2003 Toyota Sienna XLE AWD review from North America

Poor performance of run-flat tires.

The run-flat tires are hard to find and very, very expensive to replace. The tires on my 2004 Sienna needed to be replaced after just 10 months and 15,000 miles due to uneven wear. The new tires cost $250 each, with a total cost of $1,200 to have all 4 tires replaced on the vehicle. Dunlap, the tire manufacturer, does not offer any mileage warranty on the tires. Toyota disclaims any responsibility for tire-related issues. This means that tire maintenance will cost $100/month for this vehicle. Moreover, it will take a couple of weeks for the new tires to arrive because they are on back order. Since there is no spare tire for this vehicle, the long wait for replacement tires is a serious issue in an emergency replacement situation. The problem with uneven wear on all 4 tires leads me to wonder whether the all-wheel drive system on the vehicle is properly mated with the run-flat tires.
