Abstract
A tire has a tread pattern with superior performance characteristics. The tread pattern includes a generally oval shaped lug pattern having sidewalls that are of a variable angle. The sidewalls are also formed at an angle with respect to a vertical axis. The transitions between the sidewalls, as well as between the sidewalls and the oval shaped lug pattern have rounded edges to reduce stress components. A base of the lug is generally rectangular with convex sides.

A tire comprising a lug pattern, each lug of the lug pattern having a substantially oval shaped contacting surface and a plurality of variable angle sidewalls extending from a base to the substantially oval shaped contacting surface.
A tire comprising a plurality of same shaped lugs, each of the plurality of same shaped lugs are offset with respect to one another in adjacent rows and includes a substantially rectangular base with convex sides and a substantially oval shaped contacting surface, a plurality of sidewalls extend from the substantially rectangular base to the substantially oval shaped contacting surface.
The lire as claimed in claim 111, wherein a length to width ratio of each of the same shaped lugs is approximately from 1.28:1 to 1.4:1.
A tire comprising:
- a plurality of lugs, each of the lugs of the plurality of lugs comprising:
- a substantially rectangular base with convex sides;
- a substantially oval shaped contacting surface;
- and
- a plurality of tapered and variable angle sidewalls extending from the substantially rectangular base to the substantially oval shaped contacting surface,
- wherein a transition between each of the tapered and variable angle sidewalls for each of the plurality of lugs is devoid of sharp edges, and
- a groove bottom positioned between adjacent lugs of the plurality of lugs having a rounded portion.
