2015 Volvo VNL Tire Size & Pressure Guide

Quick Answer

• OEM Tire Size: 11R22.5 (steer and drive axles), 295/75R22.5 (steer and drive axles)
• Recommended Cold Tire Pressure:
  • Steer Axle: 100-110 psi
  • Drive Axles: 90-105 psi
• Bolt Pattern: 10-lug on 285.75mm (10x285.75)
• Wheel Size: 22.5 x 8.25 inches
• Load Index/Speed Rating: Varies by specific tire model, but typically J (62 mph) or L (75 mph) speed ratings are common, with load capacities suitable for heavy truck applications.
• Spare Tire Size: Same as OEM, typically 11R22.5 or 295/75R22.5
• TPMS Frequency: 433 MHz (common for heavy-duty trucks)

Tire Sizes by Trim

The Volvo VNL series is a heavy-duty truck with various configurations, and tire sizes are generally consistent across different "trims" or applications within the VNL line, focusing more on axle weight ratings and intended use rather than passenger car "trims." The most common OEM tire sizes are:

• 11R22.5: A very common heavy-duty truck tire size, offering a good balance of load capacity, durability, and availability.
• 295/75R22.5: Another popular option, often providing a slightly different footprint and potentially contributing to fuel efficiency in some applications.

Recommended Replacement Tires

When replacing tires on your 2015 Volvo VNL, it's crucial to select tires designed for heavy-duty truck applications, considering factors like load capacity, durability, fuel efficiency, and traction for your specific driving conditions. Here are a few popular options:

• Michelin X Line Energy Z (Steer) / D (Drive): A premium choice known for excellent fuel efficiency and long tread life. These tires are designed to minimize rolling resistance, making them ideal for long-haul operations. (Premium Price Tier)
• Goodyear Fuel Max S (Steer) / D (Drive): Another strong contender for fuel efficiency and mileage. Goodyear offers a wide range of heavy-duty truck tires engineered for various applications, and the Fuel Max series is a popular choice for over-the-road hauling. (Premium Price Tier)
• Bridgestone M799 (Steer) / M773 (Drive): Known for their durability and strong performance in regional and line-haul applications. Bridgestone tires are a reliable choice for mixed-service and long-haul trucks, offering good wear characteristics. (Mid-Premium Price Tier)
• Continental Hybrid HS3 (Steer) / HD3 (Drive): These tires are designed to offer a balance of fuel efficiency and long mileage. Continental provides robust options for heavy-duty trucks, focusing on durability and all-around performance. (Mid-Premium Price Tier)
• Sumitomo ST719 (Steer) / ST900 (Drive): A more budget-friendly option that still delivers solid performance for heavy-duty applications. Sumitomo tires are known for their value and reliable performance in various trucking environments. (Mid-Range Price Tier)

When to Inflate to Max Load PSI

For a heavy-duty truck like the 2015 Volvo VNL, understanding tire pressure is critical for safety, tire longevity, and fuel efficiency. Unlike passenger vehicles, heavy trucks often operate at varying loads, and tire pressure needs to be adjusted accordingly. The "recommended cold tire pressure" on your door placard (or more accurately, the Federal Certification Label or tire information decal) is a starting point, often set for the Gross Vehicle Weight Rating (GVWR) or Gross Axle Weight Rating (GAWR).

Always refer to the tire manufacturer's load and inflation tables for your specific tires. These tables provide the precise inflation pressure required for a given load on each axle.

You should inflate your tires to the maximum load PSI (or closer to it) when:
