I have a set of 3 piece wheels that are rather old, but straight, and very light.

But they leak like a fish net.

So, I will pop them apart, and clean and reseal them. Any hints?

What should the sealant be? I called Tire Rack and they suggested silicone. I agree that it might be a good choice, as it remains somewhat flexible. I'd think getting the highest temp stuff availble would be key.

Thoughts?
