| Description of the problem | With our 2004 toyota sienna minivan, we have had several problems with the run-flat tires installed on the vehicle as original equipment. These dunlop run-flat tires are standard on the all-wheel-drive versions of the 2004 and 2005 sienna. The tires have been prone to puncture (two semi-delfations in the past 6 months) and the tires do not wear properly. As a result, we are forced to replace them at $300 a piece with only 12,000 miles on them and after they were properly rotated and maintained during their short life. A quick search on the internet confirms that these problems are rampant on the 2004 and 2005 siennas with these run-flat tires. The toyota dealer has admitted that this is a big problem with these cars and has offered to pay for only 2 of the 4 new tires. To exacerbate the problem, siennas with run-flat tires are not equipped with any spare tire because the run-flats are supposed to allow you to drive the car until you can have the flat fixed. Two problems emerge from this -- (1) if your run-flat tire fails completely (there are reports of this on the internet), you are stuck with no spare; and (2) if you can still drive on the flat tire, there are few if any repair shops outside of major metropolitan areas that can fix these run-flats. |
