The SEYOUN SYT620 is a high-mileage commercial radial truck tire engineered exclusively for long-haul highway operations on steer and trailer axles. Manufactured with advanced steel-belt technology and premium wear-resistant raw materials, the SYT620 delivers exceptional fuel economy, flawless steering tracking, and unmatched resistance to irregular wear. It stands as the definitive choice for long-distance fleets looking to drop their operational fuel costs and maximize asset life under varying highway conditions.
SYT620 Tread Pattern DesignThe SYT620 is built on a streamlined 5-rib layout separated by four high-capacity longitudinal straight grooves. This design distributes vehicle load perfectly across the footprint, reducing running temperatures and lowering rolling resistance to the absolute minimum. This delivers outstanding fuel efficiency and noticeable fuel savings for large commercial fleets.
Steer and trailer axles are naturally prone to aggressive shoulder scrubbing during lane changes and tight turning. The SYT620 counters this with solid, continuous closed outer shoulders. By bracing the tire against lateral stress, it effectively eliminates irregular rib wear, shoulder wiping, and scalloping, keeping the tread uniform for thousands of miles.
The inner tread ribs are intricately engineered with micro-sipes and wave-contoured edges. These channels create thousands of microscopic biting edges that actively slice through standing water films, generating strong wet and dry road traction, high handling stability, and reduced commercial braking distances.

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
