Michelin 39571 CEREXBIB IF 800/65R32 CFO Radial Agricultural Harvester Tire 178A8

The Michelin CEREXBIB IF 800/65R32 CFO 178A8 (Part #39571) is a heavy-duty radial agricultural tire engineered specifically for large combine harvesters and grain carts. Built on Michelin's Increased Flexion (IF) technology platform, this tire is designed to handle high load capacities while operating at lower inflation pressures — directly addressing the dual challenge modern farmers face of maximizing machine performance while protecting valuable soil health.

The IF designation allows this tire to carry the same load as a standard radial tire at significantly reduced inflation pressure, or carry a greater load at the same pressure. The CFO (Cyclic Field Operation) rating means the tire is optimized for the cyclic loading conditions experienced during harvesting operations, where loads fluctuate between field and transport. The result is a wider, flatter contact patch that distributes weight more evenly across the soil surface, reducing compaction depth and helping preserve field productivity season after season.

Key Features:

• IF (Increased Flexion) Technology — Operates at lower inflation pressures versus standard radial tires at equivalent load ratings
• CFO (Cyclic Field Operation) Rated — Engineered for the variable load demands of harvesting equipment in the field and on the road
• Soil Compaction Reduction — Wider footprint spreads load across a greater contact area to protect field soil structure
• R-1W Tread Pattern — Aggressive lug design delivers strong traction in wet and muddy harvesting conditions
• Heavy-Duty Construction — Designed for large combines and grain carts operating under demanding field conditions
• Tubeless (TL) — Tubeless construction for easier maintenance and improved safety
• Load Index 178 / Speed Rating A8 — Rated for extreme load demands at agricultural field speeds

With a tread depth of 57 mm and a recommended operating pressure of approximately 2.4 bar (35 psi), the Michelin CEREXBIB IF 800/65R32 CFO 178A8 delivers the durability and soil-protecting performance that serious farming operations demand. It is an ideal front or drive position tire for large combines, harvesters, and high-capacity grain carts.
