2023 International LT — Tire Size & Pressure

Quick answer

• OEM Tire Size: Varies by configuration, commonly 11R22.5 or 295/75R22.5
• Recommended Cold Tire Pressure: Varies by load and tire type, refer to door placard.
• Bolt Pattern: 10-lug on 285.75mm (10x285.75)
• Wheel Size: 22.5 x 8.25 inches
• Load Index/Speed Rating: Varies significantly based on tire selection and intended use. Typically J (62 mph) for steer and drive tires.
• Spare Tire Size: Often not equipped with a spare; repair kits or roadside assistance are common. If equipped, it would match one of the OEM sizes.
• TPMS Frequency: 315 MHz or 433 MHz depending on the specific TPMS system installed.

Tire sizes by trim

The International LT series is a highly customizable heavy-duty truck, and as such, tire sizes are not tied to specific "trims" in the same way they are for passenger vehicles. Instead, tire sizes are specified based on the intended application, gross vehicle weight rating (GVWR), and axle configurations. Common OEM tire sizes include:

Axle Position	Common Tire Sizes (Dual Rear Configuration)
Steer	11R22.5, 295/75R22.5
Drive	11R22.5, 295/75R22.5

Other less common but available sizes may include low-profile options or wider tires for specific hauling needs.

Recommended replacement tires

When replacing tires on a 2023 International LT, it's crucial to select tires that match or exceed the original equipment specifications for load capacity and speed rating. Given the diverse applications of the LT series, tire choices will vary significantly. Here are some popular and reliable options in different price tiers, assuming a common 11R22.5 size:

• Premium Option (Long Haul Steer): Michelin X Line Energy Z

  • Why: Excellent fuel efficiency, long tread life, and reliable handling. Designed for line-haul applications.
  • Price Tier: $$$$

• Mid-Range Option (All-Position): Goodyear Marathon RSA

  • Why: A versatile all-position tire offering good traction and durability for regional and urban applications.
  • Price Tier: $$$

• Value Option (Drive Axle): Bridgestone M700 Ecopia

  • Why: Strong traction in various conditions and good fuel economy for a drive tire. A cost-effective choice for many operations.
  • Price Tier: $$

When selecting tires, always consult with a commercial tire specialist who can help you choose the correct tires for your specific vehicle configuration and operational needs.

When to inflate to max load psi

For heavy-duty trucks like the International LT, proper tire inflation is paramount for safety, fuel efficiency, and tire longevity. Unlike passenger cars where a single recommended pressure is common, truck tire pressures are highly dependent on the actual load being carried.

While your door placard will provide a recommended cold tire inflation pressure, this is often a starting point. It's generally recommended to inflate your tires to the maximum load psi only when you are consistently operating at or near the maximum Gross Vehicle Weight Rating (GVWR) or Gross Axle Weight Rating (GAWR). Over-inflating for lighter loads can lead to a harsher ride, uneven tire wear (center wear), and reduced traction. Under-inflating, conversely, can cause excessive heat buildup, reduced fuel economy, and premature tire failure.

Always use a reliable tire pressure gauge and check tire pressures when the tires are cold. Many fleets utilize tire pressure monitoring systems (TPMS) as a supplementary tool, but manual checks remain essential. Consult your tire manufacturer's load and inflation tables for precise recommendations based on your specific tire size and actual axle weights.

Lug nut torque & pattern

Proper lug nut torque is critical for safe wheel retention on heavy-duty trucks. The 2023 International LT typically uses a 10-lug wheel pattern.

• Lug Nut Torque: Refer to your owner's manual for the exact specification, but a common range for commercial truck wheels with 22.5-inch wheels is 450–500 ft-lbs (610–678 Nm).
• Tightening Pattern: Always follow a star or criss-cross pattern to ensure even clamping force across the wheel hub. This prevents wheel distortion and helps secure the wheel properly.

It's recommended to re-check lug nut torque after the first 50-100 miles of operation after any wheel removal or installation, and then at regular maintenance intervals.

Common tire issues for this vehicle

Heavy-duty trucks like the International LT are subjected to demanding conditions, leading to specific tire wear patterns and issues. Awareness of these can help with preventative maintenance:

• Irregular Wear: Due to the heavy loads and diverse road conditions, irregular wear patterns like feathering, cupping, or shoulder wear are common. These can often be traced back to improper inflation, misalignment, worn suspension components, or aggressive driving habits.
• Heat Buildup: Prolonged high speeds, heavy loads, and especially underinflation can lead to excessive heat buildup in tires, significantly increasing the risk of tire failure (blowouts).
• Punctures and Road Hazards: Commercial trucks are frequently on routes where road debris is common, increasing the likelihood of punctures. Regular inspections for foreign objects are crucial.
• Cracking and Weathering: Over time, exposure to UV light and environmental factors can cause sidewall cracking. Proper tire storage (if applicable) and timely replacement are important.

Regular pre-trip and post-trip inspections, maintaining correct tire pressures, and ensuring proper wheel alignment are the best defenses against these common tire issues.
