In modern agricultural production, tires are not just the "feet" of farm machinery—they are a key factor determining operational efficiency, fuel costs, and soil health. SUNDOM is committed to delivering high-performance, highly reliable agricultural tire solutions to farmers worldwide. The SUNDOM 520/85R42 R-1W radial agricultural tire, a premium product engineered specifically for the rear axle of high-horsepower tractors, combines exceptional traction and durability to help every farmer conquer the field and reap a bountiful harvest.
1. Radial Construction – A Comprehensive Performance Upgrade
The 520/85R42 features an advanced radial tire structure, with carcass plies arranged radially and reinforced by high-strength belt layers. This design delivers superior elasticity, wear resistance, lower rolling resistance, and better grip compared to conventional bias tires. The radial construction provides a larger footprint, effectively reducing soil compaction and slippage while improving traction efficiency and fuel economy. Compared with bias tires, radial tires can save approximately 5.26% in fuel and increase work efficiency by 5.2%. The flexible sidewall design also significantly enhances ride comfort, reducing fatigue during long hours of operation.
2. R-1W Deep Tread – Confident Performance in Tough Conditions
The SUNDOM 520/85R42 is equipped with the classic R-1W deep tread pattern, a globally recognized high-traction design in the agricultural tire industry. Its key advantages include:
· Powerful Traction: Specially deepened tread blocks with optimized angles ensure strong grip even in soft, wet fields, significantly reducing slippage and efficiently transferring engine power to the ground.
· Excellent Self-Cleaning: The unique tread structure quickly sheds mud after operation in wet conditions, keeping the tread clean for consistent traction performance.
· Cut and Abrasion Resistance: A specialized wear-resistant compound effectively resists punctures from sharp stones and crop stubble in the field, extending tire service life.
· Low Soil Compaction: The low-profile design combined with radial construction reduces soil compaction, helping prevent soil hardening and protecting farmland quality.
3. 520/85R42 Size – Ideal for Mainstream High-Horsepower Tractors
The 520/85R42 (equivalent to 20.8R42) is one of the mainstream rear tire sizes for medium to large tractors. With a 42-inch rim diameter and a section width of 516 mm, this tire offers excellent load-carrying capacity and footprint, making it especially suitable for high-horsepower tractors (above 200 HP) in heavy-duty operations such as plowing, harrowing, and seeding. Whether in dry or paddy fields, the SUNDOM 520/85R42 R-1W delivers reliable performance that farmers can trust.
4. SUNDOM Quality Commitment
SUNDOM adheres to a craftsmanship philosophy in every tire we make. From compound formulation and structural design to production processes, the 520/85R42 R-1W undergoes strict quality control and rigorous testing to ensure reliable performance under harsh field conditions. We believe that only tires proven on the land are the true partners that farmers need.
