Consumers Less Satisfied with Run-Flat Tires

U.S. consumers report fewer problems with conventional tires than run-flat alternatives, according to a poll by J.D. Power and Associates about satisfaction with original equipment tires.

The survey finds consumers also wary about the grip and durability of low-rolling-resistance tires, which help improve fuel economy. It suggests tiremakers do a better job of educating consumers about the benefits of such tires.

Run-flats, which eliminate the need for a spare tire and jack, also can contribute to better fuel efficiency. But such tires wear out after an average of only 16,500 miles, according to the report. That compares with about 22,600 miles for conventional tires.

Power surveyed consumers about their experiences within the first two years of new-car ownership. Among this year's respondents, 31% of those whose cars have run-flats reported replacing at least one tire. That compares with 19% of respondents whose vehicles were shod with conventional tires.

Consumers also complain that run-flats, which cannot be repaired, often must be replaced in pairs. Power says owners of performance cars are half as likely to "definitely" recommend run-flats to others as are those whose cars ride on conventional tires.
