Need Help

[xpnsvxj]

Ok guys and girls here the story. I got my winter setup about three day ago and put it on. I got the wheels and tires separate so I had them mounted and balanced at a local shop where I bought the tires. The first night was fine but then I started to feel a vibration in the steering wheel. It felt like the tires might not be balanced so I took it to a friend and had him check for me. Well just as I thought they where out of balance. So we balanced them and I thought I had fixed the problem. Well the something happen again the first night was fine but now the vibration is back. Does anyone know what could be causing this?(dunno)

Tires are 215/50/R17

Knowing the wheels would help.

What's the center bore? Your wheels may not be hubcentric.

Got hubcentric rings with the wheels and they are installed. Thanks for all your help so far I really appreciated it.

 

[Kain]

Does the vibration occur at a specific speed or is it constant? Also, does it happen when going straight and/or turning?

 

[xpnsvxj]

Happens between 70-80mph and only happens when I'm driving straight.

Are you using stock lugnuts?

 

[Kain]

Happens between 70-80mph and only happens when I'm driving straight.

How sure are you that you got the right hubcentric rings? What I'd do is get the car off the ground, remove the wheels, then torque them down to spec and in a star pattern. That will center them on the hub, rings or no rings.

Using aftermarket lugs that came with the wheels. I'll put it on a lift today and check the rings.

Thank Josh

were all the tires out of balance or just a certain one?

Ok so I just took my car off the lift and found that two of the hub centric rings have a little bit of play in them. I'm not sure if this is the problem because it is just a little bit of play in them. So I push them in the make sure they had a good seat and put the wheels back on. I bolted them in the star pattern to make sure the wheel was centered. I haven't had a chance to drive it yet but I will let everyone no how it goes tonight.

All where off a little

All where off a little

being off a little will not make them vibrate.

Most wheel balancers only balance a wheel up to 60mph depending on how old and what kind of balancer it is.

There shouldn't be any play with hubcentric rings. The fitment should be tighter than a virgin's honeypot. In fact, you may even need to use a rubber mallet at times to get the wheels off the hubs.

It's also possible that one of your brand new tires is out-of-round. Have they been "road force" balanced, or balanced conventionally?

 

[xpnsvxj]

What is road force balanced???

 

[Nliiitend1]

What is road force balanced???

It's a particular type of wheel/tire balancing that rolls the assembly across a roller/drum that measures the forces that the tire exerts on the roller.

This will point out any irregularities in the "roundness" of the assembled wheel/tire assembly. If it exceeds the predefined tolerances, it notifies the technician of the high and low spots so that the tire can be rotated relative to the wheel to get the most "round" shape possible.

It can make a pretty big difference over a static balance, especially when using large diameter wheels coupled with low-profile tires.

Ok so it is a lot better but still has a vibration at 80mph so I think I'm going to have to take it and have a road force balanced done. I really hope this will fix the problem all together. Once again thanks everyone for your help.
