I bought a set of Mahle with tyres.
I brought them to a shop to have them balanced. When I put them on the car it started to vibrate at 90 to 120 kmh (55 to 75 Mph) Brought it back to the shop, redid the balance, didn't help. They say, the tyres may be warped. I bought them a new set of tyres, let it balance ... didn't help. They sent me to another shop that has a better machine. They put (a lot of)weigths inside and outside the rim (ugly), but it didn't helped. The problem occured when I bought these rims I figure they may be bent ... Could this old and wise guy be right ? http://www.youtube.com/watch?v=PeclYZQCyso Any advices ... |

I have original bbs wheels on my fiero and everytime I get new tires they tell me the wheel is bent and they are, two of them with no apparent damage. It still rides great up to it's max speed of 120mph. Their only bent about .100 and it's two wheels and I rotate them and have yet to notice any problems. The shops notice it when they are balancing the wheels. If the wheel and tire can be balanced on the machine, it's the rotor and hub assy. In the late 70's I had toyota gt's with aluminum wheels and everytime I would replace the factory tires the shops could never get the balance as good as the factory balance. You might need a better tire shop. Two sets of tires is a little suspect.
