Approximate geometry. Real mounted width varies by rim, pressure, and manufacturer (roughly ±4% per 0.5" off the tire's measuring rim). Contact patch length is a visual proxy — actual footprint depends on load, pressure, and compound.
Fitment guidance is based on standard motorcycle tire manufacturer rim-width charts (Michelin, Pirelli, Dunlop, Bridgestone). Always confirm with the specific tire's data sheet — some models publish their own approved rim widths.
