I have the pilot sport a/s on the stock rims now. The problem I am having with them is they keep getting a bubble (Right side only), or they blow out. I bought them and have had them changed under warranty, but every month I am in to get a new one. The roads I drive on aren't that bad and I avoid all the dame potholes in the city. It seems like they just blow or bubble it up on the smallest crack in the road.

Just curious if anyone else has had the same problem with them?

Also I will need new tires again before winter, any suggestions on tires that I won't have to change in -2 weather this winter?
