any other recommendations? I do like the rim protector that you get on the Eagle F1's

Thanks
