Abstract
A pneumatic tire 1 has a non-symmetric pattern in which a land ratio Lo of an outer tread surface portion To facing towards outside of a vehicle from a tire equator C is set to be larger than a land ratio Li of an inner tread surface pattern Ti facing towards inside of the vehicle from the tire equator C; concave grooves 9 extending substantially in a circumferential direction of the tire are formed in an outer tire side region Yo that is located between a grounding end Eo of the outer tread surface portion To and a maximum width position M of the tire facing towards outside of the vehicle.
Claims5
A pneumatic tire,
- having a tread surface that is comprised of an inner tread surface portion that faces inward of an inner side of a vehicle from a tire equator and of an outer tread surface portion that faces outward of an outer side of the vehicle from the tire equator, and
- having a non-symmetric pattern in which a land ratio of a tread pattern of the outer tread surface portion is larger than a land ratio of a tread pattern of the inner tread surface portion,
- wherein concave grooves extending substantially in a circumferential direction of the tire are formed on an outer tire side region formed between a grounding end of the outer tread surface portion and a maximum width position of the tire facing outward of the vehicle.
