I have a 2005 Lariat with 18 inch tires with 8000 miles so it was time for rotate and balance. I took it to the local shop (friend of mine) and had everything done. First time I got out on the highway after the rotate and balance I noticed a vibration that I had never had before. Took it back to the shop and they checked all the tires and then had me look at the left front time while on the balancer. It took more weight then all the other tires and also had some wobble while on the machine. Proceed to take it back to the dealership. They road forced all the tires and said everything fixed. Now the problem, the truck rides great, maybe even better than before, but the tires seem much louder than before (sounds like a whine).

Anyone have any idea or experienced the same issue? Could I have a bad tire?

Thanks!
