2024 International MV Tire Size & Pressure Guide

Quick Answer

• OEM Tire Size: Varies by configuration, common sizes include 11R22.5, 295/75R22.5
• Recommended Cold Tire Pressure (Front/Rear): Refer to door placard, highly dependent on load and axle ratings (typically 85–120 psi for commercial applications)
• Bolt Pattern: 10-lug on 285.75mm (10x285.75)
• Wheel Size: 22.5 x 8.25 inches
• Load Index/Speed Rating: Varies greatly by tire and application; commercial truck tires often have ply ratings instead of traditional load indexes (e.g., 14-ply, 16-ply) and speed ratings are typically L (75 mph) or M (81 mph).
• Spare Tire Size: Matches OEM tire size, if equipped.
• TPMS Frequency: Not typically equipped with passenger vehicle style TPMS; commercial vehicles rely on other monitoring systems or manual checks.

Tire Sizes by Trim

The International MV medium-duty truck is a highly configurable platform, and as such, tire sizes can vary significantly based on the specific chassis, GVWR, application, and axle specifications. While there aren't traditional "trims" in the same way as passenger vehicles, here are common tire sizes you might find:

Axle Configuration	Common Tire Size	Notes
Steer Axle	11R22.5	Common for various applications
Steer Axle	295/75R22.5	Offers a slightly wider footprint
Drive Axle (Single)	11R22.5	Standard dual tire configuration on drive axles
Drive Axle (Single)	295/75R22.5	Often paired with 22.5 x 8.25 wheels
Drive Axle (Super Single)	425/65R22.5	For specific heavy-haul or weight-sensitive applications

It is crucial to always check the specific tire placard on your International MV for the exact OEM tire size and recommended pressure for your vehicle's unique configuration.

Recommended Replacement Tires

When replacing tires on your 2024 International MV, you'll be looking for commercial-grade tires designed for medium-duty truck applications. The best choice will depend on your specific use case (e.g., regional haul, vocational, city delivery) and desired performance characteristics (e.g., fuel efficiency, tread life, traction).

Here are some popular and highly-regarded options, typically available in common sizes like 11R22.5 and 295/75R22.5:

• Michelin X Line Energy Z (Steer) / XDN2 (Drive): These are premium options known for excellent fuel efficiency and long tread life, making them ideal for line haul and regional applications. They come at a higher price tier.
• Goodyear Endurance LHD (Drive) / LHS (Steer): A very popular choice offering a good balance of fuel economy, durability, and traction. These are often a mid-to-high price tier option.
• Bridgestone M799 (Steer/All-Position) / M773 (Drive): Bridgestone offers robust and durable tires suitable for a variety of applications, including vocational. These typically fall into a mid-price tier.
• Continental Hybrid HS3 (Steer) / HD3 (Drive): Known for their consistent performance and durability, suitable for regional and vocational use. These are also in the mid-price tier.
• Firestone FS591 (Steer) / FD691 (Drive): A more budget-friendly option that still delivers reliable performance for many medium-duty applications.

Always ensure the replacement tires meet or exceed the load and speed specifications of the OEM tires listed on your vehicle's placard.

When to Inflate to Max Load PSI

For a heavy-duty or medium-duty truck like the International MV, "max load PSI" (or the maximum cold inflation pressure marked on the tire sidewall) is a critical consideration. Unlike passenger vehicles where this is rarely recommended, commercial trucks often need to be inflated to the maximum recommended cold inflation pressure for the load being carried.

However, it's crucial to understand that you should inflate to the pressure specified by the vehicle manufacturer on the door placard or in the owner's manual for the specific axle load you are carrying, not necessarily the absolute maximum on the tire sidewall unless the axle is at its maximum rated capacity.

• Always consult your vehicle's tire placard: This is the primary source for correct inflation pressures based on your truck's Gross Vehicle Weight Rating (GVWR) and Gross Axle Weight Ratings (GAWR).
• Match pressure to actual load: If your truck is consistently operating at or near its maximum GVWR and GAWR, you will likely need to inflate the tires to the higher end of the recommended pressure range, potentially up to the maximum sidewall pressure, to safely support the load and prevent premature wear or tire failure. Underinflation for heavy loads can lead to excessive heat buildup, tire damage, and even blowouts.
• Underloaded operation: If the truck is running light or empty, inflating to the maximum pressure can lead to a harsher ride, uneven wear (center of tread), and reduced traction. In these cases, it may be appropriate to operate at a lower pressure within the recommended range, as long as it still safely supports the actual axle load.
• Regular checks: Commercial truck tires require diligent monitoring of inflation pressure, ideally before each trip, as even small changes can significantly impact safety, fuel economy, and tire life.

Lug Nut Torque & Pattern

Proper lug nut torque is vital for the safety and longevity of your International MV's wheels. Always use a calibrated torque wrench.

• Lug Nut Torque: For 10-lug commercial wheels (22.5-inch), the typical torque specification is 450–500 ft-lbs (610–678 Nm). Always refer to the latest service manual for your specific model year and wheel type for the precise torque values.
• Torque Pattern: A star pattern or criss-cross pattern should be used when tightening lug nuts. This ensures even clamping force across the wheel hub and prevents warping of the wheel or rotor. Tighten in stages, bringing all nuts to about half torque, then three-quarters, and finally the full specified torque.

Common Tire Issues for this Vehicle

Given the demanding nature of commercial truck operations, the International MV can experience several common tire issues if not properly maintained:

• Uneven Wear: Often caused by improper inflation pressure (under or over), misaligned axles, worn suspension components, or aggressive driving. Cupping, feathering, and shoulder wear are common patterns.
• Underinflation: Leads to excessive heat buildup, reduced fuel economy, accelerated shoulder wear, and an increased risk of tire failure. This is arguably the most common and damaging tire issue for commercial vehicles.
• Overinflation: While less common than underinflation, it can lead to a harsh ride, reduced traction, and accelerated wear in the center of the tread.
• Sidewall Damage: Potholes, curbs, and road debris can cause cuts, punctures, or bulges in the tire sidewall, necessitating immediate replacement.
• Tread Separation: Can occur due to manufacturing defects, severe impacts, or prolonged underinflation leading to excessive heat. This is a dangerous failure that requires immediate attention.
• Vibrations: Can indicate an unbalanced tire, bent wheel, or other suspension issues. Prompt diagnosis is important to prevent further wear and ensure safe operation.

Regular inspections, proper inflation, and timely rotation (if applicable to the tire type and application) are key to maximizing tire life and ensuring safe operation of your International MV.
