Abstract
A tire tread is provided having a layered design that includes bridged and unbridged circumferential grooves during earlier stages of tread life while transverse and unbridged circumferential grooves are provided at later stages of tread life. Together, the combination of grooves can provide desired wet adherence performance without unacceptable compromises of tread wear and/or rolling resistance. Pockets can also be provided at the end of the transverse grooves to increase the volume available for receipt of water during wet traction.
