Just put on 4 new Michelin LTX MS/2 (265/70/17). I now have a shake that varies a little at different speeds. At 40mph it is very noticeable and even at higher speeds I can still feel it. They have re-balanced the tires once but the problem still exists. I've changed the steering stabilizer but no help.

Could the tires be oblong causing the vibration?

What other front-end components would cause me to feel a vibration with new tires?

I have spending $1000 on tires and then feeling this vibration.

Thanks.

 

It is possible that the tire is out of round. But, my experience shows Michelins are very good in quality.

If it is out of round, I ussually have someone drive it while I follow to watch each tire.

When they rebalanced them, did they remove all weights first? Any chance they got something inside the tire during mounting? This is easy to check by running the balance a second time.

 

You may be experiencing "death wobble". From what I have read, it is common when changing tires on 3rd gen trucks. There is a steering box stabilizer you can buy that is supposed to fix it. It's a bolt-on solution.

It isn't death wobble. If you do get death wobble you will know it because you will fear for your life and regaining control of your truck will be so scary you will not forget it. I've had it and you don't want it.

You probably have a bad tire. It happens. It could be a bad belt or an out of round tire. If the installer has a force balancer he should use that to determine which tire is bad.

 

I would also lean towards a tire issue. Death wobble happens, but you will know that when you feel it, and the fact that the only thing which has changed before and after are the tires, leads you to the conclusion that the tires are the culprit.

 

had very same problem when my new tires were installed. Soon as I hit the hiway, 40-60 mph wierd shimmy. Re balanced 3 times, turns out right rear tire was never seated on the bead all the way. Very annoying after 1000 bucks and 4 days of taking it in.

 

Two ways to check the source of the problem. You could move both rear tires to the front and vice verso and see if the problem changes. The other way is to one by one, run your spare and see if one wheel eliminates the problem.
Either way, if something changes, you will have a clue where to look.
