Wheel problem...LOST...

[Comm MD]

Heres the deal. I purchased some aftermarket rims as you can see. When I put them on and drove on them, I have a nice vibration going over 40 mph. Going off that and purchasing these rims balanced, I ordered some hubcentric rings. Putting those on yesterday had no effect whatsoever. Now heres a kicker, sometimes(like once every 2 days) the vibration goes away for like 15 seconds and then comes back(extremely wierd). Before I had these rims, I had no vibration whatsoever, even goin 115MPH so I'm rulling out any steering/suspension probelms. So I'm stuck between a rock and a hard place. Do you think they were balanced wrong? Or has anyone else had this problem before. I looked on each rim and there are weights on all of them(in case they missed one). All the tires look normal too. I NEED HELP! Any suggestions??????

Are the wheels torqued properly ??? 85 ft-lbs i think is what our wheels should be at. Please correct me if i'm worng.

Yup

How long did you drive without the hubcentric rings? It's possible that the vibration warped the wheel a bit if you drove too long.

But, first off, I'd get them balanced again. I don't trust when you buy them pre-balanced. I've done that twice, and both times they weren't balanced worth a damn. It shouldn't cost you more than about $40.

Yeah I figured thats probably the reason, at least I hope it is. I'll get them rebalanced on Sunday. But if there is any more suggestions let me know.

Balancing is the likely culprit, but sometimes tires can slip a little on chrome plated wheels. It's possible the tires were balanced correctly and then after you drove on them a bit, the tires have moved from their original mounting position (due to acceleration and braking torque forces).

Take them to a tire shop and have them check each one first before rebalancing.

i had a very similar problem with my last car , i never got to figure out what it was , i just ended up blaming it on the rims since i got them pretty cheap , it was wierd one day it would be fine next it would shake alot , upto 40mph no problem , over that started shaking until i reached about 60 mph, i just got used to it hope this is not the case for you

Leftyrev , i had the same issue as yours , one of my precious cars was a 2000 corolla , put on it some 16" , the thing is , they did the same , vibrate from like 90 or 100 km , till 120 or 130 km , i balanced them like 5 times in diff. shops! got the centric rings , did everything , went from 215/40/16 to 205/45/16 , and still that vibration , then i just couldn;t find any other thing to blame but the rims themselves , since i got them really cheap , and realized they were an exact copy of the Konig Flight. so guess the rims were so bad quality , nothing could be done!
i just say , don;t get any wheels , get some branded recognized ones , that;s all , with the right specifications , and u should be alright!!

Well come to find out, you were right. The balancing was way off(like 3.5oz) on each tire. Total idiots dont know what there doing. So A note for everyone. Double check or visually watch your wheels getting balanced. Also ensure they do both types of balancing(static and dynamic). I guess the first place only did static balancing. Hope this helps others if you had the same problem.
