I was driving in August and could hear something banging on the underside of my van, I would stop and it would go away because the tread would fall on road and then start a day later with more tread coming off. It was the tread coming off of my tires but didn't know that at the time and getting caught on the underside of my van. This went on for 2 weeks. My tire sensor never came on. I drove to Ohio on I-75 October 21, 2012 and my front 2 tires blew out at the same time - br 001522 tires. A big slash in one tire a small hole in another. I pull over and see a lot of the tread is completely off of both tires. I get to a tire store and they said it look like the alignment caused the wear. I replaced all 4 tires and have the tire co put the 2 in my back van. I go to belle tire to get a refund for my tires with 29,000 miles on 65,000 wear tires. They said they would call Bridgestone. Bridgestone denied my case for a refund. I got an alignment 11/14/2012 and it shows my alignment was ok a little off but would never have caused that kind of wear with tread just coming off both tires at the same time - they are defective tires. The white spikes were showing on both tires - the tread came off completely on both tires around the edges.

Failure of sidewalls of two Bridgestone insignia SE200 215/65R16 tires at 5693 miles of normal driving conditions on 2006 Toyota Sienna van-dot # ob6ve224711 located on tire sidewall. Tires sold by monro shop # 190 in christianburg, va. Same tire brand, model and size replaced at shop #349 in cheshire, ct at cost of road hazard coverage contract at cost of $87. 80 to cover all four tires. I am very concerned that the other two tires purchased at the same time with the same dot designations may also develop sidewall bulges and be the cause of a serious accident. Is there a manufacturing defect on this tire that should be looked into?

I had a failure of a Goodyear integrity tire with only 29,000 miles it. It had uneven tread wear and the wire strands poking out from a broken steel belt. This tire was on the right rear position of my 2006 Toyota Sienna this defective tire caused my Sienna to wobble violently with speeds above 35mph. This violent wobble also caused abnormal tread wear on the inside surface of all four tires on the vehicle. This tire was one of two Goodyear integrity tires I purchased from fox river tire and supply on 5/10/08, when the vehicle mileage was 21,059 miles. These two tires were on the front axle until I purchased two more Goodyear integrity tires at abe and doc" S service, Inc. On 7/16/09 at a mileage of 35,247. At this time the subject tire was moved to right rear position. When the mileage on the 2006 Sienna reached 50,793 the vehicle started wobbling violently over 35 mph. The vehicle was taken to abe and doc? S service, Inc. To diagnose the problem. I was told that improper wheel alignment had caused all the tires to wear on the inside surface and that wire strands were exposed on the right rear tire. I asked if the tire had a ?pro-rated " warranty and was told, no! it was suggested I purchase two new Goodyear integrity tires at $165 each and a wheel alignment. Instead I took the Sienna to St. Charles Toyota for service, where I purchased two Michelin tires and a wheel alignment. The Toyota technician stated the alignment was good (receipt and computer alignment report attached). The Toyota dealer advised us to report this defect to Goodyear.

Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6) I purchased four Firestone FR710 tires on August 27, 2009 from a local Firestone dealer for my 2006 Toyota Sienna. Recently we noticed that the front right tire's tread was delaminating all around the perimeter of the tire where the tread meets the sidewall. In some places there was 1/2" of separation. Upon closer inspection it was found that two of the other tires were also starting to separate. This was evident due to small hairline separations running around the perimeter of the tires in the same region as the worst tire. These tires were all made within a week of each other with date codes of 1909 and 2009 (19th and 20th week of 2009). The dot number is W56V710. The VIN of the vehicle is [xxx]. the mileage at purchase was 49,328 and the current mileage is 61,491. Photos of the tires are available.

I want to report what I believe to be a safety/product defect with the following tire: Dunlop P225/60R17, 98T, M+S, sp4000T, dsst ctt this is a so-called run-flat tire (installed approximately 12,000 miles ago) per original equipment specifications on my 2006 Toyota Sienna AWD minivan. Within the past six weeks, (3) of these tires ruptured so badly that they had to be replaced. With the first blowout, I surmised that the problem might be due to Michigan's notorious road pot holes. I was even willing to concede this might still be the reason after the second blowout. But when the third occurred two days ago, I concluded that a serious defect was at fault. Note that the tires were properly-inflated according to the sticker on the driver's door jam sticker (35 psi). Though it was possible to drive slowly on these ruptured tires to a dealer for replacement, the cost for new ones is very high (~$250 each, installed). As a consequence'after the third blowout'I installed (4) conventional tires. My total tire replacement costs are now > $1000. I would appreciate your contacting me about the status of this problem.

