2016 Jeep Grand Cherokee Tires Problems

All four of your tires have developed cracks that go around the entire circumference of each tire, possibly due to sidewalk defects in the Cooper Evolution H/T tires. These cracks could compromise the tire's structural integrity and create a safety risk. You should have the tires inspected by a professional and likely replaced if the cracks are significant.

Tires: Pirelli 285/40R22. Tires failed: Front passenger + Both -Driver/Passenger tires. Failures did not occur concurrently. I am writing to report significant issues with the Pirelli tires on my vehicle, raising serious safety concerns. (Usage, two tires - 11 months / 1 tire - 4 months) Firstly, the front passenger tire has developed noticeable bumps on the sidewall near the rim. Notably, these tires have never encountered foreign objects or rough terrain that could have caused this damage. The bulges indicate potential internal damage, compromising the tire's structural integrity and posing a risk while driving. Additionally, the passenger rear tire suffered a catastrophic blowout at 65 mph on Interstate 75. Examination revealed a 10-inch strip had detached from the tire's inner layer. This sudden failure occurred without warning and could have resulted in a severe loss of control, endangering my safety and that of other road users. Similarly, the driver rear tire also blew out at 65 mph on Interstate 10 due to a failed section measuring approximately 6 inches along the contact area. These incidents raise critical concerns about the reliability of these tires, especially at highway speeds. Following these events, my technicians inspected the vehicle and found no other underlying issues, raising further questions about the quality and durability of these tires. I urge you to investigate thoroughly to prevent risks for other customers relying on your products. Thank you for your attention to this issue.
