A new study conducted by J.D. Power and Associates says run-flat tires are more prone to replacement compared to conventional tires.

According to this analysis, almost one-third of those who bought a car with run-flat tires in 2011 or 2012 had to replace at least one of them due to a blowout or flat. Only 19 percent of those who acquired a car with regular tires had to replace one of them.

These results are based on the answers given by more than 30,000 car owners who made the purchase of 2011 or 2012 models and used the vehicles with the original tires. This study mentions the most frequent issues are punctures, road hazards, excessive road noise, slow leaks and fast tread wear.

J.D. Power and Associates has come to the conclusion that 728 (of a 1,000 point scale) luxury car owners with run-flat tires were satisfied with their purchase, compared to 739 users of luxury vehicle owners equipped with regular tires. As for performance vehicles, 665 owners were satisfied with their cars running on run-flat tires, while 732 people were happy with their automobiles fitted with standard rubbers.
