I had the original tires on this Shelby and they were 4 years old when i bought the car. I hated this tire with a passion, I thought it was just absolutely horrible. THEN, I got a brand new set, night and day folks. I went from a car where I could come around a cloverleaf onramp and roll on the throttle and immediately get the car in a drift to a car that can ---- near have the pedal to the floor and still just plants to the ground around the corner. Launching used to be horrendous because the old set just spun and you'd hit second gear and the ------- end would be going side to side until you were doing 70. With this new set, you can get a solid launch from higher RPM in 1st, when you dip second it'll leave maybe 6ft of rubber but she hooks and you're GONE. I had the tires installed and immediately left on a 5,000 mile trip up into Canada and down to South Carolina back up to Maine and ending back in upstate New York. The tires had some road noise to them but that is to be expected of performance tires. I used to run Pirelli Pzero Assymetricos and Michelin Pilot Sport 2's and they both were as noisy. It was nowhere near unbearable and the ride comfort was A ok. The only time you notice a rough ride is when you're on bad asphalt or cobblestones. In my opinion, I'd definitely buy them again, especially considering tire rack sold me them for around $660 for the set and Ford quoted me $1940 not even installed. Final note, the last set went 26,000 miles before I replaced them and that was because I burnt up the rears, the fronts still had a good bit of tread on them. Thank you tire rack!
