Rim problem?????????

hellrot_M3 · 03-20-2009, 06:22 PM

okay so i installed my new rims and tires. I put on 18x8 rims all around with a 41 offset. Tires are falken 912's. The bore size was 74.1 but hubcentric rings were put on to to bring it to 72.6. The problem is that i get a ridiculous vibration between 90kn-125km. the wheels were balanced and they fine.

what could this be?

thanks

metal hubcentric rings or plastic?

hellrot_M3 · 03-20-2009, 06:43 PM

these are metal hubcentric rings

have you checked to make sure all the bolts are tight enough? sounds stupid but i had this exact same problem when i first got my old e36 from the dealer turned out that the idiots just had not tighted the bolts enough

And you're 100% sure they are 72.6?

hellrot_M3 · 03-20-2009, 07:01 PM

well im not 100 percent sure but when the rings were put on the hub, they fit perfectly into the grove. and yes all the bolts are tight and torqued

can this be some thing like an alignment?

I'd double check you got the right size rings first, should be stamped on them

hellrot_M3 · 03-20-2009, 07:15 PM

would another ring fit thats not fit for my car? may be a dumb question.........

Jack the car up, spin the wheel. I had the same problem after I had new used tires put on, 1 of my rims was bent.

hellrot_M3 · 03-20-2009, 07:22 PM

but the tires and rims are both new, not used but all new in boxes.

That don't matter. I had brand new tires and rims and my 540i shook like a MF at 100 to 120kmh. Replaced all rims same problem. It was the make of the tire for my car that represented the problem.

tires might be defective - especially falkens

x3 there might be a cord broken and you wont see it when you spin the wheel, were did you get them put on? what kind of balancer do they have. at my shop we have a top of the line balancer which can detect broken cords or any defects in the tire or rim.

also when they put on the wheel they might have crushed the ring, or wrong sized ring.

edit- didnt see the last post, like i said tires. Go with the toyo's there a really nice tire

^^^ I was going to say tires. or balanced improperly.
