Abstract
A tire includes a tread portion provided with a tread profile which is curved in an arcuate shape in a tire meridian section so that the tread portion includes a crown region contacting with the ground during straight running, and a pair of shoulder regions contacting with the ground during cornering by leaning the tire at a certain camber angle. The crown region has a land ratio of not less than 98%, and the shoulder regions have a land ratio of from 85% to 93%. A three-wheeled vehicle has a pair of front wheels and a single rear wheel on which the tire is mounted.
Claims18
A tire comprising:
- a tread portion provided with a tread profile which is curved in an arcuate shape in a tire meridian section so that the tread portion comprises a crown region contacting with the ground during straight running, and a pair of shoulder regions contacting with the ground during cornering by leaning the tire at a certain camber angle, wherein
- the crown region is defined as being centered on a tire equator and ranging 30% of an axial width between tread edges of the tread portion, and the shoulder regions are defined as extending from the respective tread edges to the crown region,
- the crown region is provided with at least one crown slot disposed on the tire equator and extending straight discontinuously along the tire circumferential direction so that the crown region has a land ratio of not less than 98%,
- the shoulder regions have a land ratio of from 85% to 93% and
- an axial width W1 of said at least one crown slot is 2% to 5% of a tread width of the tread portion.
