Grand Prix tires, Moody and other dirt oval tires.

[Charlie don't surf]

Thin rubber "cap" wrapped over a foam tire, I have some old ones here somewhere- we used them at tracks that didn't allow foams. Rubber over foam equals flubbers

AKA "caps".

nah, radial caps are asphalt belted rubber tires with closed cell cores. The dirt oval flubber is a mounted and trued rubber foam, trued to a desired size and shape then coated with contact cement or silicone then a thin soft rubber tire is placed over the foam tire. Kinda same principle ( very low expansion during high loads and wheel speeds ) but the caps were used to maintain traction on high speeds, the flubber was a way to get around the " no foams " rules at tracks when you came into town for a big race.

Here Is a really old and shot set

Yeah guys, post old oval stuff. Thanks for the flubber info. The Grand Prix are manufactured by Mrc. Well that's what is marked on the wheels.

Tamiya and their Tire caps and other manufacturers and us pancar guys in Europe who call rubber sleeved foamies caps disagree.

Cool, didn't realize the continental differences. You have any shots of the tires you are talking about?

Unknown Manufacturer:

I really like these only because they match up to the Prolines so well! The one on the yellow rim is in really good shape.

My second favorite Grand Prix.

The Yellow one looks to be a Tamiya Lunchbox/pumpkin wheel. I would like to find a set of road tires like that for my lunchbox?

[Johnboy72]

Yeah I have a bunch of Lunchbox parts as this is what the KRP car uses for a rear axle. The majority of the rims were Tamiya as well. The fronts are too, they just cut them and narrowed them down. Sometimes on the left rear too. I'll try to get some pics up after christmas.

JB, I wanted to know more on the GP tires and alum wheels so I called Randy again the tires did come from England and were used in 1/8 racing and the gentleman that made the wheels was in Colorado and has since passed on....JB are ya still in the Military or did ya ETS yet? Thanks JohnnySr

[Johnboy72]

Thanks for the info Johnny. Yeah, I'm still in the military trying to stick it out for the long haul. Already past halfway but damn if these sensitive soldiers and politics are killing me! Hard to be an NCO when you can't cuss or even touch a soldier. Some of these kids need to be smacked around! All they do is complain and whine. Oh well, back on topic. lol.
