Sorry to revive this thread, but I thought I would share my experiences with this set of tires...
Buyer Beware. I have had to replace 3 of these tires in the last 6 months or so. The sidewalls are made of birthday balloons, they are WEAK! I hit a rail road crossing going only about 10-15 mph, it was a jolt even at that speed, but I didn't immediately perceive an issue. Two days later I noticed a vibration in the steering wheel. I pulled over to check things and I had developed a large knot on the drivers front tire. Now, 3 months or so later we were going out to eat. They were doing construction on the road and had excavated a couple inches of asphault near a bridge so they could repave. This left an exposed edge at the bridge / road union. They had a bump sign, but it was right at the bridge. I hit the "bump" going about 55 mph. It put a knot on the passenger front tire and bent my wheel. I was able to file a claim thru the insurance of the construction company and get that paid for. Then yesterday (now with about 20K on this tire) we picked up a piece of metal in our tire while vacationing in Myrtle Beach. I got up on the departure day to find I had a flat drivers rear. So in the rain I changed to the spare. Walmart in all their glory refused to repair it after us waiting for over an hour. We then drove 20 min to another tire place where they fixed it, but it took 1.5hrs. We had a 10.5hr drive ahead of us and instead of leaving at 9am we left at 1:30pm.
I WILL NOT buy another Dunlop SP Sport 01 A/S...period. I'll put a generic tire on before I put this tire back on. I will be out almost $900 in just tires on this car in the last 6 months (not including a bent wheel). This is senseless money to be spending on stupid stuff like this!
