The SEYOUN SYT912 315/80R22.5 is a premium heavy-duty commercial radial tire engineered specifically for fleets operating in high-demand Regional Hauling and intercity transport logistics. Featuring an aggressive, high-saturation lug block design, the SYT912 is optimized for Driver and Trailer positions, delivering exceptional forward traction, superior load-carrying stability, and maximized original tread life. Built with an advanced anti-wear compound and a reinforced heavy-ply steel carcass, this model actively suppresses irregular wear and stone retention, significantly driving down the total operating cost per mile for commercial fleet operators.
SYT912 Tread Pattern DesignThe tread incorporates massive, interconnected center blocks that maximize the rubber-to-road contact patch. When fitted on the Driver Axle, it easily channels massive engine torque into absolute forward biting grip, ensuring short braking distances and preventing slippage under heavy payloads on intercity highways.
Engineered with a high-tensile steel cord casing, the SYT912 features outstanding durability due to the strengthened tire carcass which effectively prevents irregular wear and structural casing deformation. This robust internal architecture allows the tire to consistently handle maximum payload limits on trailing trailer axles while preserving a pristine casing suited for multiple retreads.
The optimized wide transversal tread blocks are paired with dynamic stone-ejection walls. It forces stones and gravel to be kicked out continuously during rotation, preventing sharp debris from drilling into the steel belts, thereby safeguarding the tire from unexpected air-loss or catastrophic punctures.

1.High Wear Resistance 4.Long Mileage Performance
Special tread compound design extends tire life and reduces cost per km. Optimized footprint distbution promotes even wear and longer mileage.
2.Strong Traction Performance 5.Fuel Saving
Deep grooves and block design provide excellent grip on wet and dey roads. Low roling resistance design helps reduce fuel consumption.
3.High Load Capacity 6.Safe & Reliable
Reinforced carcass structure enpures high load capacity and durabllity. 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
