2024 International LT — Tire Size & Pressure

Quick Answer

• OEM Tire Size: Varies significantly by specific configuration and gross vehicle weight rating (GVWR). Common sizes include 11R22.5, 295/75R22.5, and 285/75R24.5.
• Recommended Cold Tire Pressure (Door Placard): Refer to the tire placard located on the driver's side door jamb for exact pressures. Pressures will vary based on tire size, axle loads, and specific vehicle configuration, often ranging from 90 to 120 psi.
• Bolt Pattern: Typically 10-hole, 285.75mm bolt circle diameter (10x285.75mm).
• Wheel Size: Primarily 22.5-inch and 24.5-inch diameter. Widths commonly 8.25 inches.
• Load Index/Speed Rating: Load indexes are very high, often 144 (5,510 lbs) to 150 (7,385 lbs) or more, with speed ratings typically L (75 mph) or M (81 mph) for commercial applications.
• Spare Tire Size: Generally matches one of the driven axle tire sizes.
• TPMS Frequency: 433 MHz is common for newer commercial vehicles, but always verify with the specific truck's build sheet or a diagnostic tool.

Tire Sizes by Trim

The International LT series is a highly customizable heavy-duty truck, and "trim levels" in the traditional passenger vehicle sense don't directly apply to tire sizes. Instead, tire sizes are determined by factors such as:

• Gross Vehicle Weight Rating (GVWR) and Gross Axle Weight Rating (GAWR): Heavier applications require tires with higher load capacities.
• Engine & Drivetrain: Affects weight distribution and overall load.
• Application (e.g., long-haul, regional, vocational): Different applications may favor certain tire characteristics (e.g., fuel efficiency, traction).
• Fleet Specifications: Large fleets often have specific tire programs.

However, here's a general overview of common tire size categories for the 2024 International LT:

It is crucial to consult the tire placard on the specific vehicle for the exact OEM tire sizes.

Recommended Replacement Tires

Choosing replacement tires for a heavy-duty truck like the International LT depends heavily on the application, desired characteristics (e.g., fuel efficiency, mileage, traction in specific conditions), and budget. Many tire manufacturers offer dedicated lines for steer, drive, and trailer positions. Here are some popular options across different price tiers:

• Premium Tier (Long Haul/Fuel Efficiency Focused):
  • Michelin X Line Energy Series: Known for excellent fuel economy and long tread life. (Price: $$$$)
  • Goodyear Fuel Max Series: Another top contender for reduced rolling resistance and fuel savings. (Price: $$$$)
• Mid-Tier (Balanced Performance/Regional Haul):
  • Bridgestone Ecopia Series: Offers a good balance of fuel efficiency and durability for diverse applications. (Price: $$$)
  • Continental Hybrid Series: Designed for versatile performance in both line haul and regional service. (Price: $$$)
• Value Tier (Cost-Effective/General Use):
  • Sumitomo ST719/ST727: Reliable performance for steer and drive positions at a competitive price point. (Price: $$)
  • Double Coin RLB400/RT606: Popular for their durability and retreadability, offering good value. (Price: $$)

Always ensure replacement tires have an equivalent or greater load index and speed rating as the OEM specified tires.

When to Inflate to Max Load PSI

For heavy-duty trucks like the 2024 International LT, adhering to the recommended cold tire pressure on the door placard is paramount. This pressure is calculated to support the maximum anticipated axle loads for the vehicle
