You didn't say if the low profiles were also run flats but I'm assuming they are since it's a new car. Yes, low profile run flat tires are subject to blowouts, especially when hitting a pot hole! I had two blowouts within 2000 miles in my new 2008 GS460. Someone in the club suggested I buy new tires without the run flat feature which would also provide a much smoother ride due to the elimination of the hard wall casing in the run flats. I bought new Michelin Pilot Sport A/S Plus tires and have had no problem since plus the ride is a lot smoother without experiencing any appreciable loss of performance. Since the car did not come with a spare, I also spent 3 hrs convincing the dealer that a spare for my car was available and was successful in buying one.

Just joined today after experiencing two flats on run-flat tires on my 2008 GS 460 within two months. Tires have 25,000 long distance highway miles after 29 months so tread is still in excellent shape. Flats due to pot holes. Question: can this phenomena be attributed to a design flaw or can it be mitigated in any way? I'm going to my dealer right now and demand some adjustment although I seriously doubt I'll get any satisfaction. I've read the postings. This situation is ridiculous!! Should I replace with Michelin sports as suggested by one member? And what is the full name of that tire model so I don't make a mistake and buy the wrong ones.
