Had an interesting experience today, a high speed blow out, on the Interstate, the car didn't wobble or anything, there was a huge bang (sounded like something hit the car body very hard) then a few seconds later the low pressure light came on...so I slowed down from around 75 mph to about 60 mph, tried the steering and drove maybe another mile to a safer place to stop... sure enough the rear was flat. With three holes in the side wall. Not much point in using the run flat for that.
Called Chrysler who arranged for a free tow to the dealer... who arranged for a free hire car (actually Enterprise hadn't got a car spare so they drove me 25 miles home - I was quite impressed).
The tire turned out to have three nails in it !!! But I have to say I was amazed at how well the Michelin Pro sport handles in a blow out. Sadly the experience will cost at least $380 but oh well...
