The driver was unsure of the vehicle's speed at the time of the failure. The vehicle was taken to a Toyota dealer. The dealer diagnosed the driver's front and rear tires failed.

Toyota has been placing dunlop SP40's on their Sienna van's at least from 2000 to 2003. They are extremely unsafe and are prone to premature wear (less than half of their 80,000 kilometers. Please refer to 1010tires.com under reviews for that tire (very numerous). My tires were worn over 75% at 33000kms. Even prior to wear they are extremely unreliable esp. In the snow and rain---I had spun out on a straight stretch of snow covered highway several times entering oncoming traffic the winter previous. The Sienna has a high safety rating but it is in fact an unsafe/hazardous vehicle by virtue of the tires placed upon it. I believe Toyota is aware of the problem but will not admit any responsibility. Through much argument, Goodyear has replaced the tires with new ones giving me 50% off (I shouldn't have to pay anything because I have been placed in a position of purchasing new tires when I should not have to for the next 3-4 years). Toyota refuses to compensate me the other 50% and will not admit to this unsafe (but no doubt profitable) relationship that it has with dunlop/Goodyear. There is no doubt in my mind that these tires are substandard if not defective and I am upset that dunlop/Goodyear and Toyota had placed my family in danger because of their arrangement. I had bought the van because my wife and I had a new baby and had trusted the safety rating boasted by Toyota (unaware that the safety was compromised by the tires that they choose to utilize on the van).

Driving South on I-15 North of las vegas, tire tread on passenger side rear wheel separated without warning. It was a hot day (around 110 degrees) and the highway speed there is 75 M.P.H. the tread flew up and smashed the side window of the Sienna minivan, tore off part of the side fender and damaged the sliding door. The tires had been well maintained and had been inpected within the previous month at the Toyota dealer. Nonetheless, Firestone has refused to compensate us for the monetary loss and has tried to shift the blame to us, saying there was proof that the tire had been run low, etc. (we had to drive on the tire after we lost the tread as we were in a remote area. Since there was still air in the tire I drove slowly to where we could get help.) thus I have argued that the wear found by their "engineers" was due to driving on a treadless tire which was losing air. I have requested Firestone to send us back the damaged tire. The damage repair bill was $1780, plus the cost of the rental car etc.
