About this tire

Bridgestone calls it “a touring bias with a long sales record, built on all-round performance matched to what riders actually need.” Silica in the compound for wet performance, and a sport-sact rear. ★ The Japanese lineup has shrunk to two front and three rear sizes; almost none of the small diameters that made it a staple are left ★

Across the six axes, Wet・Life・Comfort sits at 4 and Dry・Warm-up・Sport at 3. The six numbers land close together: an even set-up. Of the 101 tires in the Standard group, 16 carry 4 for Wet. 2 front sizes and 3 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.
