I've had these for several months and now changing the rims from 18 to 19 and will buy these again. I have done some high speed driving, sharp high speed cornering, sharp braking, even some burnouts and they handled everything great. They are now half way down but considering my aggressive driving I'm not surprised. From what I see I could still go for one or even two moderate driving seasons. They are a bit slippery on wet but not too much, they still do a great job especially for this price.
