Carmakers increasingly under fire for using run-flat tires
Apart from the high cost of replacing the tires, run-flats are harder to come by and they don't last as long as regular tires either. Though the idea of not having to worry about changing the tire if it gets punctured sounds great, run-flats only have a range of about 50 to 100 miles once the rubber is damaged. Not much solace if you happen to hit a spike in the middle of nowhere.
Along with BMW, Corvette also has run-flats, and Toyota and Honda put them on some minivans.
Apparently, run-flats were introduced because consumers want "the smallest amount of hassle in their lives," according to an engineer from Bridgestone. Perhaps it's time drivers were forced to learn how to change a tire as part of their licensing tests.
