I filed a complaint 10/18/2018; however, the complaint was for 2 of the 4 tires. Today's complaint is for the remaining 2 tires which had manufacturer defect per the shop. Please note these are coopertire,cs5 not cs4.t there's not an option for "cs5 "t so like others I'm using the closet which is "cs4 t". My van starting shaking (at this point I have two new tires on 4/18 (cooper cs5 -t) and the other two tires are also cooper cs5 -t, but purchased 1/2016, 80k mile "wear out warranty" I've put 7k on the two "new" tires & the other two have 48k (22k left). The steering wheel shakes, people shake, I stop driving it anywhere that will require me going over 35mph.shaking isn't even the word for it when over 35 MPH. I can't get anywhere on my 35mph for 1.5 weeks.. Not fun with 4 kids to run to sports school & events. I get the van in finally on thursday, 10/18/2018. I get a call from the shop to tell me there is a "manufacturer defect" on the two older cooper tires. That defect which is typed on my rcpt is "found that the tire had a ply separation causing the vibration." so I looked it up, not knowing exactly the jargon used "tire separation is one of the most dangerous things that can happen to a tire, and can put the driver of the vehicle and everyone else around at risk. A separation can lead to a tire blowout, which in turn can lead to one of these even more serious accidents. Head-on collisions. Rollover accidents. Road run-offs. Side impact incidents. And, more. Often times, the injuries sustained from these accidents are severe, if not deadly." I'm a meticulous record keeper and do regular maintenance on my vehicles. The tires went on 1/2016. Rotated 1/11/2017, 5/17/2017, 3/2018, 4/2018,10/2018. Out come same as last. 2 new tires I pay for, no options, so same brand on again. In 2016 I spent $675 on 4 new tires, they should have 22k left of wear. Instead in total I've paid $106 to have the brand tire on it.toyota said all 4 tires were a problem 2/2018, denied

I bought a 2006 toyota sienna in december.,2006, the following september while coming back from vacation I had a blowout on my factory installed bridgestone tire. I do not necessarily believe the problem is the tires, rather, the alloy wheels, as the tire pressure light goes on frequently, the wheels have been peeling since I bought the vehicle new, when I inquired about a problem with the alloy wheels toyota blew me off.I know many are having the same issue with their alloy wheels. I think the alloy wheels are defective causing problems in tire pressure and ultimately causing blowouts. The bubbling and peeling just makes it apparent cosmetically that there is a bigger problem. Please investigate.

The vehicle has rear alignment issues. The camber which are set at a negative value from factory caused an excessive wear on the interior outer lining of my run-flat tires. While on a family trip, the tire exploded on the interior side in traffic. Taking the vehicle to the toyota dealer for new tires and inspection right after the incident, they returned my car with the new rear tire stating it is in need of a proper rear alignment. Upon research and taking my vehicle to numerous local tire shop/garage for opinion, they told me that the rear wheels cannot be adjusted or aligned due to the way it was built. However, toyota insisted that the rear wheels can be aligned, so we did allow them to do a 4-wheel alignment. After receiving my vehicle back,it can be recognize that the rear tires are definitely not "straight" at all, by observation the bottom of the wheel is leaning toward the car. My concern regarding this issue is that many people with 4-wheels drive sienna have the same problem with their rear wheel alignment. If this is an issue that toyota do not fix, wouldn't that mean that we or any 4-wheels drive sienna owners are prone to more accidents and must keep getting new rear tires?

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.

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.
