| Description of the problem | All four dunlop sp sport 4000t dsst run-flat tires on my 2004 toyota sienna xle awd are completely worn after 20,000 miles and need to be replaced immediately according to the toyota and dunlop dealers. These tires were the original equipment on the minivan. Dunlop informed me that these tires had no mileage rating. I have seen a number of consumer complaints regarding this tire (see comments on www. Tirerack. Com). I have spoken with toyota north america and was told they do not warranty tires and this is not their problem. I believe it is a serious design flaw to put this particular tire on a minivan in the first place. I have been told by dunlop and a tire dealer that this is a high performance, short life tire. This minivan does not come equipped with a spare tire and there is no place for a spare tire in it, which is likely why toyota chose to equip it with a run-flat tire. Consumers have very limited alternatives for replacing this tire and they are extremely expensive. Accordingly, in my view, toyota should have (i) selected a more durable tire for this vehicle (ii) clearly disclosed the tires expected useful life to consumers or (iii) included a spare tire and well in the vehicle. I view this situation as potentially very dangerous because drivers may not be checking these tires for wear at 15,000 miles and could easily have tire failure while driving. *jb |
