I must say I am disappointed with these tires. They are not very uniform with noticeable runout. Even though they were installed at my BMW dealer to BMW specs, there is still vibration, though balanced down to 1 gram. Of course, when this sort of thing happens, it really highlights one of the biggest problems buying tires online: it's much harder to have this kind of thing handled without paying a significant amount to have the bad tire(s) dismounted and shipped back, and then there's the wait while new ones arrive. I never had uniformity/ride issues with Michelin. I have learned my lesson. I'll be looking for someplace local to buy my next set. The relatively small amount of money saved isn't worth the hassle.
