The 2003 Ford F-250 has a bolt pattern, also referred to as a lug pattern, of 8x170, or read aloud, 8 on 170. Here’s what that represents:

So, that’s one less wheel spec mystery solved! But if you’re swapping out your current wheels for a new set, you’ll also want to know some additional specifications to find an option that’s the proper fit:
  • Factory wheel size: 16” to 18” 
  • Lug size: M14 x 2
  • Offset: -10 to 15 mm
  • Center bore: 124.9 mm
Keep in mind that based on your 2003 Ford F-250’s configurations, it’s possible your own wheel specs might differ from the ones shown here. Luckily, most wheel and tire shops will have tools that let you check whether a particular option will be compatible with your truck.

How to measure your Ford F-250’s bolt pattern

If you want to double-check your 2003 Ford F-250’s bolt pattern yourself, it’s pretty easy to do so. All you’ll need for the job is a measuring tape.
Since each wheel on the F-250 has eight bolts, measuring your lug pattern is pretty straightforward. Start from the center of any bolt hole and measure to the center of the bolt hole directly across from it.
This measurement will give you your pitch circle diameter. Once you have that, place it after the number of bolts (eight), and there’s your bolt pattern!
