so i put 73mm center bore wheels on. original bore is 67mm. the new wheels use cone seat tuner lugs so i assumed the wheels were lug centric. while driving at and over 60mph, the car vibrates like my girlfriend's favorite toy. has anyone else experienced issues with hub centric wheels? i put hub centric rings on today but havent driven above 60mph yet. gas is expensive and the freeway is far from me. :D ive read that by not having the hub centric rings, vibration is a symptom and the bolts can actually bend and possibly break off. more info please. thanks.

You've just described why it's necessary to have hub centering rings. One error in your post, though. Your wheels are lug-centric, not hub-centric. Hub-centric wheels don't need hub centering rings (ie the stock wheels are hub centric, center bore matches hub size exactly).

thanks, but i got that part. the stock speed6 wheels use cone seat lugs also, but the center bore fit perfectly over the hub. now that i have new wheels with a larger bore and no hub centric rings, ive been experiencing vibration. i was wondering if the vibration was a symptom of lug centering when the center bore is larger than the hub? i got the rings on and ill test it out today. otherwise, maybe the tire installers didnt balance them correctly, but i watched them while they did it and it looked alright.

That should be the problem. Whenever I sell wheels on a vehicle, I MUST make every attempt to make the fitment as close to stock as possible to avoid any problems. I have NEVER heard(in 12yrs) that the studs will bend from a lug-centric app. lol *over-analysis* Every once and while I don't have the proper rings. We just torque the wheels in the air to try and get the most centered fit. If you still get vibes...have them rebalanced. - Chip

i think i have them around 80. best way to find out is to break loose the lugs with a torque wrench.

87lbs - Plus if you don't tighten them equally at the same time, you will get the vibration as well...

I'm not even running hub rings and my don't vibe at all... I just torqued them to 35lbs then 60lbs and then 87lbs... In the standard tightening bolt pattern...

did you use the same spec (35lbs, 60 & 87) on your ADR wheels?

Yes that is what I was referring too...

Also a side note, depending on the tire you have, you might "feel" the road even more because of a lower profile tire. It shouldn't vibrate, but it prob will feel a little different then stock.
