2018 Ford F150 Largest Tires Fit With Leveling Kit & 16in Wheels

For your 2018 Ford F-150 with stock 16” wheels and a leveling kit, the largest tires you can realistically fit are around LT285/70R17 or LT275/65R18 size range, but since you have 16” wheels, you’ll be limited to tires that fit that rim diameter.

That means the biggest tires on your stock 16” wheels with a leveling kit are roughly LT285/75R16 or LT275/70R16. These tires will give you a bit more height and width without requiring major trimming or suspension modifications.

Top recommendations for largest tires with leveling kit & stock 16” wheels

1. LT285/75R16 All-Terrain Tires

   • Max size for 16” wheels with minimal rubbing on a 2-3” leveling kit
   • Cost: $200-$300 per tire
   • Install difficulty: DIY-friendly (mounting/balancing required)

2. LT275/70R16 Mud-Terrain or All-Terrain Tires

   • Slightly narrower but taller option, good for off-road grip
   • Cost: $180-$280 per tire
   • Install difficulty: DIY-friendly

3. 2-3 Inch Leveling Kit (if not already installed)

   • Provides enough lift to clear larger tires without suspension overhaul
   • Cost: $150-$300
   • Install difficulty: Moderate (some mechanical skill required)

Compatibility & prerequisites

• Confirm your F-150’s exact trim and suspension setup (e.g., 4x4 or 4x2, stock shocks)
• Stock 16” wheels typically are 7-8” wide; verify wheel width and offset for tire fitment
• Leveling kit height: 2-3” max to avoid suspension geometry issues and rubbing
• Check for rubbing on inner fender liners and control arms at full lock and suspension compression
• No major trimming or aftermarket fender flares typically needed with these sizes
• Speedometer recalibration recommended after tire size increase
• Larger tires may affect ABS and traction control calibration

Realistic expectations & tradeoffs

• Gains: Better ground clearance, more aggressive look, improved off-road traction
• Tradeoffs: Slightly reduced fuel economy, possible speedometer inaccuracy, minor impact on ride comfort
• Stock wheels may limit tire choice and availability compared to aftermarket wheels
• Larger tires increase unsprung weight, potentially affecting handling and braking
• No major driveline modifications needed if you stay within these sizes

If you want to go bigger than LT285/75R16 on stock 16” wheels, you’ll likely need aftermarket wheels with wider widths and different offsets, plus possible trimming or suspension upgrades.
