Critical Rubbing Points & How to Fix Them
Specific areas where oversized tires rub on the Ford F-150 and proven solutions.
Front & Rear Crash Bars (2015+)
Ford installed structural high-strength steel crash bars in front and behind the front wheels. When installing 35-inch tires on negative offset wheels, the tire lugs will smack these bars at partial turn.
Front Lower Air Dam / Bumper Valance
The flexible black plastic air dam hanging below the front bumper contacts the outer tread blocks of 33.5"+ tires when backing up with steering turned.
Upper Control Arm (UCA) Ball Joint Cup
Factory stamped steel UCAs sit very close to wide tires (12.50" wide) on factory +44mm high-offset wheels.
Wheel Offset & Backspacing Advice
Why offset matters as much as tire diameter.
The sweet spot for leveled F-150s is +18mm to +20mm offset on a 9-inch wide wheel. Running 0mm or negative offset (-12mm / -24mm) pushes the tire outward directly into the crash bars.
Frequently Asked Questions: Ford F-150 Tire Fitment
What is the biggest tire you can fit on a stock Ford F-150 without a lift?▼
The biggest tire you can safely fit on a stock 2015-2024 Ford F-150 without any rubbing or trimming is a 33.2-inch tire, specifically 275/70R18 on 18-inch wheels, or 275/60R20 on 20-inch wheels.
Can you fit 35-inch tires on an F-150 with just a leveling kit?▼
Yes, you can fit 35-inch tires with a 2.0-inch or 2.5-inch leveling kit, but offset is critical. A narrow 35 (like 35x11.50R20 or 295/60R20) on factory +44mm wheels will clear with zero rubbing. A wide 35x12.50 on aftermarket negative offset wheels will rub the front crash bars.
Do I have to remove the crash bars for 35s?▼
No, you do not have to cut them out. Cutting crash bars can compromise passenger crash test safety and insurance coverage. Most owners use a hydraulic porta-power spreader to push the bars 0.5 to 1.0 inch outward, providing plenty of clearance.
