| Description of the problem | 2006 toyota sienna w/run flat tires showed significant premature tire wear. All service maintained with toyota dealership and up to date. Determined that at 19. 400 miles the wear showed tire belt creating a safety hazard unknown to the driver/owner until normal service visit. The vin was outside the effected vin list associated with supplemental tire warranty coverage sponsored by toyota related to identical problems with previous awd siennas. Toyota refused assistance in replacing tires. Dunlop provided prorate of 48% for replacement. Tires were viewed as unsafe based on premature wear that would not be noticeable to owner/driver without understanding the problems with run flats. Toyota refused any support since vin was 5000 outside the effectivity of the supplemental warranty. Failure of tire due to premature wear could result in loss of control of the vehicle, and ultimtaely loss of life. Research via internet revealed other premature wear problems that were also outside the vin effectivity list assosciated with the suppllemental warranty. Only time when a tire failure will result in an accident and potentially loss of life.*ak |