I contacted Toyota customer service on 01/16/2007 (file #200701190685) about vehicle defects of my newly purchased 2006 Toyota Sienna but didn't receive any response except the notice of reception of my complain. Problem: Run on low tire pressure (22 psi instead of indicated 35 psi) for one year from the time I purchased this vehicle from the dealer till that I found out the problem. Reason: The dealer (universal Toyota san antonio) admitted that they needed to lower the tire pressure of the vehicle during transportation from factory to dealership but someone forgot to set it back before it was handed out to customer. The maintenance dealership (cavender san antonio) also didn't do their job to check the tire pressure until one year later I asked them to do so. Toyota solution for this problem: The manager of cavender san antonio promised to give me a free tank of gas and a free maintenance next time. I accepted. However, I asked the dealership to replace the four tires because they were damaged, but they didn't agree, arguing that even under low pressure, these tires should be fine. Consequences: Three of four tires on this vehicle were deflated on highway in less than one year (3/22/2008, 9/6/2008, 3/20/2009). The last tire deflation was terrible and almost caused five lives on the vehicle because it was sudden and the vehicle was lost of control. The tire pressure alert didn't even light up at the beginning. After this accident, I decided that I can't take any chance with these tires and replaced all four tires. I kept all these receipts. My requests: Compensate the cost of these tires, the damage to my vehicle and Toyota's neglect for so long until it became a big problem.

Toyota equips and sells their Sienna AWD vans with dunlop sp sport 4000 P225/60R17 dsst run flat tires and fails to inform you that you will be lucky to get 20-25,000 miles on the tires. I had my van serviced and tires rotated every 5,000 miles and not once was I informed that my tires were wearing out. At 25K I had to get 4 new tires. Toyota did pay for 2 of the 4 but it still cost me $558. My van was manufactured after 09/05 so I was not eligible for total replacement per a class action law suite.

Run flat tires needing replacement only after 2 years of owning the car. 2 blowouts on the freeway due to no direct tire pressure sensor to alert us of the flat tire. The light only goes on after the tire is blown. The first blow out, I drove it directly to the dealer. Total cost of replacement $350 for tire. I then had problems with the "indirect" tire sensor light coming on. I called the dealer back, he told me to ignore the light because the cold outside was causing it to go on. I drove it back anyway, they checked the tire pressure, put some more air in and sent me home with my sensor light still lit. I took it back to the dealer a few weeks later, they said it was a leaky valve. They replaced the valve, filled the tire with air and sent me home. Less than 5 days later, another blowout on the freeway. I drove it to the nearest tire store. They could not do the repair because the tire would ruin their machine. "it's harder to break down" and take off. I was sent to another tire store. They were able to remove the tire and replace them with regular tires. Now, I don't have run flats anymore, but I don't have the excessive cost to keep replacing these expensive tires. The dealer told me at the time of the purchase that it was a "dream" for mom's transporting kids because I wouldn't have to change to a spare if the tire went flat. That the care was safer than safe. The manager of the service department also told me I was lucky that I got 40,000 miles out of them. Both tires blew out on the freeway, I rolled the car in at 25 miles per hour, on the rim, with my kids in the car. I did it safely with my driving, not because of the run-flat tires. I will never purchase another car with run-flat tires. They didn't tell me how expensive they were to replace and that I would need to replace them so frequently. Also that the tire sensor is indirect. I didn't even know when the tires were just getting low, only when completely flat.

Ever since I bought this Sienna 2006, I have noticed both of my back dunlop tires are leaking air frequently starting on Feb 2008. The mileage as of today is only 5400. The right side of the back tire popped and I have to replaced with the Michelin. As for the left side, every week, it dropped to 20psi. I have to pump it back up to 35-40psi every week. Took it to the dealer, no holes or any problem found on the dunlop. They refused to replace the tire. I ask them why it didn't happen to the front tire then, why only the back tires? I told them it must be the manufacturer problem and they have to replace. No comments from them and they said I have to purchase a new one to replace it. Stupid idiot solution from them.
