What width tires come on a Ford F350?
There isn’t a single universal width for every Ford F-350. The tire width varies by model year, trim level, and wheel package. In recent F-350s, stock tires typically fall in a range from about 9.6 to 11 inches wide (roughly 245–275 millimeters) depending on the wheel size (17–20 inches).
The exact width for your truck is printed on the tire placard inside the door jamb and also listed in the vehicle’s owner documentation. If you’re replacing tires, it’s best to match the OEM size specified for your specific configuration or consult Ford’s guidance for your payload and drivetrain setup.
Understanding tire size notation
Tire sizes follow a standard format such as P245/75R17. Here’s how to read it: the first number (245) is the section width in millimeters; the second number (75) is the aspect ratio, which is the height as a percentage of the width; the “R” indicates radial construction; the final number (17) is the wheel diameter in inches. So a 245/75R17 tire is 245 mm wide and fits a 17-inch wheel, with a sidewall height equal to 75% of 245 mm.
Common stock wheel sizes for current Ford F-350
Ford uses several wheel sizes on the F-350 depending on trim and options. The following list outlines typical stock configurations and their approximate tire widths corresponding to common wheel sizes.
- 17-inch wheels — typically around 245/75R17 or 265/70R17 (section width about 245–265 mm; roughly 9.6–10.4 inches)
- 18-inch wheels — typically around 275/65R18 or 275/70R18 (section width 275 mm; about 10.8 inches)
- 20-inch wheels — typically around 275/60R20 or 275/65R20 (section width 275 mm; about 10.8 inches)
These widths represent common OEM configurations for many 2020s-era F-350 models. Exact width can vary by payload package, drivetrain, and optional wheel choices. Always verify your specific build to ensure proper fitment and performance.
How to verify your exact tire width on your F-350
To confirm the precise width for your vehicle, use these steps:
- Check the door jamb placard on the driver’s side for the recommended tire size, including width, aspect ratio, and wheel diameter.
- Look at the tire sidewall of the currently installed tires—the first number indicates the width in millimeters (e.g., 245, 275).
- Consult your owner’s manual or the Ford Build/Window sticker for your specific trim and wheel package.
- If in doubt, contact a Ford dealer or a tire professional with your VIN to confirm the OEM size for your exact configuration.
Knowing the exact specification ensures you select compatible tires, maintain correct clearance, and preserve load ratings and handling characteristics.
Summary
The Ford F-350 does not have a single tire width. Width depends on the model year, trim level, and wheel package, with common OEM sizes ranging from about 245 mm to 275 mm (approximately 9.6 to 11 inches) in section width, across 17–20 inch wheels. Always verify the exact size from the door placard, owner’s manual, or Ford’s official spec sheets for your specific truck, especially if you’re replacing tires or changing wheel sizes.
Are 285 tires equal to 33?
No, a "285" tire is not the same as a "33," but some 285 tires are approximately 33 inches tall. The number "285" refers to the tire's width in millimeters, while "33" refers to the overall diameter in inches. To determine the exact diameter of a "285" tire, you must also know the tire's aspect ratio and rim diameter. For example, a 285/70R17 tire has an approximate diameter of 32.7 inches, which is often rounded up to 33 inches.
Tire size explained
- "285": This is the width of the tire in millimeters. A 285mm tire is approximately 11.22 inches wide.
- "33": This is the overall diameter of the tire in inches. It is a "floatation" size, commonly used for off-road or truck tires.
- The "middle number" (e.g., 70 in 285/70R17): This is the aspect ratio, which is the height of the tire's sidewall as a percentage of its width. For example, in a 285/70R17, the sidewall is 70% of 285mm.
- "R17": This is the rim diameter in inches. "R" stands for radial, and "17" is the size of the wheel the tire fits.
Example calculation
To calculate the approximate diameter of a 285/70R17 tire:
- Calculate the sidewall height: 285mm×0.70=199.5mm285 mm cross 0.70 equals 199.5 mm285mm×0.70=199.5mm.
- Convert the sidewall height to inches: 199.5mm/25.4≈7.85 inches199.5 mm / 25.4 is approximately equal to 7.85 inches199.5mm/25.4≈7.85 inches.
- Double the sidewall height to account for the top and bottom: 7.85×2=15.7 inches7.85 cross 2 equals 15.7 inches7.85×2=15.7 inches.
- Add the rim diameter: 15.7 inches+17 inches=32.7 inches15.7 inches plus 17 inches equals 32.7 inches15.7 inches+17 inches=32.7 inches.
This shows why a 285/70R17 is often referred to as a "33-inch" tire, even though it is slightly smaller.
