@raijkeraijke Yes, you’re right, that was a bit vague, to call it square-ish…What I meant, was, that from front view, the ‘lines’ should be horizontal and vertical, so the section is not tapered. So you need to select each straight ‘line’ and scale it along the X or Z axis to make it vertical or horizontal.
This still sounds like a horrible explanation, but sometimes it can be hard to explain something just in text;)
Anyway, I made your tire segment non-tapered and corrected the Bezier Circle, but you have some work left to do, for one, the tire is way to broad now….
