Lol ya thats a funny thought. I know alot of people like offroad foam tires just not my cup of tea. I tried it years ago and didnt really care for it. Carpet tracks that run foam typically have issues running rubber tires. Seems the foam dust makes the track marble like for the rubber tires. Vacuuming can help but it doesn't get it all out. With black carpet I see no reason to run foam tires. Rubber tires will last longer than the foam inserts and foam tires are consumable. Foam tires are much harder on the drive trains plus you have to deal with a dirty car from all the foam dust getting EVERYWHERE.
