Big wheel cars that have wheels with diameters of 24″, 26″, and 28″ have tires that are currently made specifically for various weather conditions which require the tires to have tread on the face of the tire, but nothing regarding high performance or racing applications. This invention will give the rear of the car more traction and safer stopping/steering performances during high performance applications that include DOT approved tires for public highways, and non-DOT approved tires for racing applications on raceways.

The tire (11) for a passenger vehicle comprises an axially narrowest working layer (26), the axially narrowest working layer (26) having an axial width T2 expressed in mm. The tire is adapted to be mounted (10) on a mounting support (100) comprising a rim (200) having a rim width A expressed in mm and a rim width code according to the ETRTO 2019 Standards Manual. The tire (11) has a load index L1 such that LI≥LI′+1, LI′ being the load index of an EXTRA LOAD tire of the same size according to the ETRTO 2019 Standards Manual. The ratio T2/A is such that T2/A≤1.00. The rim width code is equal to the measuring rim width code for the tire size minus 0.5.

A pneumatic tire having a carcass and a belt reinforcing structure, the belt reinforcing structure comprising: a zigzag belt reinforcing structure formed of a strip of reinforcement cords, the strip of reinforcement cords being inclined at 5 to 30 degrees relative to the centerplane of the tire extending in alternation to turnaround points at each lateral edge, wherein the strip of cords is formed from two different cords made of different materials.

A non directional pneumatic tire is provided for an agricultural irrigation system. The tire includes first and second side walls and a radially outer wall defining an internal inflation chamber. A non directional tread pattern is defined on the tire and includes a plurality of longitudinal protrusions positioned substantially parallel to a rotational axis of the tire. The longitudinal protrusions are arranged in first and second rows extending from the first and second side walls toward and across the equatorial plane of the tire. The longitudinal protrusions of the first and second rows circumferentially alternate with each other and there is a circumferential spacing between adjacent longitudinal protrusions at the equatorial plane so that no portion of one longitudinal protrusion circumferentially coincides with or overlaps another.

An outer surface of a tire can include a tread surface and a pair of side surfaces. A contour line of the tread surface can include a center arc, a pair of middle arcs, a pair of side arcs, and a pair of shoulder arcs. A contour line of each side surface can be connected to the shoulder arc. A position, on the outer surface, corresponding to a ground-contact end obtained by applying a load that is 80% of a standardized load, to the tire in a standardized state, and bringing the tire into contact with a flat surface is a reference ground-contact position, and a boundary between the shoulder arc and the side arc is a reference boundary. The reference boundary can be located axially outward of the reference ground-contact position. A ratio of a distance in an axial direction from an equator plane to the reference boundary to a distance in the axial direction from the equator plane to a tread reference end TE can be not less than 0.94 and not greater than 0.98.

Provided is a pneumatic tire having at least one carcass layer as a skeleton extending in toroidal shape over a pair of bead portions, at least one belt layer and a tread disposed on an outer side in the radial direction of a crown portion of the carcass. In a tire section in the widthwise direction in state where the tire is assembled to an application rim, ratio BD/BW of radius difference BD between radius at a center portion and radius at an end portion in the widthwise direction of an innermost layer of the belt layer, to width BW of the innermost layer, ranges from 0.01 to 0.04, and ratio TD/TW of radius difference TD between radius at a center portion and radius at an end portion of the tread in the widthwise direction of a tread ground surface, to tread ground-contact width TW, satisfies BD/BW<TD/TW.
