Abstract
A pneumatic tire with a shoulder rib and lateral grooves defined in a shoulder rib. A tread and shoulder of the tire are joined along a shoulder edge. The tread includes a circumferential groove defining the shoulder rib, which is adjacent to the tire's shoulder. The lateral grooves, which intersect the shoulder edge, extend laterally across the shoulder rib, but do not intersect the circumferential groove.
Claims11
A pneumatic tire comprising:
- a carcass having an axis of rotation;
- a sidewall centered about said axis of rotation and having a shoulder;
- and
- a tread disposed radially outward of said carcass and joined by said shoulder with said sidewall along an edge, said tread including a circumferential groove defining a first shoulder rib adjacent to said shoulder, said shoulder rib extending across an axial width of said tread and including a plurality of lateral grooves intersecting said edge, said lateral grooves extending laterally across a portion of said axial width so that said lateral grooves do not intersect said circumferential groove.
The pneumatic tire of claim I wherein each of said lateral grooves includes a first groove segment inclined at a first angle relative to said circumferential groove and a second groove segment continuous with said first groove segment, said second groove segment inclined at a second angle relative to said circumferential groove that differs from said first angle.
