About this tire

The British-born bias tire the TT100GP grew out of, for older machines. Inch sizes only, and the same sizes work front or rear. ★ Because the size range is identical at both ends, we list every size as both front and rear ★

Across the six axes, Life sits at 4 and Dry・Wet・Warm-up・Sport at 2. Neither extreme nor flat. Of the 7 tires in the Classic group, 3 carry 4 for Life. 4 front sizes and 4 rear, mostly 18-inch.

OE sizes can differ by model year and market — the sidewall of your own bike is the sure reference. This is a Japanese-market lineup; the sizes themselves are international.
