Abstract
A pneumatic radial tire includes a carcass structure having a pair of sidewalls and a crown, a pair of beads, a tread, a belt structure, and a plurality of reinforcing hoops. The plurality of spaced apart reinforcing hoops are disposed intermediate the crown of the carcass structure and the tread, and are formed of a rigid material coated in an elastomeric material. The plurality of reinforcing hoops includes a pair of outer reinforcing hoops disposed adjacent the sidewalls of the carcass, and an at least one inner reinforcing hoop disposed between the outer reinforcing hoops.
Claims16
A pneumatic radial tire comprising:
- a carcass formed of at least one body ply and sidewalls;
- a tread disposed radially outwardly of the at least one body ply, the tread including a top tread portion, a cushion portion, a base tread portion, and a cushion filler portion, the base tread portion disposed between and contacting the cushion portion and the cushion filler portion of the tread;
- at least one belt disposed radially intermediate the at least one body ply and the cushion portion of the tread;
- and
- a plurality of reinforcing hoops embedded within the tread and disposed radially intermediate the cushion portion and the top tread portion of the tread, each of the reinforcing hoops including both a metal ring and non-metal reinforcing fibers, wherein the base tread portion has grooves, the reinforcing hoops are disposed within the grooves of the base tread portion, and a portion of the cushion filler extends into the grooves between the reinforcing hoops and the base tread portion.
A pneumatic radial tire comprising:
- a carcass formed of at least one body ply and sidewalls;
- a tread disposed radially outwardly of the at least one body ply, the tread including a top tread portion and a cushion portion;
- at least one belt disposed radially intermediate the at least one body ply and the cushion portion of the tread;
- and
- a plurality of reinforcing hoops embedded within the tread and disposed radially intermediate the cushion portion and the top tread portion of the tread, each of the reinforcing hoops including both a metal ring and non-metal reinforcing fibers;
- wherein the plurality of reinforcing hoops includes a pair of outer reinforcing hoops disposed adjacent to the sidewalls, at least one inner reinforcing hoop is disposed axially intermediate the pair of outer reinforcing hoops, and a radial thickness of the outer hoops is less than a radial thickness of the at least one inner hoop.
