The Sailun WinterPro SW61 is a Nordic winter tire engineered for severe cold climates, focusing on ice and snow traction without studs. Its asymmetric tread design features ultra-dense siping (thousands of micro-grooves) to maximize grip on ice, paired with large shoulder blocks for snow stability. A high-silica compound maintains flexibility in extreme cold (-30°C/-22°F) while resisting heat-induced wear during transient warmer periods. The tread’s dual-zone layout prioritizes lateral grip on outer shoulders and water evacuation via inner grooves. Available in 14”–18” sizes, it targets drivers in regions with prolonged winters and mixed icy conditions.

Features & Benefits

• Hyper-Dense Siping: Over 1,000 micro-grooves per tire enhance ice traction by creating multiple biting edges, maintaining flexibility in sub-zero temperatures.
• Asymmetric Tread Zones: Outer shoulder blocks with Z-shaped grooves resist lateral slip during cornering; inner grooves channel slush and water to reduce hydroplaning.
• 3D Circumferential Grooves: Micro-ridges and stud-like notches within grooves increase friction with compacted snow, improving braking on packed surfaces.
• Reinforced Silica Compound: Fine-dispersed silica balances cold elasticity with tear resistance, extending tread life in freeze-thaw cycles.
• Cross-Cut Technology: Interlocking 3D grooves in tread blocks prevent snow/ice buildup and stabilize the tread during hard braking.

Year Released

Launched in 2017, the WinterPro SW61 remains Sailun’s flagship non-studded winter tire for European and Russian markets.

Regions Availability

This tire is sold primarily in Europe and Russia, regions requiring compliance with ECE R117 snow traction standards.

Vehicle Compatibility

Based on size availability and regional fitment trends:

• Compact cars: Volkswagen Polo, Renault Clio (175/70R14, 185/65R15)
• Sedans/Crossovers: Skoda Octavia, Toyota Corolla (205/55R16, 215/55R17)

• Family SUVs: Nissan Qashqai, Hyundai Tucson (225/55R17, 235/45R18)

Note: Always consult a tire specialist or the vehicle’s manufacturer to confirm fitment.

Final Thoughts

The WinterPro SW61 suits drivers facing harsh, snow-dominated winters where studded tires are restricted. Its ice traction outperforms budget all-season tires but falls short of premium studless alternatives like Nokian Hakkapeliitta R5 on sheer ice. The dense siping excels in wet snow and slush, though tread noise increases on dry pavement—common among winter tires. Limited size availability (many listed as out-of-stock) may restrict accessibility. Ideal for rural and urban Nordic climates, it’s less optimal for mild winters due to accelerated wear above 7°C (45°F). A pragmatic choice for cost-conscious drivers prioritizing snow/ice performance over refinement, particularly in regions like Scandinavia or Siberia.
