About this file
This document is a product information sheet from Mack Trucks, Inc. for the Bridgestone M870 High-Scrub All-Position Radial tire, updated on March 30, 2021. The document provides technical specifications and details for tires specifically engineered for refuse, high-scrub, and short-haul applications.
The Bridgestone M870 tire is designed for urban waste collection vehicles, featuring innovations such as a four-rib pattern, stone rejector platforms, angled grooves, and a solid shoulder design. The tire offers a projected 30% increase in wear life compared to the previous M860A model. Two tire sizes are specified (315/80R22.5 and 425/65R22.5), both with a load rating of L and a maximum road speed of 68 MPH. The tire includes advanced technologies like cooling fin technology, improved sidewall protector ribs, a wide belt design, and a new bead compound to enhance durability, puncture resistance, and retreadability. The tire is rated to support heavy loads up to 20,000 pounds on steer axles and meets the 3 Peak Mountain Snow Flake (3PMSF) criteria for snow traction performance.

BRIDGESTONE M870
Affects: 900- Front Tires, 901- Rear Tires, MA5- Auxiliary Tires Updated: March 30, 2021
Engineered Specifically for Refuse, High-Scrub, Short-Haul Applications.
The Bridgestone M870 All-Position Radial tire has improvements designed specifically for urban waste collection. Casing features such as Cooling Fin technology, Sidewall Protectors and new Stone Rejectors are designed to increase casing durability, making it more retreadable than ever. A new tread pattern and optimized footprint contribute to longer wear for an increase of 30% over the Bridgestone M860A.*
* Wear results based on field testing in waste fleet applications in the U.S. The improvement in treadwear is the projected mileage based on the Bridgestone internal proprietary field test result around 60% worn stage. Actual results will vary depending on several factors such as tire size, operating conditions, maintenance, road conditions, and driving style.
