• Recommended Cold Tire Pressure: Varies by configuration and load, refer to vehicle-specific door placard. (Typically 85-110 PSI for most applications)
• Bolt Pattern: Varies by axle and wheel type, common large truck patterns (e.g., 10-hole on 285.75mm bolt circle)
• Wheel Size: Varies by configuration (e.g., 22.5x8.25)
• Load Index/Speed Rating: Varies significantly by tire size and application (e.g., G/H/J for load range, L/M/N for speed rating)
• Spare Tire Size: Typically matches one of the vehicle's OEM tire sizes
• TPMS Frequency: 433 MHz (for systems equipped)

Tire sizes by trim

The International MV is a medium-duty commercial truck chassis with a vast array of configurations, powertrains, and vocational applications. This means that tire sizes, wheel types, and pressure recommendations are highly dependent on the "trim" or, more accurately, the specific build sheet for your truck. Consult your vehicle's door placard and owner's manual for the most accurate information.

Here are common tire sizes you might find on a 2018 International MV, but this is not exhaustive:

Recommended replacement tires

Choosing replacement tires for an International MV requires careful consideration of the truck's typical use, load, and desired performance characteristics such as fuel economy, tread life, and traction. Since the MV is a commercial vehicle, tire choices are often dictated by fleet managers and specific application needs. Always replace tires with those that meet or exceed the original equipment's load index and speed rating.

Here are some popular and highly-regarded commercial truck tire options that might be suitable for various International MV applications. Prices can vary widely based on dealer, bulk purchasing, and specific tire features. Always choose tires that match your truck's installed wheel size.

• Michelin X Line Energy Z/D/T (Steer/Drive/Trailer): A premium choice known for excellent fuel efficiency and long tread life. Often seen in regional and line-haul applications. Price Tier: Premium
• Goodyear Fuel Max Series (Steer/Drive): Another strong contender for fuel efficiency and durability, offering good all-around performance for highway and regional use. Price Tier: Premium
• Bridgestone M773/R283A (Drive/Steer): Robust and reliable tires suitable for a variety of applications, including some vocational uses due to their durability and traction properties. Price Tier: Premium/Mid-Range
• Continental Hybrid HS3/HD3 (Steer/Drive): Designed for a balance of fuel efficiency, traction, and tread life, making them versatile for regional and urban delivery. Price Tier: Mid-Range
• Hankook AH12/DH12 (Steer/Drive): A more economical option that still offers solid performance and good wear characteristics for many medium-duty applications. Price Tier: Economy/Mid-Range

When to inflate to max load psi

For heavy-duty and medium-duty trucks like the International MV, it is common and often necessary to inflate tires to the maximum cold inflation pressure indicated on the tire's sidewall. This is especially true when the vehicle is operating near its Gross Vehicle Weight Rating (GVWR) or Gross Axle Weight Rating (GAWR).

• Always refer to your vehicle-specific door placard FIRST. The placard provides the recommended cold tire inflation pressure for your specific truck configuration and axle loads. Use this as your primary guide.
• Maximum Load Conditions: When regularly hauling heavy loads that push the limits of your truck's payload capacity, inflating to the maximum PSI on the tire sidewall ensures the tire can carry its rated load without excessive heat buildup, premature wear, or structural fatigue. Under-inflating when heavily loaded can lead to tire failure.
• Empty vs. Loaded: Some fleets adjust tire pressure based on whether the truck is empty or loaded. However, for most commercial operations, maintaining the placard-recommended pressure or tire sidewall max pressure for loaded conditions is standard practice to ensure safety and tire longevity.
• Consult a Professional: If you are unsure about the correct tire pressure for your specific application, consult with a tire professional or your International dealer.

Lug nut torque & pattern

The lug nut torque and pattern are critical for the safe operation of an International MV. Due to the wide variety of axle and wheel configurations, exact specifications can differ. Always refer to your truck's owner's manual or service manual for the precise torque values.

• Bolt Pattern: Most medium and heavy-duty trucks utilize a hub-piloted wheel system with 10 lug nuts. Common bolt circles include 285.75mm (11.25 inches).
• Lug Nut Torque: For 10-hole hub-piloted wheels on medium-duty trucks, common lug nut torque specifications are in the range of 450-500 ft-lbs (610-678 Nm). Verify this with your vehicle's specific documentation.
• Tightening Pattern: Always tighten lug nuts in a star or crisscross pattern to ensure even clamping force across the wheel hub. After initial tightening, it is crucial to re-torque the lug nuts after the first 50-100 miles of operation and periodically thereafter, especially after any wheel removal or tire service.

Common tire issues for this vehicle

Commercial trucks like the International MV are subject to significant stress, and their tires are critical to their operation. Common tire issues often stem from improper maintenance, overloading, or application-specific wear patterns.

• Uneven Wear: Often caused by improper tire pressure (under or over-inflation), misaligned axles (toe, camber, caster issues), worn steering/suspension components, or imbalances. Regular inspections and proper maintenance can mitigate this.
• Rapid Wear: Can be a result of aggressive driving, overloading, improper tire selection for the application, or severe misalignments.
• Punctures and Sidewall Damage: Common in vocational applications due to debris, curbs, and rough terrain. Regular pre-trip inspections are vital.
• Heat Buildup and Blowouts: Primarily caused by chronic under-inflation, overloading, or damaged tires. Maintaining correct tire pressure and performing regular tire inspections are the best preventative measures.
• Tire Cupping/Scalloping: Potholes can cause damage to tires and suspension. Often indicates an issue with suspension components (shocks, bushings) or tire balance.
