I installed my new TT2s and brand new Verdestien tires. Had a reputable shop spin balance them, and install them. Now I have a bad shimmy in the front end starting around 45 mph and continues to get worse the faster I go!
Anyone else experiance this with wheels or tires?

Those TT2s are sometimes "out of round" one of mine is slightly. Could be the problem.

True^^ or maybe it was a shitty balancing. I've actually had a shop mount and "balance" my wheels. When I saw them putting them back on my car I noticed that there were ZERO weights on them. I'm not an idiot so I had them take them back off and balance them. Wouldnt surprise me if they halfassed it though.

I would check in the barrel to see if the weights came off or are there at all. Everyone makes mistakes (the shop) so just double check.

Make sure the bead of the tire is seated properly on the wheel. Have some one mount the wheel and tire on a balancing machine and spin it. Observe if the tire appears to hop up or down while it spins. If there is a hop break down the bead and turn the tire on the wheel, say maybe 90 degrees, keep doing this untill there is no longer a hop. If that doesn't do the trick you may have an out of round wheel or tire. A shop with a run out guage should be able to determine if there is a problem. You may also want to find a shop with a road force balancing machine. If the wheel is non hubcentric it is also a good idea to gradually torque down the lugs with the wheel and tire off the ground.

Or more than likely the shop just doen't know how to balance a tire.
Even though it's a reputable shop, Igor the technician, (high school kid) may have been doing the work. A reputable shop doesn't mean everyone there knows what they are doing. I've taken cars to reputable shops that didn't know their *** from a hole in the ground.
