CONTINENTAL CROSSCONTACT RX CONTISEAL TIRES Complaints

2 of my rims have cracked the first one around 8,000 miles and the second at around 14,400 miles. I have never cracked a rim before in my life except these 2 within the last few months. I do not take it off-roading and drive on regular roads in Utah primarily. Tire size 275/40R21 however it is the rim that is breaking. I believe these rims are too thin and low profile to handle the weight of the vehicle. Many others online are also experiencing cracked rims. This is also a safety hazard as a rim cracking could cause the tire to fail at high speeds and cause an accident. The included pictures are of the 2 different rims on the same car.

On Friday August 7th, I was driving my 2026 Cadillac OPTIQ Luxury AWD at approximately 25 mph near Byron road in Tracy. While crossing a railroad track under normal driving conditions, both passenger-side tires—the right-front and right-rear—suddenly lost air and sustained sidewall ruptures. I did not strike a pothole, curb, debris, or any other visible object, and no foreign object or tread puncture was found. Both tires were Continental CrossContact RX, size 245/50 R20 105H XL, tubeless and were the original factory-installed tires. The vehicle had approximately 12,850 miles, and the tires had approximately 12,850 miles. Before the incident, there was no tire-pressure warning or indication of a problem, and the tires were maintained at the vehicle manufacturer’s recommended pressure. The near-simultaneous failure of two tires on the same side required an immediate stop and created a serious risk of loss of vehicle control. Photographs show a substantial split in the tire sidewall. There were NO INJURIES and NO OTHER DAMAGE. Both failed tires have been retained and are available for inspection. I am requesting that NHTSA investigate whether these failures indicate a safety defect involving this tire model or its application on the vehicle.

On July 18, 2026, I was driving to work around 0530 am when my rear driver's side tire blew out from the tread sidewall to the rim ruptured, having a catastrophic failure that almost resulted in a crash. The tire only had 18,500 miles without any prior damage or hitting something. Their is a current recall for these tires for the very thing that happened yet my tire batch was not listed as part of the recall. This event was costly and prevented me from working that day. Continental CrossContact 275/40/R21

Under 13k miles the tire developed a bubble on the sidewall. The week is 3824 which is just two weeks prior to the 4024 tire run that was recalled.

The contact owns a 2024 Chevrolet Equinox equipped with Continental Tires, Tire Line: Crosscontact RX, Tire Size: 275/40/R21, DOT Number: IVY03HFMJ0224. The contact stated that while driving at an undisclosed speed, the contact briefly felt violent vibrations coming from the vehicle before the vehicle suddenly veered sharply to the right, slightly leaving the roadway, resulting in damage to the passenger’s side front wheel and tire. No warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed the vehicle with an unstated failure with the tires. The vehicle was repaired, but the failure reoccurred. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 82,045.
