We have classified the 2 complaints from 2012 Audi A7 about TIRES into the following categories.
Over the past 6 months 3 out of my 4 continental contiprocontac tires have developed "bubbles" in the side wall. when the 1st (or even perhaps the 2nd) tire developed this problem, it might have been attributed to pot holes. it is summer now and i have driven very little but the 3rd tire has presented this problem. i keep the tires properly inflated. all of my tires are routinely examined personally and by the tire company when replacing previous tires. updated 4/24/2015*js
