Bolar, they look great, I didn't think about putting them on a Trexler rim, but it's a good idea if you not a scale guy. I plan to use them for a 48" Super Cub using the rim they came on. How well do they work on rough ground? I imagine there is little bounce. My gear will have scale suspension which should work well.

It's too bad the wheel makers don't make a foam wheel that looks like the Trexlers instead of the flat sided ones. Does anyone know what type of foam they use for making these tires? If we could get some wider we could make our own balloon foamy tires.
