Galaxy EARTHPRO 45 BIAS R-1 Agricultural Tractor Tire

The Galaxy EarthPro 45 Bias R-1 is a premium bias-ply agricultural tractor tire engineered by Alliance Tire Group — a Yokohama Rubber Company division — to deliver professional-grade field performance with a practical total cost of ownership. Purpose-built for rear-drive tractor applications, the EarthPro 45 line pairs proven bias-ply construction with a distinctive 45-degree lug geometry to excel across a wide range of farming environments, from open field work to road transport and everyday around-the-farm tasks.

Key Features:

• Optimized 45-Degree Lug Angle: The defining characteristic of the EarthPro 45 design, the 45-degree tread lug angle maximizes traction and self-cleaning performance in the field while supporting smooth, stable roadability on gravel and pavement.
• Longer Lugs for Increased Ground Contact: Compared to traditional 23-degree lug designs, the longer lugs put more rubber on the ground, delivering improved ride comfort and enhanced pulling power during demanding field operations.
• Wide Nose Bar Construction: A specially engineered wide nose bar reduces lug wear, extends overall tire service life, and ensures smoother performance during road travel between job sites.
• Life-Extending Rubber Compound: A low-wear compound with additional rubber at the lug center and an evenly distributed tie bar stabilizes the lugs and significantly reduces total cost of ownership over the tire's working life.
• Penetration and Puncture Resistance: An additional rubber layer beneath the tread improves resistance to cuts, chips, and penetration from field debris and rough terrain.
• Reinforced Sidewall Protection: Tough sidewalls provide deflection stability and strong resistance to damage from rocks, stumps, and other external hazards common in agricultural environments.
• Lug Base Crack Prevention: Engineered lug angles and radius geometry minimize stress cracking at the lug base, preserving the tire's structural integrity across its full working life.
• Proven Bias-Ply Architecture: Time-tested bias-ply construction delivers flexible, impact-resistant performance ideal for uneven terrain, loader work, and applications where a cost-effective alternative to radial tires is preferred.
• Wide Size Selection: The EarthPro 45 line is offered in a broad selection of sizes to fit front and rear axles across a wide spectrum of farm tractors.
