TOUGH URBAN TIRES

Bridgestone Greatec M845 wide-base tire

Bridgestone has announced a pair of new Bridgestone tires for heavy-duty urban use. The Greatec M845 wide-base and M860A high-scrub all-position radials employ new technologies to the tough demands of urban environments — like stop and go driving, oil and chemical residue, potholes, metal plates, and cracked paving – in applications such as waste collection.

The new design innovations in these tires are said to help prolong tire life and retreadability.

The M860A reflects improvements made to the Bridgestone M860, with a new compound that improves wear performance leading to longer life, the company says. It’s also engineered with a wider belt package that aims to enhance casing durability, making it more retreadable for a longer period.

The Greatec M845 is available in a new size for Bridgestone, 455/55R22.5. The wide-base design allows for heavier loads, requiring fewer trips and more money on the bottom line.

It features next-generation WavedBelt technology to reduce irregular shoulder wear. Other elements include: stone-rejector platforms; optimized groove shape to increase durability and enhance retreadability; an aggressive block pattern that promotes wet traction; and a continuous shoulder design for reduced rolling resistance. Other features, says Bridgestone, include, special tread compounds, extra-deep and extra-wide tread, tough sidewall protection, optimized belt package, and patented Turn-In ply design.
        
The M860A tire was engineered specifically for refuse, high-scrub, and short-haul applications, featuring a special compound that improves wear performance and lifespan while a wider belt package enhances casing durability and increases retreadability. Key elements include: aggressive blocks to bite into soft surfaces for better traction; stone-rejector platforms; angled grooves to promote wet traction; solid shoulder design to evenly distribute weight and torque to fight irregular wear and block squirm for even wear. Other features, according to Bridgestone, include a long-lasting tread designed to spread load over a larger area for long life, a special cap compound, sidewall protector ribs, wide casing and wide belt design, and reinforced bead.

The M860A will be available in June and the Greatec M845 in July.
