Not sure where the right place to post this question is on HRW, so I'm dropping it here.
I've made a few attempts at casting my own Urethane tires. I've tried Smooth-On Vytaflex 40 shore and 20 shore, and use their black pigment to dye them.
I've had success with 3D printing tire molds, a few different ways. However, I haven't been satisfied with the grip of the tires. The 40 Shore tires seemed to have almost a slick surface to them. If you dragged them across the track by hand there was no adhesion at all. So I went softer and tried the 20 Shore. The 20 Shore tires perform a little better on the car, but still feel slick to me.
Does anyone have any additives to put into the Urethane to get them to develop some level of adhesion when cured?
