Default wheel bent or out of balance

How do you detect if a wheel is bent or out of balance? Or if it is the tire that is messed up.

I have a wheel that hit the curb side ways . . . The tire popped off the bead and now it's put back. Driving under 50 MPH is ok . . . but when going over 50, the steering wheels jerks periodically. I have narrowed down to the wheel and tire, because while the wheel and tire was in the shop, I had another wheel and tire on the car and the car was smooth even up to 80 MPH.

Chieh

Jack up the front or rear and spin the rim. You should be able to detect runout if there is a decent amount by putting your finger on it.

Use jack stands.

Thanks. But I'm not sure what is "runout". Do you mind explaining that to me?

Take it to someone with a tire balancing mechine. That way any runout can be measured against what is acceptable. 1/16 inch I think for rims and 1/8 inch for out of round tires. Could be something like the tire bead is broken or not set where it's suppose to be. All this is difficult to determine on jack stands unless it really bent bad.

Bent wheels generally vibrate. If they are slightly bent, they might be able to balance them. If they cannot be balanced, they must be repaired or replaced.

The bottom line is, if you experience vibration that is probably from the wheels, have the wheels balanced and the usual suspects (alignment, etc.) checked out as well.

You could find a local tire installed that has the Hunter GSP9700 wheel balancing machine. One of the things that the machine does is measure wheel runout. Go to www.GSP9700.com to locate a local place. (Keep in mind, though, that some of the entities in the listing are in private hands, like engineering companies.)

Thanks. I tried looking for a GSP9700 this weekend. Found a place online as you recommended. It took me 30 minutes to find it, because it moved and no longer had a GSP9700 . . . Anyway, they balanced the tire and wheel again. It wobbles . . .

So if it is a bent wheel, is it possible to get it fixed? Is there any place that fixes wheels? Is it worth it? Or should I just chuck it?

Just ask your local "tuner" shop; they ought to know who repairs wheels locally. As for is it worth it, that all depends on how much the wheel costs. Low-mileage WRX take-offs sell for around $75 each, but fancier wheels or those in shorter supply will cost more. I was able to get a whole set of 4 WRX rims w/Dunlop snow tires mounted on them (and only a few k miles of wear) for $300 total from a local guy on the forums who sold his WRX...
