Alliance 365 Agri-Star II R-1W Radial Agricultural Tire

The Alliance 365 Agri-Star II R-1W is a premium radial agricultural tire line engineered for the rigorous demands of modern, high-horsepower farming operations. Designed for rear drive axle applications on two- and four-wheel drive tractors, combines, and MFWA machines, this tire line delivers a winning combination of advanced tread technology, robust radial construction, and superior soil protection — purpose-built for operators who need dependable performance across the full range of field and road conditions.

At the core of the Agri-Star II is Alliance's proprietary Stratified Layer Technology (SLT) — a dual-layer lug construction that reinforces each tread bar from the base up. The stiffer bottom layer supports the upper tread layer to prevent lug squirm and heat buildup, while the deep upper layer maintains aggressive R-1W traction contact. This stepped lug design preserves consistent ground contact even as the tire wears, so traction performance is maintained throughout the full usable life of the tire.

Key Features:

• Stratified Layer Technology (SLT): Dual-layer lug construction reduces flex and heat buildup while sustaining effective traction even on significantly worn tread
• Deep R-1W Lug Tread Pattern: Aggressive asymmetric lug design with center-overlapping lugs delivers maximum soil penetration and grip across soft, muddy, and hard-packed field conditions
• Excellent Self-Cleaning Capability: Optimized lug count with elastic lug construction efficiently expels mud and debris for consistent traction throughout long field days
• Large Footprint, Low Compaction: High tire volume combined with low inflation pressure creates a broad, even contact patch that maximizes traction while minimizing soil compaction — protecting long-term field productivity
• Cut-, Chip- and Stubble-Resistant Compound: Advanced tread rubber resists field damage and delivers long wear life and outstanding cost-per-hour value in tough agricultural environments
• Reinforced Radial Carcass: Strong carcass with rigid belts resists punctures, abrasions, and field damage while providing a smooth, compliant ride on equipment without traditional suspension systems
• Smooth On-Road Performance: Overlapping lug centers and radial flex characteristics deliver a quiet, comfortable ride during road transport between fields — ideal for machines that regularly travel on pavement
• Available with VF Technology: Select variants feature Very High Flexion (VF) technology, enabling up to 40% higher rated load capacity at the same inflation pressure as a standard radial — or equivalent load capacity at significantly reduced inflation pressure for less soil disturbance
• High-Speed Rated: D-speed rated for high-speed tractor drive axle applications, supporting both intensive field work and efficient road transport
• Seven-Year Warranty: Backed by Alliance's seven-year tire warranty, reflecting the brand's confidence in the long-term durability of this product line

Manufactured by Alliance Tire Group (ATG), a Yokohama Off-Highway Tires company with a global presence in over 120 countries, the 365 Agri-Star II R-1W line is available across a wide range of sizes — including standard radial and VF variants — to suit diverse rear drive axle and tractor applications. Whether working heavy soil in the field or hauling loads on the road, the Agri-Star II delivers the traction, soil care, and durability that modern farming demands.
