The SEYOUN SY-S099 motorcycle tire is a premium-engineered, high-performance sport tyre custom-built for modern high-speed scooters, urban street motorcycles, and high-velocity electric mobility platforms. Designed to merge aggressive visual styling with severe tarmac engineering, this high-speed tyre showcases an advanced directional lightning-V profile that dramatically optimizes straight-line tracking and steering precision during sustained highway velocity.
Manufactured with industry-leading automated thermal curing machinery and an enriched silica wear-resistant rubber compound, the SY-S099 maintains a highly dynamic contact patch that maximizes mechanical road adhesion on both sun-baked asphalt and rain-slicked concrete. Developed with a definitive focus on zero-delay hydrodynamic fluid excavation, crisp low-fatigue cornering feedback, and prolonged tread mileage life, it stands as the premier high-margin tire asset for global wholesalers and commercial distributors alike.
SY-S099 Tread Pattern Design
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
