Abstract
A VF rated radial implement tire is provided utilizing a steel belted radial TBR tire body design which can be utilized in existing TBR cavity molds, and modifying the tire to have a ribbed implement tread pattern. The tire is designed for operation at relatively low inflation pressures with relatively high wall flexibility. Thus an agricultural implement tire is provided having higher load carrying capability than similarly sized conventional bias ply agricultural implement tires.
Claims22
A pneumatic agricultural implement tire, comprising:
- a circumferential tread portion including a ribbed implement tread pattern having a plurality of relatively wide parallel circumferential ribs separated by relatively narrow circumferential grooves;
- a pair of bead portions;
- a steel reinforced radial carcass ply extending between and wrapped around the bead portions;
- at least three steel reinforced circumferentially extending belts disposed between the carcass ply and the circumferential tread portion;
- the tire being sized to fit on one of a nominal 19.5 inch or 22.5 inch or 24.5 inch diameter rim;
- the tire having a sidewall deflection at rated load and inflation pressure of at least about 27%;
- and
- the tire having a VF load rating in accordance with the standards of the Tire and Rim Association.
A pneumatic agricultural implement tire, comprising:
- a tire body of TBR construction including at least one steel reinforced body ply and at least three circumferential steel reinforced belts, the tire body being constructed to fit on one of a nominal 19.5 inch or 22.5 inch or 24.5 inch diameter rim;
- a tread portion on the tire body, the tread portion including a ribbed implement tread pattern;
- and
- the tire having a maximum load rating at a maximum inflation pressure resulting in a sidewall deflection of at least about 27%.
A method of manufacturing a pneumatic agricultural implement tire, the method comprising:
- providing a tire body of TBR construction including at least one steel reinforced body ply and at least three circumferential steel reinforced belts, the tire body being constructed to fit on one of a nominal 19.5 inch or 22.5 inch or 24.5 inch diameter rim;
- providing a tread portion on the tire body, the tread portion including a ribbed implement tread pattern;
- and
- constructing the tire to have a maximum load rating at a maximum inflation pressure resulting in a sidewall deflection of at least about 27%.
