These came mounted with a staggered set of 20" Black Giovanna Dalar wheels installed on a modified 5Spd 2006 Ford Mustang GT Convertible w/ 25k miles. 20x10 rear/ 20x9 front. The fronts are PHI-R's and the rear PHI 2's. Read reviews all over the net and had some doubts due to the lack of info on these. After researching I found the reviews were 50/50 positive-negative online on various sites. I did notice (and read elsewhere) that the tread pattern was almost exactly the same as the Continental Sport Contact 2 - even to the sidewall. Speaking of which, the sidewall on these Accelera's ARE THE BEST I've ever seen on a tire - and, again, almost exactly the same as the Conti SC2's. After 2 weeks of driving, the tires are great. They ride smooth and quiet. Turn in response is crisp and feedback is excellent - almost telekinetic. I tend to drive like a maniac and so far (2 weeks) the tires can handle what I've thrown at them. High speed cornering and straights, weaving in and out thru traffic they ride beautifully even with going +2 on the wheel size and width. Usually with wider tires, understeer occurs but these tires are accurate. I HAVE NOT driven them in the rain or snow. I spend way too much time, money and effort detailing my car to show-room clean and refuse to just drive it in the rain, let alone snow. I have 2 Jeep Grand Cherokees for that. Also, the Mustang has way too much torque to drive in rain/ snow. Even with the brand new 235/50-18 BFG Sport Comp 2's I had mounted on the stock wheels, the Mustang still spun in the rain accelerating from 1st gear. I'm a hardcore auto enthusiast/ experienced DIY mechanic and have run many performance tires on 5 different sports cars: BFG KDW 2, Goodyear Gatorbacks, Firestone SZ50, BFG Sport Comps 2, Pirelli P Zero Rosso, Yokohama's, Falken FK452, Bridgestone Potenza RE050, Dunlop Direzza's, and so on. I can say these Accelera's are EVERY bit as good as any I've driven on and for the price, BETTER. I'd buy these again although I'd like to try the Goodyear F1 Supercar 305/30-20 on the rear wheels and 255/35 front. I'll be back to update my review after 5000/10000 miles although I only put about 5000 miles/ year on this car.
