Tire Sidewall problems of the 2000 Jeep Grand Cherokee

The contact owns a 2000 Jeep Grand Cherokee equipped with cooper tires, tire line: discoverer a/t, tire size: 225/75r17, and dot number: ut2y1df1515. The contact stated that all four tires had cracks along the sidewall. The tire dealer was made aware of the failure and advised the contact to file a complaint with the manufacturer and the NHTSA hotline. The tires were not replaced. The manufacturer was not made aware of the failure. The failure mileage was approximately 170,000.

Without warning, the front passenger side tire blew while driving. The consumer stated two other tires were leaking air because the sidewalls were defective. The consumer was constantly putting air in them.

Tire failed at sidewall for unknown reason. No road hazard damage found. No tread damage found. Tire jack failed twice, resulting in near-injury to state trooper assisting us. Tire jack is insufficient for weight, height of Jeep gr. Cherokee. I had same tire jack failure on my 1997 Jeep gr. Cherokee and reported it to Chrysler then (via the dealer).
