Description

• 385/65R22.5: This indicates the tire size. Here’s a breakdown:
  • 385: The width of the tire section in millimeters (mm).
  • 65: The aspect ratio, which is the height of the sidewall as a percentage of the width (65% in this case).
  • R: Indicates a radial tire construction.
  • 22.5: The rim diameter in inches.
• 164K: This represents the load rating of the tire. The load rating indicates the maximum weight that the tire can carry at a specific inflation pressure. In this case, 164K means the tire can carry up to 164 kg (361,590 lbs) at the designated pressure.
• 24PR: This refers to the ply rating, which is an indication of the tire’s construction. A higher ply rating indicates a higher load capacity and a more robust tire. 24PR signifies that the tire has 24 plies of material in the sidewall construction, making it an extremely strong tire designed for heavy loads.
• TL: Means the tire is tubeless, relying on an airtight seal between the tire and the rim to hold air, instead of an inner tube.
• 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):

• Excellent durability and long tread life: The 24PR ply rating and deep tread pattern suggest the Hankook Smart Flex TH31 is designed for harsh environments, off-road applications, and heavy loads [1, 2]. This can help to reduce operating costs for truck fleets that operate in these conditions.
• 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.
• Off-road capability: The deep tread pattern with large grooves and sipes is designed for good traction on loose surfaces like gravel, dirt, and mud [2].
• Improved handling: The tread pattern design is also said to improve handling on wet and dry roads [2].

Overall, the 385/65R22.5 Hankook Smart Flex TH31 164K 24PR TL M+S 3PMSF appears to be a heavy-duty, all-season tire that is well-suited for off-road applications, severe weather conditions, and long hauls. It is a good choice for truck fleets that prioritize durability, long tread life, and good performance in off-road and wintry conditions.
