Bridgestone said its new M860 all-position on/off-highway radials deliver outstanding tread life, durable beads and sidewalls and retread ability. M860 radials are engineered for refuse and other severe-service trucks, and to carry extremely heavy loads, even at sustained 65-mph highway speeds.
M860 uses a wider tread and a wider casing that spreads the load over a larger area, distributing footprint pressure for longer tread life, the company said. This wider design also means M860 can haul heavy refuse loads, up to 20,000 lbs. on steer axles.
It is engineered for superior bead durability and tire life. Its two-ply nylon plus 1 steel chafer helps strengthen the 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, promoting outstanding wear for start-stop driving that’s typical for refuse pickup routes and other severe-service hauling, the company said.
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 on/off-highway tire uses four steel belts and an all-steel casing so it can be retreaded for any axle position, the company said. It uses computer-designed blocks and notches to bite into soft surfaces.
