This is the first time I have ever purchased a tire twice in a row from the same MFG. This S drive tires are the best tire I have found yet for a value added tire in the performance line of any MFG. tire on the market for the price. The first set of S drive tires went 33,000 miles and I am a sprited driver. This same car I have had 3 other MFG. performance tires on and was only able to get between 15,000 to 23,000 miles of service out of them. That is why i have put a second set of these on this same car again. My son have choosen to try two other brands of tires on the same car as mine and they still do not get the mileage ( around 20,000). If this car last thru these tires I will force myself to try a different brand. To date overall on five different vechiles I have used Yokohama tires of different ratings and feel that Yokohama tires are hard to beat for the value.
