A pneumatic tire having improved snow traction and tread wear, and improved noise and handling properties, has 80 to 105 pitches and a sipe density of 1. 0 to 1. 1. The tire has a substantially rounded footprint, and has a footprint shape factor (FSF) of 1. 2 to 1. 5. The tire has an open central and intermediate region, as compared to the shoulder region, and has lateral groove depths that vary from 50% to 100% of the tread depth, wherein the shallower grooves are disposed toward the central and intermediate regions of the tire.
A pneumatic tire having improved snow traction and treadwear, and improved noise and handling properties, has 80 to 105 pitches and a sipe density of 1. 0 to 1. 1. The tire has a square footprint, and has a footprint shape factor (FSF) of 1. 0 to 1. 25. The tire has an open central and intermediate region, as compared to the shoulder region, and has lateral groove depths that vary from 50% to 100% of the tread depth; wherein the shallower grooves are disposed toward the central and intermediate regions of the tire.
