Boy, can I second Beelzy's comments. I had a rear go at 60MPH with no place to turn off.; it shredded. Fix-A-Flat would not be of help, but luckily my spare would....had it had air or I had an inflater. Long story short, I made it to help and all is well, except the cost of a new tire that had only 2500 miles on it (pic is before cleaning!).
Been years since a flat had occurred on any of my cars, but I guess it happens...and it sucks when it yours.
