• 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.
• 160K/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, 160K 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:
  • 160K: Up to 160 kg (352,740 lbs)
  • 158L: Up to 158 kg (348,332 lbs)
• 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.
• 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.
• 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.

Features and Benefits (based on information found online):

• Durability and long tread life: The tread pattern of the Goodyear OmniTrac S appears to have a moderately deep lug design with sipes, suggesting it’s designed for a balance between on-road wear and off-road grip [1, 2, 3]. Sipes are small slits or cuts in the tread blocks that improve traction on snow and ice. 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 suggests that the tire can handle both highway and moderate off-road conditions, such as gravel roads or dirt tracks [1, 2, 3]. It is not intended for heavy off-road use.
• Improved Traction in All-Weather Conditions: The M+S 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 M+S designation.
• High Load Capacity: The 160K load rating and 20PR ply rating indicate the tire is suitable for trucks carrying heavy loads [1].

Mounted on Wheel: The image you sent shows the tire mounted on a wheel, which means it is ready to be installed on a truck.

Overall, the 385/65R22.5 Goodyear OmniTrac S 160K/158L TL 20PR M+S appears to be a versatile mixed-service tire that offers durability, long tread life, a balance between on-road and moderate off-road performance, improved traction in all-weather conditions, and a high load capacity. It is a good choice for trucks that operate on a variety of terrains, including highways, gravel roads, and light off-road applications.
