• Spare Tire Size: Matches one of the OEM tire sizes (e.g., 275/65R18)
• TPMS Frequency: 315 MHz

Tire sizes by trim

Note: Some trims may have had optional larger wheel and tire packages from the factory. Always verify your specific vehicle's door placard for exact OEM tire size and recommended pressures.

Recommended replacement tires

When it's time for new tires on your 2020 Ford F-250 Super Duty, selecting tires that can handle the demands of a heavy-duty truck is crucial. You'll want tires with a high load range (typically Load Range E or 10-ply equivalent) to ensure proper towing and hauling capacity.

Here are a few popular options:

• Michelin Defender LTX M/S (Premium Tier): A top-rated all-season light truck tire known for its long tread life, excellent wet and dry traction, and quiet ride. Great for daily driving, towing, and light off-roading.
• BFGoodrich All-Terrain T/A KO2 (Premium Tier): An iconic all-terrain tire that offers exceptional off-road capability without sacrificing too much on-road comfort. Excellent for those who frequently venture off paved roads or deal with challenging weather conditions.
• Firestone Transforce AT2 (Mid-Range Tier): A durable all-terrain tire designed for demanding work applications. It provides good traction in various conditions and is built to withstand heavy loads.
• Goodyear Wrangler Duratrac (Premium Tier): A popular aggressive all-terrain tire that performs well in snow, mud, and on rocky terrain. It's a good choice for those needing more off-road prowess than a standard all-season tire.

When to inflate to max load psi

For heavy-duty trucks like the Ford F-250, tire pressure recommendations from the factory door placard are usually for an unloaded or lightly loaded vehicle. However, when you're towing heavy trailers or hauling significant payloads, you should increase your rear tire pressure to the maximum cold inflation pressure listed on the tire's sidewall. This is often 80 PSI for Load Range E tires. The front tires may also require a slight increase depending on the weight distribution.

Why is this important? Running underinflated tires with heavy loads can lead to several problems:

• Reduced Stability: The tires can flex excessively, making the truck feel "squirrely" and harder to control, especially at highway speeds.
• Increased Heat Buildup: Excessive flexing generates heat, which can lead to premature tire wear or even catastrophic tire failure.
• Decreased Fuel Economy: Soft tires increase rolling resistance.
• Uneven Tire Wear: Underinflation can cause the shoulders of the tire to wear out faster.

Always consult your truck's owner's manual for specific guidelines on adjusting tire pressure for loaded conditions. The door placard pressure is a minimum for safety and ride quality with typical loads, but heavy towing and hauling require higher pressures for optimal performance and safety.

Lug nut torque & pattern

• Lug Nut Torque: 165 lb-ft (pound-feet)
• Bolt Pattern: 8x170mm (meaning 8 lug nuts on a 170mm bolt circle diameter)

When tightening lug nuts, always use a torque wrench to ensure they are properly secured. Tighten them in a star or criss-cross pattern to ensure even seating of the wheel against the hub. Incorrect or uneven torque can lead to wheel warping, vibrations, or even wheels coming loose.

Common tire issues for this vehicle

Owners of 2020 Ford F-250 Super Duty trucks may experience a few common tire-related issues, often related to the truck's heavy-duty nature:

• Rapid or Uneven Tread Wear: This can be due to aggressive driving, improper tire pressure (especially when towing/hauling), or misalignment. Regularly rotating tires (every 5,000-7,500 miles) and maintaining proper inflation will help mitigate this.
• Cupping or Feathering: Often a sign of worn suspension components (shocks, ball joints) or an alignment issue. These wear patterns can lead to vibrations and increased road noise.
• TPMS Sensor Malfunctions: While generally reliable, TPMS sensors can occasionally fail or lose connection, especially after tire rotations or replacements. This typically triggers a warning light on the dashboard.
• Hydroplaning: With wider tires, especially those with worn tread, the F-250 can be susceptible to hydroplaning in heavy rain if driven too fast. Ensure your tires have adequate tread depth and reduce speed in wet conditions.

Regular tire inspections, rotations, and maintaining correct tire pressure are key to maximizing tire life and ensuring safe operation of your F-250 Super Duty.
