Why Are Seyoun Wide Tread Tires Selling Well?

Wide tread tyre is one of the three special designed Seyoun TBR series. Why Seyoun get involved in production of wide tread tyre? and how can Seyoun produce a piece of good wide tread tyre?

Part One: Advantages of Wide-Tread Truck and Bus Tires

Wide-tread tires, commonly referred to as “wide-base tires” or “single wide tires,” are single wide tires designed to replace traditional dual tire configurations (i.e., two tires mounted on a single rim). Their primary advantages are as follows:

Weight Reduction and Fuel Efficiency

Reduced Vehicle Weight: A single wide-base tire with a steel rim typically weighs less than two conventional tires with two steel rims. For example, this can reduce axle weight by approximately 100 kilograms. In the freight industry, where weight restrictions are stringent, lighter vehicles mean greater cargo capacity, directly boosting profitability.

Reduced Rolling Resistance: Optimized tread design and advanced rubber compounds effectively lower rolling resistance. As a major contributor to fuel consumption, reduced resistance translates directly to lower fuel usage, typically yielding 2%-5% fuel savings—delivering substantial long-term benefits.

Superior Stability and Safety

Enhanced handling stability: A wider tread provides greater ground contact area, improving traction and lateral stability. This is particularly beneficial during cornering, on wet surfaces, and at high speeds, effectively reducing the risk of skidding and enhancing overall vehicle control.

Stronger rollover resistance: A lower center of gravity and increased stability provide vehicles—especially trailers—with superior rollover resistance, enhancing road safety.

Eliminates Twin-Tire Issues: Traditional twin-tire configurations may suffer uneven force distribution due to inconsistent tire pressure, leading to abnormal wear or even blowouts. Wide single tires completely eliminate interference and stone-trapping issues between tires.

Long-Lasting Performance & Low Maintenance

More Even Wear: Without the abnormal wear issues between twin tires, wide tires typically wear more uniformly, extending their lifespan.

Reduced tire count: Fewer total tires per vehicle (e.g., from 18 to 10) means fewer units requiring maintenance and replacement, lowering routine upkeep, tire-changing time, and financial costs.

Environmental Sustainability & Comfort

Reduced material usage: Manufacturing one wide-base tire requires less rubber and materials than producing two standard tires, making it more eco-friendly.

Noise Reduction: Advanced wide-base tire designs help minimize road noise during operation.

Smoother Ride: The larger contact patch provides a more stable ride, enhancing driving comfort.

Part Two: Essential Elements for Manufacturing a High-Quality Wide-Base Tire

Producing a high-performance, reliable wide-base tire is a complex systems engineering endeavor requiring the seamless integration of multiple cutting-edge technologies and precision processes. Core elements include:

Advanced Tire Structure Design and Simulation Technology

Tread Pattern Design: The shape of tread blocks, groove depth, and directional orientation are critical, directly impacting water drainage, traction, heat dissipation, and noise control. Simulation optimization using Computational Fluid Dynamics (CFD) is essential.

Profile Design: The cross-sectional profile determines ground pressure distribution. Optimized pressure distribution prevents uneven wear, ensures uniform tread consumption, and extends service life.

Structural Mechanics Design: Tools like Finite Element Analysis (FEA) precisely calculate and optimize stress distribution in carcass cords, belt layers, and other structural materials. This ensures structural integrity and stability under load, rolling, and steering forces while maintaining flexibility to minimize heat generation.

High-Performance Raw Materials

Rubber Compound: This is the core proprietary technology in tire manufacturing. Dedicated formulations must be developed to balance multiple performance attributes:

Low Heat Generation Compound: Excessive heat buildup during prolonged operation is the primary cause of truck and bus tire blowouts. Low-heat rubber compounds are essential.

High Abrasion Resistance Compound: Ensures exceptionally long mileage.

Cut and Tear Resistance Compound: Enhances the tread's ability to withstand impacts from road obstacles.

Casing Materials: High-strength steel cords are used for the belt layers and carcass, providing robust support. Material strength, toughness, and bonding properties are critical.

Precision Manufacturing Processes

Precise Molding Process: Wide-base tire blanks are larger and heavier, demanding exceptional precision and automation from molding machines. Each material layer (liner, carcass, belt plies, tread) must be perfectly aligned and tightly bonded; any deviation leads to product defects.

Vulcanization Process: Vulcanization is the critical step imparting the tire's final shape and performance. It requires extremely precise control of temperature, pressure, and time within the vulcanization retort to ensure complete rubber cross-linking and uniform curing throughout the tire.

Rigorous Quality Control and Testing

Full Process Inspection: From raw material intake to finished product shipment, every stage undergoes stringent quality checks, including X-ray inspection (examining internal cord arrangement, presence of bubbles or impurities), uniformity testing, and dynamic balancing tests.

Durability Testing: Tires must pass indoor drum tests far exceeding real-world conditions, simulating extreme loads, high speeds, and long-distance driving to validate their endurance and reliability.

On-Road Testing: Finally, tires are mounted on vehicles for comprehensive real-world road testing across various road surfaces and climatic conditions to fully evaluate their performance.

Seyoun have professional engineers team with 20 year more experience in rubber and tyre. The material like raw rubber is from SEA, and equipments from Itay and Japan.

The plant processing is under MESNAC' smart manufacturing industry 4.0 system, which is most advanced manufacturing and management in tyre industry. The combination of labour and machine inspection team contribute a lot to the tyre quality and high-rate of finished products.

In summary, a high-quality wide-tread truck and bus tire is the result of the synergistic integration of top-tier Design, Material, Process, and Test (DMPT). Manufacturers must continuously invest in R&D and innovation across these four dimensions to produce outstanding products that are safe, fuel-efficient, and exceptionally durable.
