As you know, no matter how could you car is, the tires are still the ones that hug the road and cheapo tires dont jive with an expensive body. I recently replaced my favorite BF Goodrich Touring T/A HR4 ( rated 380AA) with BF Goodrich Comp T/A HR4 ( rated 360AA ), and I could feel an improvement in the handling right away. The Comps are listed under BF Goodrich's " Performance Tires" category. Reviews say that the Comps are great in handling and stopping, in rainy conditions, but they are not so good on snowy surfaces. Someone said that they don't last as long as they should, considering that they are rated a 360. I'll know after some time, I reckon.
