Tire sizes by trim

The Freightliner M2 106 is a highly versatile and customizable medium-duty truck, meaning "trims" in the traditional passenger vehicle sense don't directly apply. Instead, tire sizes are specified based on the Gross Vehicle Weight Rating (GVWR), axle configurations, and intended application. Common OEM tire sizes include:

Note: Other specialized tire sizes may be available depending on the vocational upfit and specific axle specifications.

Recommended replacement tires

When choosing replacement tires for your Freightliner M2 106, consider the tire's intended use (e.g., highway, regional, city, mixed-use), expected loads, and desired tread life. Here are a few popular options across different price tiers, suitable for various applications:

• Michelin X Line Energy Z (Premium): A premium steer tire known for its fuel efficiency and long tread life, well-suited for long-haul and regional applications. Expect to pay in the $500-$700+ range per tire.
• Goodyear Endurance LHD (Premium): A popular drive tire offering excellent traction and durability for long-haul and regional applications. Priced similarly to Michelin.
• Continental Hybrid HS3 (Mid-Range): A versatile steer tire designed for regional and P&D (pickup and delivery) applications, offering a good balance of fuel efficiency and handling. Typically in the $400-$600 range per tire.
• Firestone FS591 (Mid-Range): A solid steer tire choice for regional and urban applications, offering good wear characteristics and wet traction. Expect prices in the $350-$550 range.
• General Grabber OA 2 (Value): A more budget-friendly all-position tire suitable for mixed-service applications, providing good durability. Generally, in the $300-$450 range.

Prices can vary significantly based on the retailer, promotions, and specific tire size.

When to inflate to max load psi

For heavy-duty trucks like the Freightliner M2 106, it is rarely recommended to inflate tires to their maximum sidewall psi unless the vehicle is consistently operating at or very near its maximum permissible axle weight.

Instead, you should always consult your vehicle's tire placard (typically found on the door jamb or in the glove box) for the recommended cold tire inflation pressures. This placard provides pressures specifically tailored to your truck's configuration and Gross Vehicle Weight Rating (GVWR) or Gross Axle Weight Rating (GAWR).
