Continental 315/30-22 Balance PROBLEM

[williamssk123]

i just installed 22 inch replica 4.8 wheels on my 04 x5 3.0 sport package. They are 22x9.5 in the front and 22x11 in the rear. I am running 265/35/22 in the front and 315/30/22 in the rear. The wheels and tires look great but It rides horible. I have gotten the tires balanced 6 times in the last 3 weeks and had one rear tire replaced and still no help. It was also balanced on a hunter roadforce one of the times. I have had very bad rear vibration. The front just shakes from side to side. They are replacing the tires with toyo to see if it helps. Any Ideas on the problem? I am hoping the tires are not round. Everytime the have balanced the tires they have been out of balance by a little bit.

The only other thing I have done was to have the truck alinged before I put the rims on. I had the shop set it as staight as possible to avoid wear to rear tires. I road on the truck with the stock 18 inche wheels for 1 month before I put the wheels on and had no problem.

Anyone ever put these small balls in there tires. Dyna balance I think is the name. People that have tried them love them.
