Tire with tread traction in snow and dry improved

摘要

This invention relates generally to tires having treads that have a configuration and/or properties for providing suitable snow and dry traction, and, more specifically, to a tire that has a tread that has a maximum value for sipe density in the contact patch, a minimum value for lateral groove density in the contact patch, and a minimum value for the longitudinal contact surface ratio. In certain embodiments, the pitch length of pitches or repeating units of tread geometry along the circumferential direction of the tire is within a certain range and the tread depth is below a specified value. Tires with treads having a configuration that falls within these design parameters exhibit a desirably good level of snow and dry traction.
