Tire shake
I have only had the truck on the road for a few days and I am not to familiar with driving a truck with such large tires. I have a 77 F250 4x4 with 35 inch grounghawgs on it. The ride is quite bouncy but that is expected, What has me concerned is the tire shake. I think I need an alignment, could that cause it to shake? It kind of feels like a tire is loose or badly out of balance, but even at low speeds its bad. Could this just be due to the knobby tires? Or a misaligned tire? The one tire does look to be off a bit, the truck was never aligned when I put the larger tires on, it orginally had 33 inch tires when I bought it but never drove it with the smaller tires. The new 35 inch tires were already balanced when I got them.

If the tires are cupping, you'll need to do an alignment. It also could be that you have some worn suspension parts like ball joints or kingpins, tie rods, drag link, etc. Usually, out of balance tires will be noticably only at certain speeds.

the tires were cupping when I bought them, the guy I got them off of had them on an newer FORD with Independant Front Suspension so he said thats why they started cupping. The tires that were on the truck orginally were fine, normal wear.

Take the the truck into a shop that you trust and have them look at the front end just to be on the safe side
Whether something is wrong with the front end or not, I would ballance them and put the cupped tires on the rear. Aggressive tires will tend to cup if left on the front to long (especially on a Ford). Therefore, make sure to watch them close and rotate them on a regular basis. You might find just rotating them and wearing the cupped tires smooth will take care of it.
Good luck

HI,
The way you described the problem looks like pretty much the same problem that I had with my truck. When I was driving it felt like i was gonna loose a wheel but the wheel was torque at 110 pounds so I've finally found that the problem was my wheels bearing that were loose.
I've replaced the lower and uper bearing for each front wheels and the problem was solved.
If you want to check if your bearings are loose. Just Jack the front of the truck and try to shake the wheels up and down or side to side to see if wou have a loose in them. they should be very tight. if there are loose. that means you may have to change your wheel bearings.
Also it could be possible that the ball joints would be bad as well.
but in my case it was the wheel bearing. remember larger wheels and tires are hard on the wheel bearings so check them out.
see ya, hope it helps
let me know how it turned out.

I'll check the bearings as well, right now the truck is in for a safety, they didn't mention anything about bad bearings so hopefully they checked. I do have to replace my rear axle seals and brakes as the seals leaked ontot he brakes pretty bad. I guess my u-joints are fine cause they did not mention anything about them either. I should get the truck back tomorrow to check the other things myself.
