Tire Tread/belt problems of the 1998 Mazda 626

Consumer checked tire before a trip and noticed abnormal wear on both rear tires near the sidewall, the tread was worn all around both tires, upon returning home consumer discovered that there were no more treads on the tires (bridgestone protenza p205/60r15 90h). Nlm.

All the tread on two rear tires vanished after vacation travel at speeds up to 65 mph. There was absolutely no tread left on left rear and right rear tires. Tires on rear normally at 26 psi were not operated below that pressure. Garage mechanic found two rear wheel tie rods bent identically . There was no sign upon inspection that the vehicle had run over anything. There were no scratches or marks under the car to indicate impact with road hazard. I believe the tire wear plus the mfg recommended tire pressure of 26 psi reduced road clearance to the point where the car would bottom out after hitting unrepaired wide cracks in the concrete roadway while traveling at 65 mph. I believe the tire wear was due to defective material in the tires made by bridgestone. I believe the tire wear caused the tie rods to come in contact with the road service causing identical bends in each tie rod, the bent tie rods then would throw the wheels out of alignment and erase the tire treads.
