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 ... |

Are the front wheel bearings properly adjusted so there is no slop?

Anyone here use balancing beads?? I used these on my wife's minivan and they work incredibly well and the tires are wearing VERY evenly (well as evenly as they can with Ms. Andretti at the wheel). The 914 will get them when I up-grade the tires. |

I know a guy who used high density air-soft BBs with equally good results. He just used 3 oz in each wheel (popped the bead on one side and poured them in). He was out the door with perfectly balanced tires for about $7 from WalMart. . . Your tires sweat on the inside as they get cold and hot, so steel BBs will tend to rust and go away over time. 'Course it would likely take a long time and you'd likely need new tires before that happens. I do balancing on my restoration cars with these since it's cheap and allows you to not have to run ugly weights on restored wheels that can come off and ruin the finish. |
