Rode in 2 buddies yesterday on same road at same speeds and we realized something is wrong. Took it to the dealership today and they are checking to make sure the wheels around tired are in good "round" condition. After we determine it is not the rims out of round or a bad spot in a tire I will look at replacing the shocks. The "pro suspension guy" that drove my truck said the vibration and jumping is not in the steering wheel it is in the body which usually means it is coming from the rear wheels. My stock tires called for 65 punds of max pressure and they were all the way full so they were backing them down to aroud 50lbs for starters. I still beleive I need all new shocks but the dealer thinks we have another problem besides that. Will let you know the verdict today. Anyone remember whast it cost for their michellin on 20's? I figure I would be out about $1200 or so.

A broken belt in the tire carcass can make it squirrley, but that is more side to side than up and down.......

Umm i had a broken belt and my truck went up and down....Same with a little company car that broke a belt in the tire. Usually you can see a broken belt though (big lump in tire).

Are there different types of tire balancers? What is the best? The vibration is constant and I beleive is caused by this

I put some Michelin ATX/2 on my truck last year. Made it very quiet and smooth. Michelins will not need a lot to balance and will pretty much stay balanced and last a lot of miles with regular rotation. I had a relative that worked in the tire industry and from what he told me, I always buy Mich. Mine is a 06 250 King Ranch. It has 18's on it. I don't know if the tire is made in the 20 size. Next time you roll through BG come take a ride in mine. Eric

If you balance the tires make sure you load force balance them.

Ok...Had the tires balanced yesterday. Took the truck out and didn't fix anything. Once again the vibration is not from hitting bumps etc, the vibration is constant and felt in the seats and not the steering wheel. They are checking the ball joints/u joints etc today to see if they show excessive wear. I am not sure what load force balanceing is but if it has to do with towing the truck does it when it is on empty load also.

Don't go by the pressure called out on the tire ... you go by the pressure called out fo r the vehicle ... usually on a sticker in the door jam .

Fo over to www.ford-trucks.com Do some searches first then post if you don't find a similar issue. You'll get much better results there than wasting your time on a boat forum. My guess is that someone there has had the same or similar issue and already has a fix for it.
