Tire Sizes by Trim

The 2024 Ford F-350 Super Duty offers various tire sizes depending on the trim level and optional packages. Always check your vehicle's doorjamb placard for the definitive OEM tire size for your specific truck.

Recommended Replacement Tires

When replacing tires on your 2024 Ford F-350 Super Duty, it's crucial to select tires that meet or exceed the original equipment's load carrying capacity (E-rated or higher) and speed rating. Given the F-350's heavy-duty nature, here are 3-5 popular and highly-regarded replacement tire options, catering to different needs and budgets:

• Michelin Defender LTX M/S: (Premium Tier) Known for excellent all-season traction, long tread life, and a quiet, comfortable ride. A popular choice for those who prioritize highway commuting and light-duty towing.
• BFGoodrich All-Terrain T/A KO2: (Mid-Premium Tier) An industry standard for all-terrain performance. Offers exceptional traction in dirt, mud, and snow, combined with good on-road manners and durability. Ideal for F-350 owners who venture off Pavement or require robust towing tires.
• Goodyear Wrangler Duratrac: (Mid-Premium Tier) Aggressive all-terrain tire with good off-road capability and respectable on-road performance. Features a severe snow service rating, making it a strong contender for colder climates.
• Toyo Open Country A/T III: (Mid-Tier) A versatile all-terrain tire offering a balance of off-road traction, on-road comfort, and wet weather performance. A great option for those seeking a durable and capable all-around tire.

When to Inflate to Max Load PSI

For heavy-duty trucks like the Ford F-350 Super Duty, understanding when to adjust tire pressure is critical for safety and tire longevity. Your door placard will list the recommended cold tire pressures for various loading conditions.

Always refer to your door placard for specific max load inflation pressures. However, generally, you should inflate your tires to the maximum load PSI only when your truck is carrying or towing its maximum rated capacity. This ensures the tires can safely support the load and prevents excessive heat buildup, which can lead to tire failure. When the truck is unloaded or lightly loaded, running at maximum PSI can lead to a harsher ride, uneven tire wear (center wear), and potentially reduced traction due to a smaller contact patch.

Lug Nut Torque & Pattern

The lug nut torque for your 2024 Ford F-350 Super Duty is critical for proper wheel retention and safety.

• Lug Nut Torque: 165 ft-lbs (224 Nm). Always use a calibrated torque wrench and tighten in stages.
• Bolt Pattern: 8x170mm. This means there are 8 lug nuts on a bolt circle diameter of 170mm.
• Tightening Pattern: Always tighten lug nuts in a star or crisscross pattern to ensure even seating of the wheel against the hub. This helps prevent wheel distortion and wobble.

Common Tire Issues for this Vehicle

While the F-350 Super Duty is a robust vehicle, like any heavy-duty truck, it can experience certain tire-related issues if not properly maintained:

• Uneven Tire Wear: This is often the most common issue. Due to the diverse loads an F-350 can carry, improper tire pressure for the current load is a leading cause. Underinflation can cause wear on the outer edges, while overinflation (especially when unloaded) can cause wear in the center of the tread. Misalignment or worn suspension components can also contribute.
• Rapid Tire Wear: Given the torque and weight of the F-350, aggressive driving, frequent heavy hauling, or towing without proper tire inflation can accelerate tire wear. Choosing tires with a lower load rating than OEM can also contribute.
• Hydroplaning: With wider tires and the potential for heavy loads, ensuring adequate tread depth is vital to prevent hydroplaning in wet conditions. Worn tires are significantly more susceptible.
• Blowouts: While rare with proper maintenance, blowouts can occur due to road hazards, overloading, or running severely underinflated tires, especially under heavy loads. Always check for cuts, bulges, or punctures regularly.
• TPMS Malfunctions: Temperature fluctuations, sensor battery life, or physical damage can sometimes cause the Tire Pressure Monitoring System (TPMS) to give false readings or malfunction. If your TPMS light illuminates, always manually check your tire pressures.

Regular tire rotations (every 5,000-7,500 miles), balancing, and alignments are highly recommended to maximize tire life and ensure safe operation of your F-350 Super Duty.
