maybe 10+ years ago I remember it was the "cool" thing to do and people would run foams tires on indoor clay tracks.

anyone remember doing this?

I was trying to find any specs on what tires were used, but coming up blank

About 20 years ago, I used to run my Kyosho Optima 4wd on a dirt oval track in Costa Mesa, CA. I and everyone else used to run foam tires there. We then sliced various crosshatch patterns into the tire surface for more grip.

We used to run foams on High Traction Dirt Oval tracks but I have never seen it in off-road.

Proline/Jaco made tires just for dirt, They had silver, gold compounds and a few others.

They were very hooked up!!!

As others have mentioned while plenty of people did, and still do, run foams on dirt ovals - but I've never heard of anyone running them offroad on dirt with any success especially considering how hard they are compared to foam insert rubber tires and the fact that rubber compounds have progressed so far in the last 20 years.

our local track is having some funky times with traction and wanted to try some different things.

I was thinking back to how well the foams used to work and wanted to try them and see if they still do.

Since there are so many variants of foams, there should be one that can come close or beat the performance of rubber tires for your application.

Go to www.mcmaster.com and search "foam", it will help you in seeing all the variations:

Durometer
Tensile Strength
Temperature Range
Density
Stretch Limit
Foam Structure
Compression Recovery
and many more...

With Paragon traction compound?

We used to do the same all the way up through running Custom Works dominators / intimidators. Only in western PA we'd use window silicone to 'coat' the tire, it would make it very tacky.. like an early rubber slick tire.

i used to run silicone coated foams on my enforcer sprint car running on a clay dirt oval i also ran "caps", foam tires covered with a skin of rubber that got tacky when they heated up

Funny that yall are saying this. I just saw an ad for some Jaco Prism foams for the Traxxas Rustler and was wondering why in the hell they made special foams for that truck? Guess I know now.

they make those for the guys that are running a 3cell lipo in their VXL systems and are blowing rubber tires off the rims

i was a roar nats race and saw brian kinwald run foams in his last qual. back then the tracks were really dry and blue grooved like a dirt oval track might have been green or yellow compounds and were grooved for improved traction
