On my second set of these tires and have to say they are one of the best tires I have ever used. I have pushed these tires to the max in all sorts of conditions and they have stood up to the task without any problems at all. I have compared these to mich ps2's, ps3's, Contisport 3's, and p zero's, and given the choice I'd have the vorti's over all of them. I have these on a180 bhp audi a4 tdi and would recommend them to any enthusiastic driver. Excellent quality, excellent performance, and excellent value for money.
