Tire Tread/belt problems of the 2000 Mercury Mountaineer

My 2000 Mountaineer had 17,000 when purchased. I had noticed the dealer had just put new 235/75r15 goodyear wrangler r/ts on it. I was not suspicious but should have been. Ever since purchased I have had a vibration in the front end and my front tires have worn on the inside al the way down to a unsafe tread depth within 10,000 miles. The dealer alligned the front and checked for front end problems two days after purchase. At that time they found it was out but claimed they had just alligned it three days before also. At around 30,000 miles I had to replace the front tires because they were unsafe. I took them to the dealer and the gm told me that it was normal tire wear. I know quite a bit about cars but he did not know that. At that time they checked the front end allignment again and check for problems again and found nothing. A few weeks later the vbration got worse so I jacked it up myself and found that the one a-arm nut was loose. I tightend it and drove back to the dealerand showed one of their mechanics the problem. It had loosend up again already so he tightend all the a-arm nuts. Ileft and within 10 miles one was loose again. I went back to the dealer and told them to replace all the a-arm bolts and nuts. I have since went through 2 more sets of front tires ,so that is 4 sets of tires in 63,000 miles, but they say there is nothing wrong . Anyone having these same uneven tire wear and vibration problems please contact me. 865-776-2246 brian.

The treads are coming apart.

Firestone wilderness at tires were included in recall 00t005, however consumer replaced tires after hearing nothing from firestone and requests a reimbursement for all 5 tires.

Lost complete control of vehicle when 2 right-side tires blew out off rims and left me to drive on only the rims. ( dot number: tire size: p255/70r16 ).

Whil driving approximately 65 mph on wet pavement, the left rear tire blew out and when I was able to pull to the side of the road, the tire was shredded off of the rim. This matches the description of the problem involved in the current firestone recall. The vehicle is owned by Ford motor company. I am a Ford motor company employee who leases the vehicle from the company. ( dot number: tire size: p235/75r15 ).

Vehicle experienced a right rear blowout(tire size p235/75r15/dot # unavailable) while traveling at 45 mph in a 2000 Mercury Mountaineer, tire was the original equipment, no injuries were reported. Replacement was made at dealer, and tire not available for analysis. Please provide any further details. Firestone atx p235/75/r15.
