The SEYOUN SY-S003A is an extra-heavy-duty motorcycle and cargo tricycle tire engineered for high-speed straight-line stability, extreme payload capability, and long-lasting tread wear on challenging road surfaces. Designed to fit large 12-inch and 13-inch heavy-vehicle wheel dimensions—including 4.00-12, 4.50-12, 5.00-12, 5.50-13, and 6.00-13—this tire serves as a powerful solution for commercial transport fleets, cargo tricycles, and heavy delivery motorcycles.
Featuring a heavy-block pattern with a continuous central zig-zag channel, the SY-S003A balances effortless water dispersion with maximum tire-to-ground contact pressure under heavy load. Its reinforced multi-ply carcass resists structural distortion under high weights, protecting against punctures and lateral blowouts. For global B2B tire distributors, regional wholesalers, and fleet suppliers, the SY-S003A delivers high-margin potential and unmatched industrial reliability.
SY-S003A Tread Pattern DesignContinuous Center Zig-Zag Hydro-Channel : A continuous center channel cuts through standing water film to maintain directional alignment, providing reliable tracking stability at cruising speeds.
Trapezoidal Interlocking Lug Blocks: Sturdy block-shaped lugs on either side absorb heavy acceleration, torque, and braking forces without premature rubber tearing or chunking.
Transverse High-Volume Water Evacuation : Deep lateral channels push mud, debris, and water outward, ensuring self-cleaning capability and high traction on wet asphalt or dirt roads.
Heavy-Duty Multi-Ply Reinforced Carcass : Built with high-density carcass plies to support heavy cargo payloads while dampening impacts from potholes and rough pavement.
1.Excellent Wear Resistance 4.Strong Load Capacity
Special tread compound ensures even wear and longer tire life. Reinforced carcass provides excellent load-bearing performance.
2.Enhanced Wet Traction 5.Long Mileage Performance
Deep grooves and slopes design provide superior grip on wet roads. Optimized foot print distribution promotes even wear and longer mileage.
3.High-Speed Stability 6.Safe & Reliable
Optimiced pattern and structure enoure stable performance at high speeds. Superior stablity and braking performance ensure driving safety.
As a rubber production combined with steel and other materials, tires can be eroded slowly by chemicals, oil, heat, and ozone. The main raw materials of tires include natural rubber and synthetic rubber from petroleum products, so tires exposed to high temperatures heat or fire sources will cause fires that are difficult to extinguish.
Tires should be stored in a cool, dry, clean warehouse to prevent rain, dust, and light. Tires should be placed away from electric generators/motors and sources of heat such as hot pipes. Storage surfaces should be clean and free of grease, gasoline, diesel fuel, or other substances that can deteriorate the rubber. Please rotate tires every month if they are upright in storage. If tires have to be stored outdoors, the place should be:
Improper storage can damage your tires in ways that may not be visible and can lead to a
failure resulting in serious personal injury or death.
Avoid mixing with trucks transporting oil and chemicals. Tire transport vehicles should be equipped with adequate fire equipment. When using a forklift to handle truck tires, install the correct accessories for the forklift, such as tire stackers, tire handlers, etc. Any improper handling ways may cause damage to the tire. For example, the keen-edged forks can bring damage to the bead if you use the forklift without proper accessories.
Proper mounting procedures must be followed or sudden tire destruction, personal injury or death may result. Tire mounting must be done only by personnel trained, supervised and equipped according to local regulations and following the processes requirement of the industries. Always inflate tire/rim assembly in an approved safety cage or equivalent restraining device
