I would guess that it has to do with the tread tension. A rounded top with a flat bottom may leave the tread too loose. The triangle keeps it taught.

- hsienmaneja 8y agoNote: taut (pulled tightly) and taught (past tense of teach) are homophones
- Amygaz 8y agoConsidering that this is a rather a rounded triangle, I doubt it has anything to do with tightness, and more with convenience, esthetic. A symmetrical displacement is also slightly less constraining in term of keeping the overall circumference/periphery (i.e. less deformation). A better design would have been to flatten the wheel into an more oblong or even an egg shape, like snowmobiles or tanks have. However, it requires more mechanical displacement and adjustements.
- JshWright 8y ago"Better" is meaningless in isolation. The design you propose is better in some aspects, but likely not in the areas the designers of this wheel are optimizing for (simplicity, reliability, etc)
