A tire with improved snow performance and dry braking performance is provided that has at least one lateral groove with a chamfer found where the groove intersects the circumference of the tire. In some cases, a second chamfer is found opposite first chamfer on the groove. In most cases, a plurality of similarly configured lateral grooves with chamfers is found along the circumference of the tire. Typically, the width of the lateral groove is approximately 2 to 4 mm, and preferably between 2.6 and 3.6 mm. Also the angle the chamfer forms with the tangent of the circumference of the tire may be approximately 45 degrees. The angle the sweep path of the lateral groove forms with the lateral direction of the tire ranges from approximately 0 to 45 degrees. |
