Kyosho optima +5mm offset wheels for std 2.2" tires

thingiverse

I designed this wheel for my kyosho optima re-release buggy. I wanted to use modern 2.2" tires, but the optima wheels have an unusual offset and the buggy ends up 10mm narrower when standard 2.2" wheels are fitted. These rims have a 4.7mm offset, allowing you to fit modern tires without adversely affecting the handling or styling of the buggy. These rims are designed for 2.2" 4WD FRONT tires. Modern 4WD rear tires are too wide for the optima. The optima has slightly longer axles than most buggies which allowed me to make the centre of the wheels a bit thicker for added strength. They are standard 12mm hex. If you must have wide rear wheels, I've also uploaded another .stl for wide 2.2" tires as well. I haven't personally printed those so I can't be sure if they'll fit. Happy racing! Edit: I deliberately smashed one of these with a rubber mallet today. It was very strong. Probably stronger than the genuine kyosho product. Another edit: I've run 15 or 20 batteries through my optima with these wheels, and they're holding up well. The outside bead has cracked off a bit, but as long as the tyres are securely glued, it doesn't really matter. They've sucked up quite a few huge cart-wheeling crashes without breaking! :) I'm sure the rims will last as long as the tires do.
