I'm extremely impresed by these tires. They are fantastic. They have ULTIMATE dry grip and traction. They are very comparable to the Goodyear Eagle F1 Assymmetrics I just had previously to these, but at a much cheaper price. In fact, after a few canyon runs on highway 2 in CA (Los Angeles Crest Highway) I'd say these out perform the Goodyear F1 Asymmetrics and are the superior tire. They have slightly more ultimate dry traction and it seems a bit more effortless and complaint free doing it. I can't believe how high the limits of these tires are in speed around sharp corners.
Time will tell on whether the treadwear can be better, but they certainly can't be any worse than the Goodyears, and at $40 to $80 less per tire, you can't go wrong with these.
