Abstract
A pneumatic tire mountable and usable on a rim can include a tread portion having a ground contact surface, and a pair of sidewall portions extending inward in a tire radial direction from both sides of the tread portion in a tire axial direction. The rim can have a rim diameter of 10 to 18 inches. The rim can have a rim width that is 78% to 99% of a cross-sectional width of the tire. A ratio of a cross-sectional height of the tire to the cross-sectional width can be 30% to 45%. Each sidewall portion can have a buttress portion located on an outer side in the tire radial direction. A protector protruding outward in the tire axial direction can be on at least one of a pair of the buttress portions.
Claims19
A pneumatic tire that is mountable and usable on a rim, the pneumatic tire comprising:
- a tread portion having a ground contact surface;
- and
- a pair of sidewall portions extending inward in a tire radial direction from both sides of the tread portion in a tire axial direction, wherein
- the rim has a rim diameter RD of 10 to 18 inches,
- the rim has a rim width RW that is 78% to 99% of a cross-sectional width SW of the tire,
- a ratio SH/SW of a cross-sectional height SH of the tire to the cross-sectional width SW is 30% to 45%,
- each sidewall portion of the pair of sidewall portions has a buttress portion on an outer side in the tire radial direction, and
- a protector protruding outward in the tire axial direction is on at least one of the buttress portions of the pair of sidewall portions.
A pneumatic tire that is mountable and usable on a rim, the pneumatic tire comprising:
- a tread portion having a ground contact surface;
- a pair of sidewall portions extending inward in a tire radial direction from both sides of the tread portion in a tire axial direction;
- and
- a carcass extending from the tread portion to a bead portion inward of each sidewall portion of the pair of sidewall portions in the tire radial direction, wherein
- the rim has a rim diameter of 10 to 18 inches,
- the rim has a rim width that is 78% to 99% of a cross-sectional width of the tire,
- a ratio of a cross-sectional height of the tire to the cross-sectional width of the tire is 30% to 45%,
- each sidewall portion of the pair of sidewall portions has a buttress portion on an outer side in the tire radial direction relative to a tire maximum width position on the sidewall portion,
- a protector protruding outward in the tire axial direction is on at least one of the buttress portions of the pair of sidewall portions,
- the protector has an outer end located outward, in the tire axial direction, of the tire maximum width position on each of the sidewall portions excluding the protector,
- a plurality of carcass plies of the carcass each have a turned-up portion with an outer end, and
- the outer end of each of the turned-up portions is inward, in the tire radial direction, of the protector.
