MICHELIN BIBLOAD HARD SURFACE

Non-directional steel-belted radial tire designed for maximum tread life and traction on hard surfaces.

Why choose the MICHELIN BIBLOAD HARD SURFACE tire?

Long life and ride quality.

Explore Michelin technology and innovation designed to support your business, reducing your costs while respecting the environment.

Durability

Proven casing durability

Uses the same proven casing of the XMCL with added reinforcements in the shoulder area for protection.

Traction

Improved lateral traction and grip

Patented diamond lug pattern offers multiple biting edges for traction. Constant traction provided by two sections of lug that are always in contact with the surface.

Comfort

Superior Ride Quality

Radial construction offers a comfortable ride in any condition.

MICHELIN BIBLOAD HARD SURFACE Technology

Diamond tread pattern - Innovative tread pattern for better resistance

Resulting from research and tested in live conditions, the diamond tread pattern mainly consists of independent, bevelled blocks. It provides more contact with the road surface than a bar-based tread pattern. You get more resistance to wear and tear and a smooth ride.

The radial tire - The Michelin innovation that revolutionized tire construction

Sold under the name Michelin X®, this tire was a real breakthrough thanks to its exceptional performance: incredible longevity (it lasted 2 to 4 times longer than a conventional tire), greater safety, and, above all, reduced vehicle fuel consumption.
