How to confirm your exact tire size
To determine the precise tire size for your Ford F-250, use these steps. This helps if you own a used truck or a modified one where sizes may differ from stock.
- Check the driver-side door jamb placard for the tire size information, listed alongside recommended inflation pressures.
- Consult the owner's manual or the window sticker (if applicable) for the original equipment tire size.
- Read the tire sidewall, where the size is printed (for example, P265/70R17 or C275/65R18).
- If you have aftermarket tires, compare your current tires’ size markings to the stock data or consult your seller/dealer for compatibility and load ratings.
If you’re planning tire replacements or a wheel upgrade, ensure the new size maintains proper load rating and clearance. When in doubt, a Ford dealer or tire professional can confirm compatibility with your specific F-250 configuration.
Summary
The Ford F-250 does not have a universal tire size; it depends on year, trim, and wheel package. Typical factory sizes include 265/70R17, 275/65R18, and 275/60R20. To know the exact size for your truck, consult the door placard, the owner's manual, or the tire sidewall markings, and verify with a dealer or tire specialist if you’re considering replacements or upgrades.

Is a 285 tire the same as a 33?
No, a 285 tire is not the same as a 33-inch tire because the numbers represent different dimensions: 285 refers to the tire's width in millimeters, while 33 inches typically refers to the overall height. However, a specific tire size like a 285/70R17 is close in height to a 33-inch tire, with an approximate overall diameter of 32.7 inches.
Tire sizing explained
- 285: This number in a metric tire size (like 285/70R17) is the tire's width across the tread in millimeters.
- 33: In common off-road tire terminology, "33" refers to the tire's approximate overall height in inches.
- The middle number: The number in the middle of the metric size (e.g., 70 in 285/70R17) is the aspect ratio—the height of the tire's sidewall as a percentage of its width.
- Putting it together: To find the overall diameter, you calculate the sidewall height (width multiplied by aspect ratio) and add it twice, then add the wheel diameter.
- For a 285/70R17:
- Width: 285 mm≈11.22 inches285 mm is approximately equal to 11.22 inches285 mm≈11.22 inches
- Sidewall height: 11.22 inches×0.70≈7.85 inches11.22 inches cross 0.70 is approximately equal to 7.85 inches11.22 inches×0.70≈7.85 inches
- Total height: (7.85 inches×2)+17 inch wheel≈32.7 inchesopen paren 7.85 inches cross 2 close paren plus 17 inch wheel is approximately equal to 32.7 inches(7.85 inches×2)+17 inch wheel≈32.7 inches
