Optimized for steer axles the Pirelli FR 01 tires offer high fuel efficiency as well as driving comfort. Their wide tread combines with deep grooves to ensure long tread life for high mileage. The optimized profile minimizes tread block movement and reduces heat generation. Dual Layer Tread Compound construction enhances braking and reduces rolling resistance. The sturdy construction of these retreadable tires also improves steering precision. On wet surfaces, the deep grooves effectively drain water from the contact patch to improve safety.
