Here in Western New York, we have had the harshest winter ever. Today I hit a pothole while completing a right hand turn, the right rear tire hit the hole, I was only doing 5-10mph, then soon after the tpms went off and said 1psi........DANG IT!!!!! Lucky for me that there was no rim damage, only a cut side wall. I called Cadillac services and they sent out a service vehicle(Escalade) from a Caddy dealer. The service guy was quick to arrive, and changed the wheel with their loner spare(my car has none). The top notch service was no charge, and a new Goodyear cost me 160 bucks out the door at a local tire shop(Dunn Tire). Watch those potholes!!!! low profile tires don't stand much of a chance against them.
