litst, This is your tire but I moved some points in the spline room to make the profile of the tire lower. That;s why I'k so confused. I didn't use the torus preset. I tried to make a tire follwing you direction and it's solid. I don't still don't understand how you made it, mine end up being silod. I use a circle preset, symmetrical envelope, and add points, but it ends up being a solid cylinder, not a hollow tire.What am I doing wrong? I want a tire that looks like what I've got above, but smooth, please help. Thanks kaom
