As fuel economy has become a major factor for automakers in recent years, tires have been one of the many avenues approached to maximize vehicle efficiency on the road. By installing low-rolling resistance and run flat tires, automakers are looking to eliminate the need for spares on board and increase overall fuel economy numbers, though owners have made it clear that the benefits come with noticeable drawbacks. Overall, vehicles with run flat tires netted a rating of 728, compared to vehicles with standard ones, which scored 739. Amongst performance vehicle owners, the gap is even more exaggerated: 665 for run flats, 732 for standard tires.

'Automakers are trying to reach the next level of fuel economy, and are looking to their suppliers-in this case, tire manufacturers-to help them get there,' says Brent Gruber, director of the global automotive division at JD Power. 'The challenge is doing this while finding tires that meet customers' expectations. Run-flat tires are not currently meeting those expectations.' He also added that, 'Owners of performance sports cars with run-flat tires say they 'definitely will' recommend their tire brand to friends and family only half as often as those whose car is equipped with standard tires (14% vs. 28%, respectively). That has a potentially tremendous financial impact on tire manufacturers.'

Though run flats allow drivers to continue driving after a puncture has developed, they need to be changed much more frequently. On average, owners with standard tires replaced them every 22,559 miles, more than 6,000 miles beyond the average lifespan of run flats. Blowouts were also nearly twice as likely for run flat tires, creating dangerous accident potential and the need for additional tire replacements. Of owners included in the survey, 33% with run flat tires reported having to have at least one tire replaced. Only 19% of standard tire owners reported any such replacements.

Unlike regular tires, run flats cannot be repaired if damaged, and often need to be replaced in pairs, rather than as a single tire to ensure that they wear in unison. This presents additional financial strain for owners, who find themselves in need of two new tires in the event of a tire suffering damages. Each of these concerns has added up into a package that owners are growing increasingly unhappy with. As many reported an unwillingness to recommend them to friends and family, there could be a significant drop off in usage in the coming years, leaving car makers to look elsewhere for fuel economy saving technology.
