Vibration around 55mph
 
My 58 Tbird has wire wheels, with Coker tires and tubes. Around 55mph it starts ti vibrate or shimmy. I had a similar problem with my 65 Mustang with unilug wheels. I bought new wheels and the issue went away. I like the wires wheels. I have only had the car about 4 years, Went through the front end, new ball joints, etc. My mechanic seems to have a hard time getting these wheels balance. I really do not want to buy new wire wheels, so is there someone that can work on these wheels and true them up?

Wire wheels can be a challenge at times.

Do the normal vibration diagnostic steps.

- look for marks indicating a missing balance weight

- spin the wheels manually and see if it runs out or is bent. Use a dial indicator if you have one & measure/record run out.

-Put front wheels on back, back on front, or borrow all 4 from another car. If vibration changes or is eliminated you indeed do have a wheel problem.

- were your wheels balanced by a stud centric or center centric method? Proper way is stud centric.

Yes they can be "trued" just like a motorcycle/bicycle wheel, but finding someone to do it will be difficult.

Just re-read your post and saw:

Tell him the recommended procedure for these wire wheels is to be stud centric balanced ESPECIALLY if the large center hole of the wheel is larger than the OD of the hub on your car. If he is balancing the wire wheels using the center hole, he will indeed have trouble.

You can get beads or BB's to put in the tire, and it
will self balance all the time. Does not always work,
but many have been happy with using that method.

Are you running radial tires?

There is some evidence that radial tires load the rims a lot more than the old bias ply tires did. If these are old wire wheels and you are running radials that might be an issue?

Just a guess.

Let us know what you are running.

First thing I would do is, rotate the wheels (frt to back) and see if the vibes change. Could just be a bad tire.

Take the whees to a (good) tire shop
and get their Ace to balance em for ya.

Try another set of tires/wheels.

If you have eliminated that issue, I'd move on to u-joints, motor mounts (trans mount) etc.

I had wires on mine for a few years. NEVER AGAIN!! Unless I had a car that I was just going to back off a trailer and park at a show. That ship sailed for my car the day it came off the assm line.

Wire wheels look kinda cool - But too many problems. And tubes . . . . No thanks.

Good luck

John good advice but I still like the Kelsey Hayes my wife has in her 58:)
Just noticed something on your bio. Looks like your Dad bought the 60 convert the year you were born ?

Unless a wheel is bent, or has lost a weight, or the a tire is faulty, the problem could be elsewhere. It could be ball joints, universal joints, tail-shaft. But wait a minute, you said the ball joints, & universal etc., were done, therefore it has to be one of the first 3.
At a guess I would have to go with a faulty tire. But then again you say that the mechanic has a hard time balancing the wheels, not wheel. Try a different wheel balancing place, just in case there's a problem with his balancing machine.

Thanks for all the suggestions. i am running Coker radials. I have rotated the tires front to back and side to side. I have had these tires balanced 4 times in the last 3 years. His balancing machine is the standard center hole. I have heard of tires being balanced on the car. maybe i will see if someone does that in our area. I have used the balancing beads in the wire wheels on my 1926 Model T speedster. They did help on that car. But tires are much smaller and car is about 1/4 the weight. I guess the next thing I do is take my new rims off my Mustang and try them on the Tbird. We really like the looks of the wire wheels.
