I've only had a blowout once in the 5 years I've been driving, and it happened in the Breeze; I had picked up a piece of metal from the parking lot at the Technology Center when i was getting my Automotive Degree, and it had actually blown out the sidewall. a little bit after that, I went to the local Pull-a-part, and picked up a full size 14" Steel wheel, and had a Brand new tire put on it; that Full size Spare has NEVER Seen Road Ever Since I put it in, because after that, the Breeze's engine Blew Sky High. of course, all Three of the cars we drive now (Dad's Silverado has a full Size 17" spare, The Breeze's Replacement has a 14" Dunut, and my mom's SX4 has a 15" Dunut) the Spares in them have NEVER Seen Pavement (and Hopefully NEVER Will) but one of my Pet Peeves when driving is seeing people driving on a Donut Spare as if its a Full Size Spare! (the Automakers need to put BRIGHT RED Warning Labels on the Space saver Rims that say DO NOT USE YOUR SPACE SAVER SPARE TIRE LIKE A FULL SIZE SPARE TIRE!)
