The SEYOUN SYT903 is a ultra-deep all-steel radial drive tire precision-built for heavy commercial trucks demanding extreme torque and ultimate cut resistance in severe off-road, stone quarry, and mining conditions. Featuring an innovative flat solid smooth center tread coupled with alternating trapezoidal shoulder lugs, the SYT903 serves as an impenetrable shield against severe stone-drilling while effectively suppressing heat buildup during high-load operations. It is the definitive investment for severe-duty fleet operations aiming to completely eliminate tread chunking and maximize heavy logistics asset uptime.
SYT903 Tread Pattern DesignUnlike standard traction tires whose open blocks easily get torn apart by jagged granite, the SYT903 features a continuous, solid smooth center core. This seamless rubber shield provides unmatched premium cut and puncture resistance, completely eliminating stone-retention and stone-drilling hazards into the underlying steel belts.
To provide massive torque transmission for heavy-duty drive axles, the tire is engineered with deep, alternating trapezoidal pockets along both shoulders. These rugged traction blocks bite deeply into unpaved tracks, gravel, and loose soils, guaranteeing continuous forward traction and excellent climbing power when pulling fully loaded tippers out of steep mining ramps.
Built on an optimized high-tensile steel belt package designed for 11.00R20 and 12.00R20 specifications, the rugged casing prevents structural deformation under extreme payloads. The robust inner architecture absorbs direct impacts from sharp blasting debris, keeping the carcass pristine for multiple profitable retreads.

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
