The front tires are wearing out to an unsafe tread in under 15000 miles due to the suspension in the front of this vehicle. If people are not vigilant the tires become unsafe quickly due to poor engineering on the front end.

I have a 2015 Toyota Sienna LE that I purchased new from the dealer. The original Michelin tires had excessive wear after less than 2yrs and ~28K miles. I replaced these with Continental tires(rated for 70K miles) and after 2years and at ~63K on the vehicle miles I had to replace those with General Altimax (rated for 75K miles). Each time tires were replaced it received and alignment. I now need to replace the third set of tires at ~88k for set number four. Additionally I had to replace the Rank and Pinion (Complete unit), both tie rods and both suspension control arms and ball joint assembly and a wheel alignment. Can is adult driven mostly in town but has one long road trip on it (6K miles). This will be the fourth set of tires on a vehicle with less than 100K miles along with 5-6 alignments. All tires have been maintained and rotated. This has to be a vehicle defect as I have multiple tire manufactures, all rated for more than double the tire life I'm getting. I have $2000 in tires so far (not counting the originals) $1250 in replacing the front end components noted and now have to spend another $1k on tires.

The van is too heavy for the rated tires, and wears the toes out so dangerously that risk of premature blowout is imminent. Just hit 100K miles on my 2015 AWD Sienna. 1st set of tires lasted 35K miles with run flats, but was down to the steel mesh. Next set was kelley that lasted 32K without runflats, 3rd set was Goodyear that lasted 32K. Ready for set number 4 now, so average of ~32K per pair, each of them had a 50K mile warranty minimum. All 4 sets were toe worn down to steel belt radial and had been rotated properly.

The contact owns a 2015 Toyota Sienna. The contact stated that the rear driver's side wheel was fractured in several places. The contact stated that the wheel/rim was the original equipment. The contact was concerned that the integrity of the wheel may be compromised. The vehicle was not taken to be diagnosed or repaired. A dealer was not contacted. The manufacturer was informed of the failure. The approximate failure mileage was 58,410.

Uneven wear tires. I bought a used Toyota Sienna last year Jan of 2018 with brand new sets of tire. After 20K miles, it was down to 3mm and have it replace. I was searching forums and found out that everybody has the same problem as me. It was a bad engineering of the van. I did the alignment after I got the van but I still experienced the uneven wear. I also balanced the tires every time I feel my steering wheel shaking. There must be a defect on the van as I am not alone with this problem. Two of my tires was bald on the outer side. Most people that owns Sienna said that every 20K miles, they have to replace their tires and I agree with them.

Recently obtained ~60K service at dealership. Advised that Michelin premiere A/S tires purchased just 15K miles previously were measured at 4/32" in the front and 5/32" in the rear and should be replaced. Severe scalloping observed on the outside edge of the tires. The set of four tires were purchased a one of the large, us, wholesale club stores. The Toyota service writer stated that my wife that such stores carry inferior quality tires, though they may be branded and labeled the same as the models carried by Toyota. I contacted Michelin about this claim and was told that it is false. The tires on this vehicle have been rotated roughly every 5000 miles or so during schedule prepaid maintenance on the vehicle. There was a mechanical issue noise from the front end in March of 2018, just after the new tires were installed. Toyota replace the front-right axle shaft, which did not resolve the problem. Ultimately, both front wheel bearings were replaced. Toyota performed the work under warranty and stated that an alignment was not necessary. It could be entirely coincidental, or the axle and bearing work could have every thing to do with the early demise of an $800 set of tires. However, after much research online, it seems that I am not the only one who has experience the issue with a set of high quality tires lasting 15 to 25K miles, though warranted for much greater ranges in the area of 60 to 70K. It appears that there are many people who have had issues with early abnormal tire wear. Toyota in most cases blames the driver, or the tire manufacturer. It would seem clear to me that the problem is with the vehicle. Toyota must be responsible for purchasing and/or replacing tires and performing necessary alignment or suspension maintenance to resolve the issue.

