Soft plastic cure?

[Shark]

I am doing rebuild where unpainted wheel became soft around the outside rim from being in contact with the tires. Anything I can do to reverse this and save the wheels. Thanks

Nope, sorry to say, they're toast.

Steve's right. They're history.

BUT...depending on exactly what you need, you can machine the soft rims off and save the centers.

The chrome wheels on the left (below), from an AMT Cobra, had softened rims, but the centers were fine.

I machined the rims off to use the centers with rims machined from the red wheels.

Steve, thanks, I was afraid of that but hopeful.

Bill, that is a great idea, the wheels I am doing look like the ones you did.

If you have a mini lathe, you can make real metal hoops out of aluminum tubing.
