Whats causing my vibration ??? Front of truck

make sure the bead of the tire is out all the way

 

Hmmmmmmm. What is the frequency of the vibration? Example, 500 times a minute vs 1600 times a minute? Difference between the "rolling" parts vs the drive shaft. The wheels, especially aluminum, have to have the bead seats cleaned & lubed when changing tires, other wise, the "G" ring, that little raised rib that is just outside of the wheel diameter will not be concentric with the wheel, instant vibration. Also, the "dot" on the tire has to be alighed with the valve stem!!! A LOT of folks will argue with this but...... why would the tire mfg's go th ALL the trouble on the "line" to put that "dot" on if it didn't make a difference? If the bead seats are not fully out against the rim of the wheel that will cause a vibration, if the tire shop didn't clean the interior of the wheel prior to balancing, ie grease, dirt, etc. on the wheel, the balance is usless. There are a LOT of things to consider when changing tires & chasing vibrations

 

cracked a leaf on my carhauler and it shaked bad.
if i went fasted it smoothed out for a bit then got worse

 

LOL I had a "tire shop" argue with me on the lil dot. Said it was just a mark after they made the tire and I told them its a mark for a reason...just put it where the valve stem is and make me happy.

 

GREAT answer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Keep the greasy side DOWN !!!!!

 

I changed my mind,.. again,... This guy.. "Has my Vote"
