Nowing that a c5 corvette came with runflat tires, and had read many reviews about the car with OE tires , I didn't expect much from those tires. I was not dissappointed. They may be accetable to those folks who drive on smooth roads but those are few and far between in the good old USA. If you are not concerned with Ultimate Handling and High Speed capability plus Fat Tire appearance I can suggest something that will make a c5 Corvette a vehicle that you will enjoy if your driving is city and highway type. I installed Pilot HX MXM4 235/50/17 on the front and 245/45/18 on the rear. The difference is night and day. No more darting. The ride is, well lets just say it's 500% better and their is no more tire noise to have to listen to!!!!!!!!!!!!!!!!!!! Although these tires do not have the speed rating of the OE tires, they are more than sufficient for city and highway use. If your needs are for high performance then the OE or better tires are for you. If you want a c5 Corvette for city or highway use that is quiet and comfortable the Michelin Pilot HX MXM4 is the tire for you. When looking for a good ride, stay away from tires that have sidewall inserts. Their purpose is to stiffen the sidewall for better handling but ride quality is SEVERLY REDUCED. Your best option if you want performance and good ride is to have two(2) sets of tires. That is the ONLY WAY to have your CAKE AND EAT IT TO!!!!!!!!!!!!!!!!!!!
