I just found two bubbles on my M sport tires! One on each of the front tires. This sux, now I need a trip to the dealer. Worst part is I have not hit any jarring potholes you would normally associate with damaged tires/rims. I have hit my fair share of normal potholes though. Oh well, I only have 4000 miles, I was hoping to get to 15k or so miles and THEN have to replace them under warranty (I have the 5 year BMW insurance).
