Both my 300D's have the factory size (P195/70R14), installed in last 3 years. One has Yokohama Avid S Touring from America's Tire (or Discount Tire). The other has Cooper Response from Sears. Both tires have straight channels, which I think looks better, and makes it easy to measure toe-in w/ a tape measure. I can't say which set performs better (not a tire aficionado, ditto for audio).

Sears was a rush job on a Sunday before my son took the car away. We prefer America's because they have stores all over CA and I always get the road-hazard warranty, which we have used many times.
