Truck Trailer Tire Designed for On- and Off-Road Use

The 385/65R22.5 GOODYEAR OMNITRAC T 164K/158L 20PR HL TL 3PMSF is a heavy-duty truck tire designed for trailer axles and offers a balance between on-road and off-road performance [1, 2, 3]. Here’s a breakdown of the information on the sidewall of the tire:

• 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/158L: 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 the load capacity at higher speeds, and 158L refers to the load capacity at lower speeds. Here’s a breakdown of the weight limits:
  • 164K: Up to 164 kg (361,590 lbs)
  • 158L: Up to 158 kg (348,332 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.
• HL: This stands for “Highway Light” and signifies the tire is designed for long-haul use on highways, but also suitable for light off-road applications [1, 2, 3].
• 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.
• 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 Goodyear Omnitrac T appears to have a deep, aggressive lug design, suggesting it’s designed for extended service life and for providing grip on loose surfaces [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 On- and Off-Road Performance: The tread pattern design and the HL designation suggest that the tire can handle both highway and light off-road conditions [1, 2, 3].
• Improved Traction in All-Weather Conditions: The 3PMSF markings on the tire signify its ability to handle various weather conditions, including light winter snow and ice [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.
• High Load Capacity: The 164K load rating and 20PR ply rating indicate the tire is suitable for trailer axles on heavy-duty trucks carrying heavy loads [1].

Overall, the 385/65R22.5 GOODYEAR OMNITRAC T 164K/158L 20PR HL TL 3PMSF appears to be a versatile trailer tire that offers durability, long tread life, good on-road and light off-road performance, improved traction in all-weather conditions, and a high load capacity. It is a good choice for heavy-duty truck trailers operating on a variety of terrains.
