Michelin 69879 XM28 620/70R46 162A8/B Radial Tractor Tire R-1W

The Michelin XM28 (MACHXBIB) 620/70R46 is a large-volume, high-flotation radial agricultural tire engineered for high-horsepower tractors and combines. Designed with a super-flat, wide tread profile and rounded shoulders, this R-1W deep-lug tire delivers outstanding soil protection and minimal ground compaction — critical for preserving field productivity and crop yield.

The XM28's oversized, uniform footprint spreads the load evenly across a large contact area, dramatically reducing soil disturbance. Paired with ultra-low working pressures and a flexible, super-strong radial casing, this tire minimizes slip while maintaining reliable traction and mobility even in adverse or wet field conditions.

Key Features:

• R-1W Deep Lug Tread Pattern — Enhanced traction in wet, muddy, and demanding field conditions
• Super-Flat Wide Footprint — Spreads load evenly to reduce soil compaction and protect field structure
• Rounded Shoulder Design — Minimizes soil disturbance at tread edges during turns
• Low Slip Rate — Reduces power loss and improves fuel efficiency in field operations
• Minimal Rolling Resistance — Supports efficient operation across varied terrain
• Ultra-Low Working Pressures — Enables high-flotation performance with decreased ground pressure
• Uniform Round Construction — Super-strong yet ultra-flexible casing for a smooth, stable ride
• Tubeless (TL) Construction — Ready for modern high-horsepower tractor applications

Rated at 162A8/162B dual load index with a 72/32nds tread depth and an overall diameter of 81.1 inches, the Michelin XM28 is built to perform in the most demanding large-scale agricultural environments. Michelin Part Number: 69879.
