Description

• 295/80R22.5: This is the tire size designation.
  • 295: The width of the tire section in millimeters (mm).
  • 80: The aspect ratio, which is the height of the sidewall as a percentage of the width (80% in this case).
  • R: Indicates a radial tire construction.
  • 22.5: The rim diameter in inches.
• 154/149M: This is the load rating and speed rating of the tire. The load rating indicates the maximum weight that the tire can carry at a specific inflation pressure. In this case, the tire has two load ratings:
  • 154: Up to 75 mph (120 km/h)
  • 149: Up to 65 mph (104 km/h) The speed rating M means the tire is designed for speeds up to 81 mph (130 km/h).
• HL: This stands for “High Load” and signifies that the tire is designed for heavier loads [1].
• TL: This means that the tire is tubeless. Tubeless tires do not have an inner tube and instead rely on an airtight seal between the tire and the rim to hold air.
• M+S: This indicates that the tire is an all-season tire that can be used in moderate snow conditions. The M+S symbol does not mean that the tire is a true winter tire, and it may not perform well in severe snow conditions.
• 3PMSF: This symbol indicates that the tire meets the European winter tire standards for snow and ice performance. This means that the tire has been tested and certified to provide improved traction on snow and ice compared to all-season tires that don’t have this symbol.

Features and Benefits (based on information found online):

• Long tread life: The Pirelli FR:01 Triathlon is designed for extended tread life, which can help to reduce operating costs for truck fleets [1, 2].
• Excellent handling and stability: The tread pattern design is said to improve handling and stability, especially for steer axles [2, 3].
• Good all-season traction with improved winter performance: The M+S and 3PMSF markings on the tire signify its ability to handle various weather conditions, including light winter snow and ice. While it may not be ideal for severe snow conditions, it provides better performance than all-season tires without the 3PMSF designation.
• High load capacity: The “HL” designation and 154/149 load rating indicate the tire’s ability to handle heavy loads, making it suitable for regional haul applications.
• Fuel efficiency: The Pirelli FR:01 Triathlon is also said to be fuel-efficient, which can help to reduce fuel costs for truck fleets [2].

Overall, the 295/80R22.5 Pirelli FR:01 Triathlon 154/149M HL TL M+S 3PMSF appears to be a versatile, all-season tire that is well-suited for steer axles on regional haul trucks. It is a good choice for truck fleets that prioritize long tread life, good handling and stability, fuel efficiency, and all-season performance, including light winter weather.
