Tire Sizes by Trim

Recommended Replacement Tires

When it's time for new tires on your 2016 F-350 Super Duty, selecting the right set is crucial for maintaining its towing and hauling capabilities, as well as ensuring a safe and comfortable ride. Here are a few popular options that cater to different needs and budgets:

• Michelin LTX A/T2 ($$$): A premium all-terrain tire known for its excellent tread life, quiet ride, and strong performance in various conditions, including light off-road use and towing. It offers a great balance of comfort and capability.
• BFGoodrich All-Terrain T/A KO2 ($$$): A legendary all-terrain tire favored by many truck owners for its aggressive tread pattern, exceptional off-road traction, and remarkable durability. It's a solid choice for those who frequently venture off paved roads or demand maximum grip in challenging environments.
• Goodyear Wrangler DuraTrac ($$): A popular hybrid all-terrain/mud-terrain tire that provides aggressive traction for off-road adventures while still maintaining reasonable on-road manners. It's a good option if you need more aggressive off-road capability than a typical all-terrain but still want a tire that performs well on pavement.
• Firestone Transforce AT2 ($$): A durable all-season, all-terrain light truck tire designed for commercial and heavy-duty applications. It offers good traction and stability for hauling and towing, making it a reliable choice for work trucks.

When to Inflate to Max Load PSI

For heavy-duty trucks like the 2016 Ford F-350 Super Duty, understanding tire pressure beyond the door placard recommendations is essential, especially when hauling or towing near your vehicle's maximum capacities. The pressures listed on your door placard are general guidelines for typical passenger car use and light hauling scenarios.

However, when you are carrying a heavy load or towing a substantial trailer, you should inflate your tires to the maximum cold inflation pressure listed on the tire's sidewall. This pressure, often significantly higher than the door placard recommendation, is the pressure required to support the tire's maximum rated load. Inflating to this pressure when fully loaded prevents excessive tire flexing, which can lead to heat buildup, premature wear, and even tire failure. Always consult the specific tire's sidewall for its maximum cold inflation pressure, and adjust accordingly before starting your journey with a heavy load. Remember to reduce the pressure back to the door placard recommendation when running unloaded to ensure optimal ride quality and even wear.

Lug Nut Torque & Pattern

Proper lug nut torque is critical for safe wheel retention. For the 2016 Ford F-350 Super Duty, the recommended lug nut torque is 165 ft-lbs (224 Nm). Always use a torque wrench to ensure accurate tightening. The tightening pattern is just as important as the torque itself to ensure the wheel is seated evenly against the hub. Always tighten the lug nuts in a star or crisscross pattern to gradually bring the wheel flush against the hub. Never tighten them in a circular pattern, as this can lead to uneven seating and potential complications.

Common Tire Issues for This Vehicle

Owners of 2016 Ford F-350 Super Duty trucks may occasionally encounter specific tire-related issues, often tied to their heavy-duty nature and usage:

• Uneven Tire Wear: This can be a common issue, especially on the front tires, due to the weight of the diesel engine and the demands of heavy steering. Misalignment, worn suspension components, or improper tire rotation schedules can exacerbate this. Regularly rotating your tires (every 5,000-7,500 miles) and having your alignment checked can help mitigate this.
• TPMS Sensor Issues: While generally reliable, TPMS (Tire Pressure Monitoring System) sensors can occasionally fail or give inaccurate readings. This could be due to battery failure within the sensor (they typically last 5-10 years), damage during tire changes, or interference. If you have a persistent TPMS warning, have the system diagnosed by a professional.
• Tire Cupping/Scalloping: This refers to an uneven wear pattern characterized by alternating high and low spots around the circumference of the tire. It’s often a sign of worn shock absorbers, unbalanced tires, or worn suspension components. Addressing these underlying issues is crucial to prevent further tire damage and maintain ride quality.
• Hydroplaning (with worn tires): With the large contact patch of many F-350 tires, as tread depth wears down, the risk of hydroplaning in wet conditions increases. This is particularly noticeable with aggressive-tread all-terrain tires once the siping (small slits in the tread blocks) wears away. Regular inspection of tread depth and replacing worn tires is essential for safety.
