i just got these wheels about a month ago and had them mounted and balanced. as soon as i put them on my car it developed a pretty bad vibration between 80-85 mph and 110-115 mph. is it possible that the wheels are bent? they are brand new from tire rack.

should i go back and have them rebalance them?

 

rebalance first

 

may have to get the tire spun on the wheel then remounted properly

 

its probably a balance issue, thats what it sounds like

 

thats what i am thinking too. wanted some other opinions

 

it would be really un likely that the rim be bent, being brand new. go have the re-balanced at Discount Tire see what happens

 

hub centric rings?

 

they came with the rings. i got them from tire rack. they include the rings, and lug nuts.

 

Rebalance

 

get what is called a road force balance. you wheel may be in balance but your tire may not ber perfectly round. ive seen it alot where the tire itself is out of spec and sometimes a rotation of the tire on the rim can help. but sometimes you just have to get the tire returned to the manufactirer and get a new one.

 

that might be hard to find/do in germany.

how tight should the wheel be on the hub with the centric ring installed? as in when you put the wheel on the ring/hub with no lug nuts installed should it stay in place pretty well?

 

Auto skills center guys are probably not the best at balancing tires. LOL Go get it done at another base.

 

yeah very true. i am going to call them tomorrow and see if they will rebalance for free. if not i will take them off base.

 

when the wheel is mounted properly it should not move at all. If it does, you've got a problem. The lug nuts should hold the wheel tightly to the hub.

 

i think you miss understood... i am talking about with no lug nuts installed... the lugs do hold them on tightly when installed. i am talking about when you first put the wheel on the studs and against the hub. should the centric ring be able to hold it tightly in place? or is it ok for it to still be a little loose?

 

oh ok, as long as you can't move it up and down, and it just tilts on the hub (like any wheel without lugs on would) it should be fine. If you've got the rings on and you can still get the wheel on, it should be fine. Make sure they fit tightly on the wheel, then take the rings on and place them on the hub, and see if they fit tightly. As long as it fits both places snugly, you've got the right size ring.

 

all these ******* tire shop guys drive me nuts.

all they do is run the balancer, throw weights in then over tq all the lugs with the gun


proper way to do it is run balancer, add weights, then run balancer to ensure it's zeroed out. ive had one wheel out of balance(weight came off) for a LONG time now...that tire is a lot more worn down than the rest now and gets pretty bad vibes around 70-80

 

Yeah I know what you mean. Sounds like what is going on with me

 

Don't rule out the tire itself, it could be that some of the belts in the tire have shifted throwing it out of whack.
