Check "roundness" of a wheel at home

[LennyM1984]

Long story short, I have a wheel from my race car that took a hit from a spinning Ferrari. The tyre is obviously scrap but with the exception of a slightly deformed outer edge, the rim itself looks okay (and the tyre still holds air etc).

Is there an easy way for me to determine whether it is indeed still round? I've taken measurements and visually it looks solid (no obvious kinks or bends), I'm just wondering if there is any other way to check?

My first thought was put it on a car (if it isn't already), jack that corner up and spin the wheel.....you'll see if there's a dent/buckle.

Put it on the car.

When the car is still in the air set up something the exact height of the rim from the ground and then jack the car up slightly higher to create a very small gap between the rim and your stationary object.
Turn the wheel and if the gap between the rim and your stationary object remains constant then it’s round.

Brilliant. Don't know why I hadn't thought of that!

OR,
Take the wheel to your local tyre shop and ask then to put in on their tyre balancer. That will spin the wheel, slowly, when any distortion will be obvious. They can check the wheel balance too at the same time, not wheel plus tyre!

That would be the easy solution except all of the local, friendly tyre places have closed down near me. In the space of a year 3 have gone. It's a real shame as I used to use them quite regularly for normal tyres and fitting my race tyres. The only place left now likes to charge £25 a wheel for tyre fitting!

What is the wheel made out of, and how much would it cost to repair or replace?

With the cost of testing, entry fees, tyres etc, you do not want to risk entering any further race weekends with a wheel which may be about to crack
