Ever since I got the rims mounted on my Vigor, around 70mph-80mph it will shake like a bastard sometimes. It comes and goes, but is there more often than not. Sometimes it will go away at higher speeds, other times it will get worse.

I performed a 4-wheel alignment and had the wheels rebalanced and it still happens.

I've heard two suggestions: Wheel spacers and center rings.

Can someone enlighten me as to what the problem might be and how to fix it?

 

Nobody knows? :down:

 

Sometimes they won't notice a bent rim unless they're looking for it??

Wheel spacers just change your track. I don't think they'll do any good for your vibration. Centering rings just help hold the wheel centered. The center hole is supposed to fit close around the raised part in the middle of the hub. When the lug nuts are tightened properly, I don't think that's your problem either.

Find a place with a Hunter GSP9700 (URL below), that can measure road-force variations while it's balancing your tires. Maybe the tire itself isn't quite right??

The rims and tires are brand spankin new but I'll see what I can do

 

OK I didn't realize they were really NEW. So ignore the bit about a bent rim...

But a tire with a carcass that's not quite round or straight, can be balanced perfectly when it's spinning in the air. Then when you put the weight of the car on it, it squirms around & feels like it's out of balance. That balancing machine does it's work while the tire is pressed against a roller. So if a tire is defective, that'll give you some credibility when you go make a warranty claim for the tire.

 

Yeah check your tires. I had a bubble in one of mine and I had the same issues.
