My dealer gave me a bunch of shit today about having to test ride the truck and it won't be looked at till Thursday or later because of my vibration... And get this, they said mine was the first to come in for this reason... yea...
I ended up going straight to Goodyear and they force balanced the tires and found one wasn't able to be balanced at all. Plus 3 out of the 4 were WAY off. Tire will be in tomorrow and replaced under warranty without going through the dealers crap. The tire machine said the tire was balanced, but then they ran it they told me to watch because it was so bad. The machine was literally shaking laterally side to side and the machine said the tire was good at the same time... Even with the 1 tire still terrible, my vibration is almost gone, and tolerable how it is. In and out in 30 minutes and I hope this solves my problem.
Take your trucks to Goodyear direct and you will be taken care of immediately and then you can almost rule out the tires if your still having problems.
My vibration was between 72-85 mph
