Tires may be used on multiple vehicle types (e.g., trucks, cars, trailers, etc.) to help travel under multiple on road/off road conditions. For instance, using trucks as an example, specific designs of tires may be used to help the truck travel under normal conditions, mud conditions, snow conditions, rain conditions, as well as other conditions.
In one example implementation, a tire may include but is not limited to a plurality of block patterns, wherein the plurality of block patterns may repeat around a circumference of the tire. The tire may further include a three dimensional chambered groove in the plurality of block patterns. The tire may further include a plurality of independent pattern blocks.
One or more of the following example features may be included. The plurality of block patterns may have an S shape. The plurality of block patterns may be located between a left shoulder and a right shoulder, and wherein one reinforcing rib of the plurality of reinforcing ribs may connect two shoulder blocks. The three dimensional chambered groove may be located in a middle portion of each block pattern of the plurality of block patterns. The three dimensional chambered groove may be most narrow in a middle portion of the three dimensional chambered groove. The plurality of independent pattern blocks may have a wedge shape. The wedge shape may be widest at a top part of the wedge shape and narrowest at a bottom part of the wedge shape. The tire may further include a plurality of reinforcing ribs. The plurality of reinforcing ribs may be located at a bottom portion of a shoulder groove. The tire may further include a sidewall pattern with a thickness between 2.0 mm-4.0 mm. An angle of the pattern block may be between 5°-45°. The sidewall pattern may include at least 3 layers of high modulus low shrinkage polymer cords. The tire may further include a belt steel wire and a double-layer crown belt. The tire may be a bias tire. The tire may be a truck and bus radial tire.
In another example implementation, a tire may include but is not limited to a plurality of block patterns, wherein the plurality of block patterns may repeat around a circumference of the tire.

The tire may further include a plurality of independent pattern blocks. The tire may further include a plurality of reinforcing ribs located at a bottom portion of a shoulder groove, wherein one reinforcing rib of the plurality of reinforcing ribs may connect two shoulder blocks.
One or more of the following example features may be included. The plurality of block patterns may have an S shape.

The details of one or more example implementations are set forth in the accompanying drawings and the description below. Other possible example features and/or possible example advantages will become apparent from the description, the drawings, and the claims. Some implementations may not have those possible example features and/or possible example advantages, and such possible example features and/or possible example advantages may not necessarily be required of some implementations.
Like reference symbols in the various drawings indicate like elements.
Tires may be used on multiple vehicle types (e.g., trucks, cars, trailers, etc.) to help travel under multiple on road/off road conditions. For instance, using trucks as an example, specific designs of tires may be used to help the truck travel on paved or non-paved roads under normal conditions, mud conditions, snow conditions, rain conditions, as well as other conditions. As will be discussed below, known tires may have problems, such as insufficient grip, wheel skidding, insufficient climbing ability, poor passing performance on non-paved roads, such as muddy roads and rocky roads, easy puncture of the tread and easy blasting of the sidewall in environments such as gravel roads, mountain roads, and mining areas. As will be discussed below, the tire of the present disclosure may advantageously provide better grip performance, improve the passing performance of non-paved roads, provide higher puncture resistance and improve tire safety performance.
As discussed above and referring also at least to the example implementations of
In some implementations, a tire may include a plurality of block patterns, wherein the plurality of block patterns may repeat around a circumference of the tire. For example, and referring at least to the example implementation of
In some implementations, an angle of the pattern block may be between 5°-45° (e.g., 30° ˜35°). For instance, through the special pattern design, the optimal angle of pattern block 102 obtained from many experiments (e.g., 3D modeling analysis and finite element FEA analysis) may be selected to improve the grip performance and passing performance of tire 100. It will be appreciated that slight variations in the angle of pattern block 102 may be used without departing from the scope of the present disclosure.
In some implementations, the tire may further include a three dimensional chambered groove in the plurality of block patterns. For instance, tire 100 may include a three dimensional chambered groove (e.g., chambered groove 106). In some implementations, chambered groove 106 may be located in a middle portion of each block pattern 102 of the plurality of block patterns. For example, as shown in
In some implementations, tire 100 may further include a plurality of reinforcing ribs. For example, as shown in
In some implementations, tire 100 may further include a plurality of independent pattern blocks. For instance, as shown in
In some implementations, tire 100 may further include a sidewall pattern with a thickness between, e.g., 2.00 mm-4.00 mm. For instance, and referring at least to the example implementation of
In some implementations, sidewall pattern 114 may include at least 3 layers of high modulus low shrinkage polymer cords. For example, some designs of the present disclosure may use 3 layers of 1500D/2 E100 high modulus low shrinkage polyester cord, whereas ordinary tires generally use 1 layer or 2 layers. Advantageously, the strengthened and deepened sidewall pattern design and the use of 3 layers of high modulus low shrinkage polymer cords may thus increase the sidewall strength, thereby addressing the example problem of having the sidewall too easily burst. The advantages of high modulus and low shrinkage polyester cord fabrics may be, e.g.: low elongation, high initial modulus, good dimensional stability, impact resistance around at least 4 times higher than nylon, and excellent heat resistance. In some implementations, tire 100 may further include a belt steel wire and a double-layer crown belt. Some example designs may use 2 layers of ultra-high-strength belt steel wire F70 (2+2×0.35ST), and whereas most common tires generally use HT steel wire, the design of the present disclosure may use ST type steel wire. Advantageously, the use of ultra-high-strength belt steel wire and double-layer crown belt may be used to strengthen the performance of tire tread puncture resistance. Compared with HT type steel wire, ST type steel wire has higher tensile strength, lighter weight and easier adhesion to rubber, so it can improve tire safety performance.
In some implementations, tire 100 may be a bias tire. For example, tire 100 may be a radial tire that allows the sidewall and the tread to function as two independent features of tire 100. A bias tire may consist of multiple rubber plies overlapping each other. The crown and sidewalls may be interdependent, and thus, performance of non-paved roads may be increased by using bias tires with large blocks as shown.
In some implementations, tire 100 may be a truck and bus radial tire (also referred to herein as a TBR tire). For instance, the improvement of tire grip and performance may be addressed by adopting a TBR structure and bias tire pattern.
