Tire Sizes by Trim

Recommended Replacement Tires

When replacing tires on your 2015 Ford F-150, it's important to choose tires that meet or exceed the original equipment specifications for load capacity, speed rating, and overall performance. Here are some popular options across different price tiers:

• Mid-Range All-Terrain: BFGoodrich All-Terrain T/A KO2 (Price Tier: $$$) - An industry standard for off-road capability combined with decent on-road manners and excellent durability. Great for trucks that see a mix of highway and dirt roads.
• Premium Highway All-Season: Michelin Defender LTX M/S (Price Tier: $$$) - Known for its long tread life, quiet ride, and excellent wet and dry traction. An ideal choice for F-150 owners who prioritize comfort and longevity on paved roads.
• Value All-Season: Cooper Discoverer HTP (Price Tier: $$) - Offers a good balance of performance, durability, and affordability. A solid choice for everyday driving and light-duty hauling.
• Aggressive All-Terrain/Mud-Terrain: Nitto Ridge Grappler (Price Tier: $$$) - For those seeking a more aggressive look and enhanced off-road performance without sacrificing too much on-road comfort. Excellent for challenging conditions.

When to Inflate to Max Load PSI

For 2015 Ford F-150 trucks equipped with LT-Metric (Light Truck) tires, the recommended cold tire pressure listed on your door placard will often specify a range or a different pressure for front and rear, especially when carrying heavy loads. The "max load PSI" (often found on the tire's sidewall) refers to the maximum pressure the tire can hold to support its maximum rated load. You should only inflate to max load PSI when:

• Towing the maximum rated trailer weight.
• Hauling the maximum rated payload in the bed.
• Operating under extreme heavy-duty conditions where the vehicle is consistently at or near its Gross Vehicle Weight Rating (GVWR) or Gross Axle Weight Rating (GAWR).

For everyday driving unloaded or with light loads, always adhere to the pressure recommended on your F-150's door placard. Over-inflating can lead to a harsh ride, reduced traction, uneven tire wear, and potentially premature tire failure. Under-inflating can cause excessive heat buildup, poor handling, and also lead to premature tire failure.

Lug Nut Torque & Pattern

The lug nuts on your 2015 Ford F-150 should be torqued to 150 ft-lbs (204 Nm).

Always tighten lug nuts in a star or criss-cross pattern to ensure even seating of the wheel against the hub. This helps prevent warping of the brake rotors and ensures the wheel is securely fastened. After driving approximately 50-100 miles after a wheel removal/installation, it
