Sectional structure of motorcycle tire

摘要: The utility model relates to a sectional structure of motorcycle tire. tire comprises tread part, edge part and bead wherein the consists an upper arc line lower straight line, form obtuse angle, is circumferentially provided with saw-tooth grains, fillet arranged between part. As consisting adopted, generally broken rigidity guaranteed, so that can be better embedded rim, problem separated from rim prevented; in addition, grains are additionally designed on total weight reduced; rounded, stress concentration prevented, strength when runs at state internal pressure decreased, used for locking air-retention performance improved, car reach nearest maintenance point.
