I have a 2006 Toyota Sienna xle AWD minivan which was seen 10/17/07 for tire replacement (dunlop 4000 dsst run flats). I have owned this care for 1 year and 2 weeks and have only 14,900 miles on it. Recommended service has been done at the dealership twice since I've owned the car, including tire rotation...once in February and once at the end of July. The car was driven only under normal road conditions and air pressures checked every 2 weeks. I am two weeks past 1 yr. Warranty and even though preexisting wear was "missed" by service dealer in late July, I am being charged for replacement. Toyota aware or previous problems with these tires, including class action law suit, yet continued to put them on cars. My tread wear was determined to be uneven with 0 depth on the inside tread of left front, posing a safety hazard and creating an unsafe driving condition. Report also indicates wear on edges and cupping evident on all other tires (according to the dealer, my VIN number did not match up with the "service bulletin" and I was charged for the installation of these tires and a wheel alignment) an attempt to contact Toyota customer care while the car was in the shop was unresolved as customer care never returned my call. Run flats were supposed to be a safety feature on my AWD, instead they have become a safety hazard. One does not carry a spare, and in fact there is no room for one in this Sienna. You would not expect to need 4 new tires at <15,000 miles!

Dunlop ST4000 tires are worn out at 20,500 highway miles. Serious problem. This is a really big issue, as I have seen all the complaints on many internet sites. I am very disappointed with these tires. The car is less than a year old and I have to spend $1000 plus on new tires"????" I went to my Toyota dealer and they told me that there is nothing they can do and that I will have to pay for 4 new tires. I can't buy regular tires because there is no room for a spare tire anywhere. This is insane. I will have to think twice before buying another Toyota. I have been a Toyota fan since I could remember; this has really changed my perspective of this company.
