Embodiment Construction

[0043] refer to Figure 1A , 1B , 2A and 2B, the tire 10 includes a tread region 12 having a tread pattern of the configuration shown. The tread region 12 includes a pair of outer shoulder rows 14, 16 of tread block elements, an intermediate row of tread block elements 18, 20 located inboard of and adjacent to the respective shoulder rows 14, 16, and the tire and tire The central row of tread block elements 22 on the equatorial centerline of the tread area. The invention is not limited to the tread pattern shown, but has broader application to alternative tread constructions as understood.

[0044] The tread region block elements include adjacent pairs of block elements, such as block elements 24 , 26 . The block elements may, if desired, be of various configurations and geometries, with the pair of block elements having opposite and mutually facing block element sidewalls 28 , 30 separated by a groove 32 . Although the grooves 32 are shown extending in an oblique axial di...

Abstract

A tire tread region has a first block element and a second adjacent block element e spaced apart by a groove and a reinforcement bar is situated within the groove. The reinforcement bar extends between the first and second adjacent blocks at a prescribed inclination angle from a deeper surface end within the groove to a radially more shallow opposite surface end. The inclined surface includes a radially outwardly facing concave surface portion at the radially inward, deeper, inclined surface end.

Description

technical field [0001] The present invention relates generally to treads for tires and, more particularly, to treads having improved frictional energy over the tire footprint. Background technique [0002] The tread area of ​​a tire is designed to achieve a number of goals, including optimizing the tire's fuel mileage and resisting the adverse effects of friction and wear on the tread. Without an optimal tread design, the fuel consumption mileage achieved by the tread may be compromised with the friction and wear performance of the tire tread. Accordingly, it is desirable to provide a way to optimize tire performance (eg, fuel mileage rating) while mitigating the adverse effects of friction over time and wear on the tire tread. Contents of the invention [0003] According to one aspect of the invention, a tire has a tread region in which a first block element is separated from a second adjacent block element by a groove in which a reinforcing rib is located. The rib exte...
