I'm getting an old Quattro back on the road after years of being in storage, and I need new tyres. Standard tyre size is 205/50 on a 15" rim (I'm not sure of width of rim). I have a budget of about £80 per tyre in mind, but I'm flexible on budget if there is good reason to spend more. Ideally, the characteristics I'm after are low rolling noise, and excellent dry/wet road-holding. Any suggestions?
