Dunlop SP Sportmaxx DSST Defective

Hello,

I purchased a new 2015 640i equipped with Dunlop Sportmaxx GT DSST run flat tires front and back. During recent roadtrip one of the tires blew out. As unsual, Goodyear/Dunlop first blamed others when I first tried to exercise the warranty.

I would like the forum's opinion on this tire. It appears there are several complaints on blowout of this tire at NHTSA but no recalls. I may or may not replace with the same tires.



Best, Ben

I would deny warranty on a blowout of a 'name brand' tire. I believe that it must have been sorely abused.

How many miles?

I just had to replace one of these tires on my car last week. (16,000 mi). I noticed one day that the tire had a slit from the edge of the wheel to the edge of the tread. Looked like someone took a razor blade and cut it. Not sure how deep it was, also not sure how long it was there. Prorated tire warranty claim denied. They claimed curb rash, though there was no damage to the wheel. Tire was 60% worn so I didn't bother to fight any more. They did give a discount on the tire though.

Other than that the tires have performed well.

These tires are not abused. The break is below the wheel rim. Already got Goodyear to admit it was a manufacturing fault. Tires are deemed 28% worn.

Now working on getting Goodyear/Dunlop to honor the warranty without buying their products. Tie-ins for warranties are against the law. Still takes work. Terrible reviews on Tirerack.com as well as NHTSA website. Wonder why BMW chose to put these tires on.
