The new Bridgestone M860 all-position on/off-highway radials are said to deliver outstanding tread life with excellent retreadability as well. They’re engineered for refuse and other severe-service trucks, and can carry extremely heavy loads even at sustained 65-mph highway speeds.

The M860 uses a wider tread and a wider casing that spreads the load over a larger area, distributing footprint pressure for longer tread life. This wider design also means the M860 can haul up to 20,000 lb on steer axles.

Superior bead durability is said to come from its two-ply nylon plus one steel chafer bead area, even under high brake heat and heavy loads. To protect the casing, thick
abrasion-resistant sidewall ribs fight curbing damage. If one set of the protector ribs is worn away, the tire can be flipped for continued protection.

The M860 tire uses a tough tread compound to resist cuts, chips and tears. To enhance casing life, stone rejector platforms in the center grooves help prevent trapped stones from pushing into the tread grooves and piercing the belt layer, which can damage belts and expose them to rust. The grooves on the outside of the tread surface are designed with a special angle to combat stone retention that can lead to casing damage and loss of retreadability.

The tire uses four steel belts and an all-steel casing so it can be retreaded for any axle position.
