I was working on some Champion chassis today, cleaning them up.
 
Both had the dreaded front tire rot.
 
I chucked the wheels in a Dremel and removed the offending crud using a single edge razor blade. Please be careful if you do this. A quick pass with a Scotchbrite pad finished them off. The tires are from older model kits. They seem to fit the bill although not original. You can chose different tires or sand these smooth or slightly resize them if you prefer. I have no idea where you could obtain originals as I doubt the tires were sold separately. I don't remember seeing the front wheels sold separate either. 
 
Just my solution to a common problem.

The original Champion fronts are a mix of synthetic rubber and the real thing and can rot if left under certain conditions. The best repair is to make a composite silicone mold around a 1/8" axle and cast a new black urethane tire over the cleaned wheel. A bit of a bitch but it then lasts forever.

Umm, casting tires in Urethane, sounds like an idea. Oh, wait, I bought this stuff years ago and never got "around to it" :dash2:

 

I wonder if its any good anymore. I guess theres only one way to find out.

Joe,
these products have a fairly short shelf life... test it first!

Silicone will cure around the old tires. It can be used to make a mold of the old tires. Urethane can then be poured into the silicone mold and it will cure and make a nice original size tire.

This process cannot be reversed using urethane as the mold and silicone as the the tire compound. Silicone will not cure when in contact with urethane.

Well, as Dokk suspected, the stuff was junk. It was harder than learning Cantonese. I guess I should have gotten to it 8 years ago  :dash2: Stupid waste of money on my part. I hate when that happens.

 

Allen, I have not seen these sold separately although that means very little. If Scott does not have them, then they may not exist.

 

Maybe Dokk can verify.
