Tire Tread/belt problems of the 1996 Jeep Grand Cherokee

The contact owns a 1996 Jeep Grand Cherokee equipped with goodyear wrangler tires, size: p235/75r15. While the vehicle was being serviced, the technician stated that the tire could not be rotated because of cracks in all four tires. The manufacturer was notified of the failure. The approximate tire and vehicle failure mileage was 19,000. The dot number was not available.

Was driving on i35w heading south in tarrent county texas. Was doing posted speed of 70m/hr and had the tread come off of the back right tire. Vehicle was in 2 wheel drive at this time. Lost control for a breif instant. Got stoped safely, and put on spare tire. Went to dealer to have vehicle checked 2 days later when open. Found alinment was now off. Had allinment fixed. Went to firestone dealer in denton, TX and requested help. Offered to replace tire with a new one. Answer was not acceptable, because replacing one tire would give poor handiling characteristics. Tried e-mailing firestone, got a reply about the recal of the tires that did not afect me. Tried calling firestone, said they could not help. I do not feal safe driving my vehicle with firestones on it any longer and am wishing to try to get a different brand of tires to replace them. I can provide pictures of the damaged tire, and e-mail them upon request. (dot number: 8xhl tiresize: p23575r15).

Tread separated while driving on interstate. Tire held air pressure. Wife (lori) was able to control vehicle and pull over safely. Blackwall was facing out( dot number: w2hl 1py tire size: p235/75r15 ).

Hub casting error, resulting in grinding/knocking noise at slow speed; also, belt separation in three of four original tires.
