MICHELIN PILOT SPORT 4 TIRES Complaints

245/35 ZP 19 89Y With only 16,000 miles on this vehicle, the sidewall began to bulge, and then tore, with zero damage to the rim of the wheel, and all air was lost. Luckily it is a run flat tire so it didn't completely deflate, however, I had great concern that with the tear the tire might roll out of the rim on a turn possibly causing an accident or at least a damaged rim. The dealer said they hadn't seen a tear in the sidewall of this tire. A warning light on my dash showed I had lost all air pressure. I have pictures of the tire and the rim showing only damage on the tire.

Certified pre-owned 2021 Tesla Model S delivered on October 21, 2025 with worn Michelin Pilot Sport 4S summer tires (255/35ZR21 front, 295/30ZR21 rear). Tread depth measured approximately 2/32" on the outer tread shoulders of all four tires, below Tesla’s published 5/32" delivery standard. Within the first week of ownership, the vehicle hydroplaned multiple times in wet conditions at normal speeds. Tesla service declined to replace the tires, stating measurements were “taken in the wrong location” and that only the inner grooves count, despite Tesla’s public documentation and national tire safety standards defining tread depth across the full width of the tire. Vehicle was returned in same condition without correction, leaving a continued safety risk from inadequate tread and summer tires unsuited for Ohio’s cold and wet seasonal conditions.

Michelin Pilot Sport 4S T2 295/30R/21 102Y. These tires are engineered by Michelin specifically for a Tesla Model S 2022+ hence the T2 mark. These are a second generation as the previous ones were a T1. Everything is supposed to be factored in by Michelin to cater to the vehicles specifications and needs. I bought a set of 4 of these mentioned tires brand new from Discount Tire. In less 10000 miles and 7 months the sidewalls have completely decoupled from the tread section/rest of the tire. The treadwear itself shows and even smooth normal wear pattern. Discount tire and Michelin are trying to claim this is an alignment issue citing too much camber. This is a false claim. The area of separation is not in the contact patch with the surface of the road. This is a defect in engineering and construction in the tire itself. This calls for a mass recall. I put the trust of my pregnant wife into these tires and she complained to me about a wallowing car ride with a decrease in handling, especially over bumps and on the highway. I could not see an issue. A few days later she informed me of a tire pressure indicator on the dashboard. It indicated tow low rear tires. Upon inspecting the tires I found both sides with a decoupled sidewall. Driver side being far worse than passenger. I immediately drove to Discount tire and the tire pressure sank from 26psi to 8psi in less than 4 miles. This could have proved fatal for my wife and unborn child on the highway. The tire company and the stores dont want to accept accountability. The stores just want to sell more tires. I am having them replaced at a cost of $610 per tire. Thats equaling to almost $3000 spent on tires in 7-8 months. Please investigate this matter. This is a defect. Not wear. The vehicle previously had Falken tires that lasted 24000 miles with smooth and even treadwear. No issues, no defects.

I have a 2021 Tesla Model S Long Range with rear tire size 295 / 30 ZR 21. Both rear tires are worn so bad on the insides that the cords are showing. These tires were purchased and installed by Tesla along with a wheel alignment under 10,000 miles ago. The tires still look like new on the center and outside of the tire so I had no clue this was happening. The only way I became aware was because the low tire pressure warning kept coming on I started losing air slowly over the last month and thought maybe I had a puncture. The damage to the tire isn’t easily visible when just looking under the vehicle. I urge anyone with these tires to check them as it can easily result in a blow out.

295 / 30ZR 21 - My tire failed well before the tread life expired. You can see in the attached images that the tire failed at the meeting point between the tread and the sidewall.

Tires wear less than 1k miles. Deflate, side wall wear, separation, tread wear etc. Have purchased around 8 tires from January 2022 - Present FRONT - 265/35/ZR21 101Y Extra Load REAR - 295/30/ZR21 102Y Extra Load Michelin honored tire failure for side wall separation then denied all other claims. And this is the only tire Tesla has on hand since there is no spare.

Michelin Pilot Sport 4S 295/30 ZR 21 102Y extra load Purchased Oct 2021, estimated 12,000 miles on vehicle and tire. Tire split along inside corner, nearly all the way around the tire. No warning, instant loss of pressure. No significant wear on the outside corner or the tread. Previously happened earlier in the year on the passenger side rear tire.

I believe the tire size is 245 R40 19. The tires interior seams on both rear tires are coming apart. Car has just passed 21K miles, and is driven very carefully. No pothole damage either.

The tire has an excessive and extremely disproportionate amount of wear on the inner part of the tire and sidewall. It is still on the car at this time. The location of the failure is hard to visually notice. My tire losing pressure was the cue something was wrong. It was on the verge of catastrophic failure and only luck prevented this from turning into an accident. This same failure has been reproduced on a large number of Tesla Plaid vehicles equipped with 21” rims and these Michelin tires. It has not been inspected by the manufacturer, police, insurance representatives or others. I will be taking it tomorrow for warranty review from Michelin. There were no symptoms of an impending failure at all. The only warning light that ever showed was a communication error with the sensor that read tire pressure. However, I always checked the pressure manually since that particular sensor was intermittent with its reporting. These tires are rated for 30k and I’m barely over 12k.

Tire sidewall delaminated above the DOT markings. Vehicle purchased new, with only 8500 miles. No tires impacts and tire pressure maintained within recommended PSI (automatically remotely monitored by vehicle). Second rear tire to fail within last 500 miles of driving - failed in exact same way, and exact same place -delaminated above the DOT markings. 295/30ZR21 Michelin Pilot Sport 4 S T2 Acoustic
