Whats your opinion?

I just had my dealership put on a set of Bridgestone Dueler AT Revos 285/75/16. They also adjusted the speedometer for me. In addition I believe they may have cranked the torsion bars a little as the truck seem to be sitting very level.

 

Now my truck starts vibrating at certain speeds (usually aroung 50-60). Which is the most likely culprit:

 

1. The new tires, out of round or not balanced properly.

2. Cranking the torsion bars( I know that if they did crank them, they did not do an alignment).

3. Adjusting the computer to read correctly.

 

Truck is a 2003 2500HD ECSB 6.0 4x4.

 

P.S. The truck looks great with the new tire setup. If I can figure out how to post pics I will. I noticed a lot of you run 265 Revos, anyone else out there running 285 Revos?

If they cranked the T-bars they better have checked the alignment.

 

Vibrations at those speeds is usually caused by an out of balance tire. Get them rechecked. Possible that one isn't truly round either, had that happen once on my car.

Tire balance.

Had this before on previous truck. One tire was out of round, and the alignment was off. Take your pic. I would take it back to the dealer and make them fix it before it ruins your new tires.

Definately take it back to the dealer. You paid fo rthe truck to be done right so make them do it right.
