Hello, I have a Ford F 250 Super Duty king ranch 4X4 diesel that my wife and I always wanted. We bought from a used car/truck lot. The rims and tires are brand new as is alignment was also had done to fix the problem right out of the gate but it didn't.. when the truck gets to 44 miles an hour and up to 50 mph my F 250 hops land I don't know if its from the front or back but I think its happening in the front the way it feels on the steering wheel.. my truck steering wheel does not move back and forth like the tires are wiggling right and left, it is more like when you have a bad rim or uneven tire hop, like when I was a kid and couldn't afford tires and bought some used ones and get a bum tire in the set or maybe a rims that I had traded for and one was bad.. we love this F 250 and have put a lot of money into it, not knowing anything about diesel trucks, only loving the sound and power of them so the problems the dealership failed to point out or mention to us we have had all fixed properly and this hop or bounce that my F 250 is experiencing is really a worry to us seeing how we bought it to pull a travel trailer we purchased to explore this great U.S.a. so we will be constantly driving it attached to the trailer or not. I have replaced rims, tires and had an alignment as stated before and would really like to solve this problem which if you googled it and seeing alot ofl others experiencing this same problem and some even life threatening which worries me also if whatever the problem is, causes something to break or happen. I thank you for your time and concerns to remedy this safety hazard on Ford Super Duty trucks.. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I own a 06 F250 sd, and everytime I hit a small bump in the road when doing 65+ speed I get extreme shaking. I got a letter from Ford recently about the shimmy thing, and I tried what they said and adjusted the tire pressure but I found this does not work I still get it. It said in the letter that you all approved this but I don't see how you could let such and unsafe thing still be on the roads.

I purchased the tires (4) in April 2008 through a wholesaler friend. I had the tires install and liked them. On August 23, 2008 I was on my way home and about 6 or 7 mile from the house I felt a vibration in the front of the truck (06 Ford F250). It got a little worse than there was a scraping noise than boom and the tread flies out from the right of the truck. I pulled off onto the shoulder and got out and could hardly believe what I saw. Luckily no one was to my right as the truck swerved to the right. The tire was almost gone, the rim was damaged the right fender and door damaged and all the plastic parts were gone. This was on a Saturday evening and I pulled the truck into a business so it was the truck was off the road. The next day we found some of the plastic pieces about 75 feet from where the tire blew. We took pictures and had to wait till Monday to find out what need to happen. Monday morning I contacted the wholesaler and he gave me the number to cooper tire. I called and they took down information and said I would receive a letter explaining what I needed to do to file a claim. That afternoon I was traveling home with my son and just before we turn on our road I start feeling another vibration and as I slow to turn the left front tire lets go and luckily the East bound traffic noticed and moved to the right because the truck swerved to the left. If the tractor trailer driver did not notice something was wrong my son and I would have gone head on into the tractor trailer. This time there was little damage to the truck and we were both alive praise the lord. Now I was on the phone a second time to cooper tire and turning in a second claim. This is Monday afternoon August 25, 2008. We got the truck off the road and I removed all the remaining tires and replaced them. Remember these two tires separated about 48 hours apart. I just got a letter from coopers insurance company and they claim I caused the tires to separate so they are not repsonsible.

I had a flat tire on my 2004 Ford F250. I took the lug bolts off but the tire would not come off of the axle. I called the dealer and they told me to get under the truck and hit the tire with a sledgehammer. This has to be very dangerous, particularly since the truck was raised up on a jack. According to the Ford dealer this is a very common problem with Ford trucks. I believe that this is a very hazardous situation and should be corrected.
