RoadX TOP LINE Technical Optimization of Performance

ENGINEERED FOR UNMATCHED EFFICIENCY AND ENDURANCE

RoadX Tire is redefining what commercial trucking fleets can expect from long- haul performance. The all-new TOP Line tire series—engineered specifically for steer, drive, and trailer positions—delivers industry-leading fuel efficiency, extended wear life, and innovative design tailored to today’s demanding freight operations.

INNOVATION THAT DRIVES SAVINGS

At the core of the TOP Line is EcoPoint³, an exclusive tread compound developed using RoadX’s proprietary Liquid Phase Mixing technology - a world-first in tire manufacturing. This breakthrough allows for ultra-fine silica dispersion, setting a new benchmark for low rolling resistance in truck tire technology. The Liquid Phase Mixing process also lowers energy consumption at the manufacturing level, showing RoadX’s commitment to reduce its carbon footprint and enhance sustainability.

LIGHTER. STRONGER. SMARTER

TOP Line tires also feature our advanced Slim Bead Technology, reducing overall casing weight while further improving rolling resistance—without compromising strength or retreadability.

PRECISION DESIGN FOR EVERY POSITION

Steer and Trailer Tires: All-new tread designs with a wide 230mm footprint and enhanced decoupling grooves for reduced irregular wear and superior mileage performance.

Drive Tire: 240mm wide tread purpose-built to deliver maximum traction, durability, and even wear in high-mileage, long-haul operations.

THE RESULT

Reduced fuel consumption, lower emissions, improved wet traction and mileage for maximum return on investment
