Alliance 354 AGRIFLEX IF R-1W Radial Agricultural Rear Tractor Tire

The Alliance 354 AGRIFLEX IF is an advanced Improved Flexion (IF) radial rear tractor tire engineered for the demands of modern agricultural operations. Part of Alliance's industry-leading Agriflex family — a comprehensive range of IF and VF tires designed to cover every machine on the farm — the 354 AGRIFLEX IF delivers exceptional load-carrying performance, outstanding field traction, and meaningful soil protection. Alliance, a brand of Yokohama Off-Highway Tires, brings decades of agricultural tire engineering expertise to this line, giving operators a solution that increases productivity while protecting the soil for future seasons.

Improved Flexion (IF) Technology

At the heart of this tire is Alliance's Improved Flexion technology. IF-rated tires are engineered to carry the same load as a standard radial tractor tire at up to 20% lower inflation pressure, or carry up to 20% more load at the same inflation pressure. Running at reduced field pressure expands the tire's footprint, distributing machine weight more evenly across the soil surface and significantly reducing compaction — protecting one of the farm's most valuable long-term assets.

Key Features:

• Improved Flexion (IF) Technology — Carry up to 20% more load at standard pressure, or run at lower pressure for the same load to minimize soil compaction and protect field conditions
• Steel-Belted Radial Construction — State-of-the-art materials and steel-belted design provide uniform ground pressure distribution, superior puncture protection, and long service life
• R-1W Lug Design — Stronger lugs than standard row crop tires, with an enhanced shape delivering superior traction and excellent self-cleaning characteristics in soft, muddy, and loose terrain
• Larger Tire Footprint — Reduced-pressure operation creates a wider, more uniform contact patch that distributes machine weight evenly and limits damage to soil structure
• Puncture and Damage Resistance — Steel belts and reinforced rubber compound provide enhanced protection against cuts, chips, and punctures in demanding field conditions
• Self-Cleaning Tread Pattern — Optimized lug geometry and high void ratio prevent mud and debris retention, maintaining consistent grip across varying terrain
• Reduced Road Noise and Improved Comfort — Enhanced lug shape minimizes noise and vibration during road travel for a smoother, more comfortable operator experience
• Fuel Efficiency — Lower rolling resistance and reduced wheel slip contribute to lower fuel consumption and greater overall operational productivity
• D Speed Rating — Rated for road travel at speeds up to 40 mph, enabling efficient field-to-field transitions
• 10-Year Workmanship & Materials Warranty — Backed by Alliance's long-term commitment to tire quality and durability, plus a field hazard and stubble damage warranty

The Alliance 354 AGRIFLEX IF is a trusted fitment for rear axles of utility tractors and self-propelled sprayers — particularly those employed in row crop operations.
