Default Where to get foam for large tires?

Hi guys,

I have some questions about foam tires, and I'd really appreciate any help:

1. What type of foam material is used for r/c tires and where can I buy it? (like in sheets, rods, or tubes)
2. Where can I get large diameter wheels and foam tires, like 3-4" diameter? Are there any premounted foam tires in that size?
3. How do I mount foam tires?

Thanks!

I'm not as up on it as I used to be but the basics are that the different foam compounds are alloys (mixtures) of various plastic (synthetic) and rubber (natural) chemical compounds that are then made into foam.

I used to (early 90's) get foam from a die cutter that bought the foam from a factory in sourhern Virginia that is no longer in operation. I don't think any of it is no make in the U.S. for environmental reasons.

Maybe one of the smaller tire companies like BSR could do it for you on a custom basis - donuts can be cut by water jet machines that are fairly easy to program.

Can you remember the specific name of the foam? Urethane, neoprene, silicone, vinyl, closed-cell, open-cell?? As for cutting the tire, I think I can manage that myself. My main interest is getting the right material.
