The F150 Wheel Fitment Bible: Offsets, Backspacing, and Rubbing Explained
Share
The 2021–2025 Ford F-150 is a handsome truck, but the factory wheels—especially on the lower trims—often look too polite. They sit tucked far inside the fenders, giving the truck a narrow, top-heavy look.
You want a wider stance. You want aftermarket wheels.
But then you see the numbers: Offset -12mm. Backspacing 4.75". Bore 87.1mm.
If you buy the wrong combination, your tires will rub the high-strength steel "Crash Bars" located in your wheel wells, forcing you to cut up your brand new truck.
In this guide, we demystify the math. We explain the difference between Positive Offset (Tucked) and Negative Offset (Deep Dish), and tell you exactly which size you need to run 33s or 35s without rubbing.

Frequently Asked Questions (Wheels)
Will 33s fit on stock wheels?
Yes. You can typically fit a 33-inch tire (e.g., 275/70R18 or 285/70R17) on a stock 2021+ F-150 without rubbing, provided you use the factory wheels. If you switch to aftermarket wheels with an aggressive offset (0mm or negative), those same tires might rub the crash bars.
What offset do I need to stick out just a little?
Target an offset between +12mm and +1mm.
- Stock is usually +44mm (tucked in).
- +18mm brings the tire flush with the fender.
- 0mm pokes the tire out about 0.5-1.0 inch past the fender.
Do I need new TPMS sensors?
Yes (Recommended). While you can swap your old sensors over, they often break during removal, and the batteries die after 5-7 years. We recommend buying a new set of 315MHz TPMS sensors (Ford spec) with your new wheels so you don't have a dash light on.
