Pro Tips for Identification:
Format Swap: Sizes like 4.10/3.50-4 and 3.50/4.10-4 are usually identical; the order of width vs. height just varies by manufacturer.
Flat-Free Options: Many of these sizes are available as "Solid Polyurethane" (Flat-Free). They are great for areas with nails or thorns but offer less cushioning than pneumatic (air-filled) tires.
OD vs. Rim: Always distinguish between the Outer Diameter (e.g., "13x" or "15x") and the Rim Size (e.g., "-6"). A 13x5.00-6 and a 15x6.00-6 both fit a 6-inch rim, but the latter is much taller.