I am on my 3rd set of tires (including original) in a 3 year old van. My second set was purchased at 34449 miles on 12/2/16. I purchased 75000 tires, as of today I have 78850 miles on the van, so I used only 44401 miles of 75000 miles tires. In September of 2018, I noticed a strange wobbling in the rear passenger back of the van. I took it to our mechanic at reese's garage and I told me my tire was about to blow and I needed new tires. He suggested I don't drive the van, as it was "unsafe". took it to another garage (barnes service center) and was told the same thing. I was also told this is a common problem with Sienna. I did some research and learned that this is indeed a problem!! I contacted the executive office of Toyota, and they indicated that other factors must be considered. My alignment was good, my shocks/struts are good, I don't drive a lot, just to & from my kids school, sporting events, and I don't drive like I'm in the daytona 500. There was excuse after excuse. This is the second time I have been told that my van is "unsafe" and almost had 2 blow outs. I put my concerns on social media and I learned there are many Sienna owners complaining about tires wearing too quickly. Toyota needs to fix the problem before someone gets hurt. I don't feel safe driving my children in the van.

Bought vehicle new, live in Florida with no potholes, etc. The van is extremely hard on tires, first set of Michelin primacy mxv4 tires lasted to 26,500 and were shot. Replacement Michelin premier ltx tires are shot in 20,000 miles. Both of these Michelin tires were supposed to last 60,000 miles each. Never any damage to the vehicle, I am the only driver, but I just spent close to $800 at an alignment shop getting camber kits and shims installed and one new front strut all trying to get the vehicle alignment into factory specs. Again, never any damage to the vehicle and all tires wore out relatively evenly, just way too prematurely. First problem in my opinion is that all vehicles should have alignment adjustment ability built in, there should not be need for camber bolt kits and shims for the rear axle. Next problem is this excessive tire wear on Toyota Sienna's is clearly documented all over the internet, so this is not an isolated problem, but a wide spread Toyota problem. Toyota should resolve this for their customers.

I have a brand new Toyota Sienna and the tires seem to start showing sign of wearing off in 6 months, as if it has alignment issues or something. The car does not pull to one side or anything. The dealership told me that it could be the tire pressure that needs to be kept up and they said that the tire pressure indicator is not good enough to make sure if the pressure is good" also they told me that the tires these days are softer so they don't last as long" this all seems a little hard for me to believe. Oem tire warranty up to 60K but not last long. Just change new sets of tire with alignment. Toyota engineering needs to address this issue

Vehicle wears through tires at an alarming rate (approximately every 15,000 miles). Vehicle has been aligned prior to new tire installation each time; however, tires wear abnormally fast. Driving was under normal conditions, highway and local streets. Several tire manufactures were tried, but all tire wear results were the same.

- Eden, NY, USA

Excessive tire wear on front outside tires. Wheels/tires have been balanced and rotated their whole life. Alignment of vehicle is good. Tires have been constantly monitored to remain the recommended pressure of 36 psi. Lifespan of tires is supposed to be 60000-80000 miles. Vehicle is currently at 26000, and tires are shot. This is clearly a flawed design. Vehicle is adult driven.

We bought our 2015 Toyota Sienna le all-wheel drive in February 2015. At 16,000 miles, we took it in for maintenance because it was shaking during braking. We were informed that the rotors were warped and needing replaced. They were replaced. At 22,000 miles, the wheel inflation signal keeps coming on every other day after refilling air into all tires; we inspected the tires and found that the two rear tires were very worn on the inner side of the tires. We took it to sheehy Toyota of fredericksburg again for maintenance. We were told that it needed alignment and 4 new tires. We were also told that the tires would not be covered because factory tires from dealerships were not covered under warranty. But the main concern is that, at just 22,000, there's already rotor issues and alignment issues from just normal driving. Never drove in gravel or rough roads. I believe there's an issue with the 2015 Sienna line of vans, regards to brake rotors and alignment problems. It's a big saftey concern for me and my family. And it's disappointing to hear that Toyota will not cover alignment issues, though the vehicle is still so new. It could have been tragic if we didn't catch the worn tires this soon. For the record, we had never missed an oil change or scheduled routine maintenance.
