Bunk on tires slipping on the rims unless a top fuel dragster.

 

He is right they are not spinning on the wheel, you should look on the web for road force balancing there is a couple of websites that have animated explanation on how road force balancing works. the bottom line is you need to find a good tire shop that has a road force balancer and will take the time to balance your tires the right way. If you have a tire or two that are out of limit for road force balancing the tire shop should get you new tires. that is how it worked for me. i had a 04 quad 1/2ton 2wd with 20's and i got 80k on my first set of goodyears that came with the truck, then i tried a different brand and they shook like mad, went back to the tire shop. They said that the new brand i bought was not that great and let me return them and get goodyears. One of the new godyears was not within balance spec so the ordered another goodyear and did it everything was great after that. So just make sure they are decent guy's and are willing to go the xtra mile to make the customer happy and you should get it figured out.
