Tire Tread/belt problems of the 2005 Chevrolet Silverado 1500

The contact owns a 2005 Chevrolet Silverado 1500. The vehicle has a set of firestone/bridgestone tires, size p265/170/r17. The contact stated that the passenger side front and rear tires have split open just below the tread line. The tires split within one week of each other. He has had one of the tires replaced because the mechanic stated that there was no way that the tires could be repaired. The current mileage, dot number, and vehicle information were unavailable. The failure mileage was 29,000. Updated 08/24/07.

Took my truck to the dealership and was advised my tires were almost bald. . . Had only 16,900+ miles. Dealership replace tires, but not the same type. Yes, same brand, bridgestone dueller a/t. Also dealership did a realignment. Truck never rode the same after the alignment and the new tires. Dealership replaced two on the back after my mechanic noted they were egg shaped. This still did not correct the problem. Tires given to me were bad and the dealership would not correct. Took it to another dealership and their gm rep wrode with me and noted the truck running rough from the tires. Ordered a road force balancing on the tires. This did not work also. Now this dealership will look at my vehicle an further. Truck is still under warranty. Did take it to tire service center and they said the tires are bad and truck needs realignment and also a check of the front end. Advisor stated he could feel every divot in the road, which is not normal. Faxed their report to the local gm rep and he refuses to acknowledge the problem. Neither dealership will even look at the problem. I am afraid for the safety of my family. Can you help me?.
