Why choose the MICHELIN ROADBIB tire?

The solution for heavy road use.

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

Fuel Economy

A wide footprint combined with a shallow tread provides low rolling resistance and reduced fuel consumption.

Tire Life

Extraordinary longevity

+20% more rubber to the ground vs. MICHELIN® MachXBib®. Exclusive design: new tread pattern and directional tires.

Comfort

Great comfort

Full central rib improves casing stability and comfort on roads. Reduced space between patterns (compared to traditional sculptures) helps limits cabin vibration and tire noise.

Handling

Handling & Safety

Outstanding driving quality thanks to a new sculpture similar to that of a truck tire. Excellent tire adhesion on wet roads thanks to vertical evacuation paths.

MICHELIN ROADBIB Technology

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.
