99 Camaro SS
I have owned this Camaro SS since new. It was ordered with the SLP exhaust option and the 17" Chrome ZR wheels. After using up the original Goodyears, I put on Avon(acutally Cooper made) tires stock size with mixed reaction. Great grip at first but eventually the faded away. I now have the Continental tires listed on the car and they have made quite a difference. Great overall handling and ride quality. I personally like the asymmetrical tread design on this tire, and other Continentals I have had. Looks like they cost more but I think worth it.
