• 385/65R22.5: This indicates the tire size. Here’s a breakdown of the specifics:
  • 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 refers to a load capacity of up to 164 kg (361,590 lbs).
• 20PR: This refers to the ply rating of the tire. Ply rating is an indicator of the number of rubber layers in the tire sidewall, though it is not a direct representation of the number of plies [4, 5]. A higher ply rating generally indicates a higher load capacity and a more robust tire construction.
• 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):

• Durability and long tread life: The tread pattern of the Continental Hybrid HT3+ appears to be deep and designed for long hauls [1, 2, 3]. This tread pattern design, combined with the 20PR ply rating, suggests a robust construction that can reduce operating costs for truck fleets.
• Versatility for all-season performance: The M+S and 3PMSF markings on the tire signify its ability to handle various weather conditions, including light winter snow and ice [1, 2, 3]. While it may not be ideal for severe snow conditions, it provides better performance in all-weather conditions compared to all-season tires without the 3PMSF designation.
• Fuel efficiency: The Continental Hybrid HT3+ is said to be fuel-efficient, due to a tread pattern design that reduces rolling resistance [2, 3]. This can help to reduce fuel costs for truck fleets.
• Improved handling for trailers: The tread pattern design may also improve handling performance for trailers [1, 2, 3].
• High load capacity: The 164K load rating and 20PR ply rating indicate the tire is suitable for trailers carrying heavy loads [1, 4, 5].

Overall, the 385/65R22.5 Continental Hybrid HT3+ 164K 20PR TL M+S 3PMSF appears to be a versatile trailer tire that offers durability, long tread life, good performance in all-weather conditions including light winter snow, fuel efficiency, improved handling, and a high load capacity. It is a good choice for heavy-duty trucks operating on regional routes.
