Patent ID: 11077717

Abstract:
A pneumatic tire includes a tread; sidewalls; beads inward of the sidewalls; lug grooves formed in the tread and inclined symmetrically about the equator, an inclination angle α of the lug grooves with respect to the lateral direction being 15°≤α≤45°; and shoulder grooves connecting the lug grooves and inclined in an opposite direction to the lug grooves, a center line of the shoulder grooves at both sides meeting with two of the lug grooves at intersection points. A difference between distances L1, L2 from the equator to the intersection points and a tread width TW satisfy TW×0.03≤|L1−L2|≤TW×0.2. An average value of the distances and the tread width TW satisfy TW×0.15≤(L1+L2)/2≤TW×0.35. A groove area ratio of the tread is from 0.4 to 0.7.
