Flat tires suck, but apparently
that’s not enough to keep some owners of the Toyota Sienna minivan from complaining about wear problems with the
Dunlop run-flat tires found on models equipped with 17” wheels. In fact, a group of owners have actually gone so
far as to file a class-action lawsuit against Toyota and Dunlop, alledging that the tire wear issue consitutes a
product defect. What’s not made clear is the expected life of a normal set of tires on the same vehicle;
obviously, issues with suspension geometry, alignment, or a driver that has mistaken the vehicle for a sports car could
all contribute to greatly reduced tire life. Admittedly, though, it would not be fun to shell out over a grand every
10-20,000 miles or so - at least not on the family’s people mover.
