Hi guys. After switching to aftermarket wheels with new tires, I have noticed vibration in the steering wheel when driving on the freeway (there is no way that this steering wheel shaking is normal). I had the tires balanced with a hunter road force machine, but I still feel the vibration. What do you think is wrong? Thanks.

 

Sounds like you didn't remove the little ring clip that are on the studs. Thats my best guess as since everyone that switches to aftermarket wheels has this issue.

 

Remove these from whichever wheel studs may have them.

 

this either 4 things

as above the metal clip
the wheels have to be balanced with zero tollerance
SPIGOT RINGS are essential 100%
toe in maybe slightly out

for sure it's one of those..please fit spigot rings if u dont have them..the wheels will never sit on the hubs perfectly and is dangerous...

i hade this problem on all 3 of my mustangs..if all the 4 things are spot on i garantee the wheel wobble will be gone..dont forget low profil tyres flat spot very easily ..mine flat spot after a weeks sitting still..takes about 30 miles untill it's gone

 

Take it to a shop that knows what they're doing balancing.

I had luck going to a reputable shop in the "vibrant" area of town that deals with 26"+ stuff daily.

Anyone can get a road force balancer, but it takes someone that knows their **** and actually cares to get your tires balanced correctly. It's not as easy as "put the x weight here"

 

I couldn't agree more....but definitely check for those pesky clips that Nuke pointed out.

 

I definitely removed the clips. Anymore suggestions? Thanks for the input guys!

 

i told u the other 3 things it will be..
more than likely a balance issue...try a different store

 

I had a real bad shake last summer, found out my front tires were about 5 lbs low on air. Filled them to the right pressure and 75% of the shake was gone. Just a thought.

 

what Rudolph said. he's calling them "spigot rings," but here you'll probably find them as "hub centering" or "hub centric" rings. The wheels are supposed to be centered by the hub, not the lug nuts. The factory wheels are machined to fit the Mustang's hubs precisely; aftermarket wheels can't because they have to fit a wider range of cars. If you just throw the wheels on there and tighten the nuts, the wheel can be off-center which will cause a *bad* vibration.
