2017 Ford F-250 Super Duty Tire Size, Pressure & Wheel Specs

The 2017 Ford F-250 Super Duty is a workhorse engineered for heavy hauling, towing, and severe-duty applications. Because of its massive capabilities, running the correct tires at the proper inflation pressures is critical for safety, vehicle stability, and tire longevity. As an ASE-certified master technician, I regularly see these trucks in the shop, and ensuring they have the right Load Range E tires is priority number one.

Here is your comprehensive guide to the 2017 Ford F-250 Super Duty tire and wheel specifications.

Quick answer

• OEM Tire Size: 245/75R17, 275/65R18, 275/70R18, or 275/65R20 (depending on trim and options)
• Recommended Cold Tire Pressure: 60 PSI Front / 65–80 PSI Rear (check your driver's side door placard, as diesel vs. gas engines and payload packages alter this number)
• Bolt Pattern: 8x170mm
• Wheel Size: 17x7.5, 18x8, or 20x8 (Offsets vary from +40mm to +44mm)
• Load Index / Speed Rating: 121/118S or 125/122S / Load Range E (10-ply rated) is strictly required for this 3/4-ton truck.
• Spare Tire Size: Matches the overall diameter of the factory tires, typically a 245/75R17 or 275/70R18 on a basic steel wheel.
• TPMS Frequency: 315 MHz

Tire sizes by trim

Ford offered several wheel and tire packages across the 2017 F-250 lineup. Below are the most common OEM sizes by trim level:

(Note: Always verify your specific truck's tire size on the tire sidewall or door jamb placard, especially if you bought the truck used, as previous owners frequently upgrade wheel sizes.)

Recommended replacement tires

When replacing tires on your F-250, you must choose LT-metric tires with a Load Range E to support the truck's weight and towing capacity. Never install standard P-metric passenger tires on a Super Duty.

1. Michelin Defender LTX M/S – Premium ($$$): An industry favorite for heavy-duty trucks driven mostly on the highway. Exceptional tread life, quiet ride, and excellent wet traction.
2. BFGoodrich All-Terrain T/A KO2 – Mid-to-High ($$ - $$$): The go-to choice if you need aggressive off-road capability, snow rating (3PMSF), and strong puncture resistance for job sites.
3. Falken Wildpeak A/T3W – Mid-Range ($$): A superb value that offers great wet/snow performance and long tread life without the premium price tag of the BFG or Michelin.
4. Cooper Discoverer HT3 – Budget/Mid-Range ($): A solid highway-terrain commercial truck tire that excels in fleet use or daily driving where extreme off-roading isn't required.

When to inflate to max load psi

Because the F-250 is a Heavy Duty truck, tire pressure management is a bit different than on a standard passenger car. The sidewall of a Load Range E tire will typically list a maximum cold pressure of 80 PSI.

When should you run 80 PSI? You should only inflate the rear tires to 80 PSI when you are heavily loaded, maxing out your payload in the bed, or towing a heavy fifth-wheel/gooseneck trailer with high pin weight. Running 80 PSI in the rear while the truck is completely empty will result in a harsh, jarring ride and premature center-tread wear. Always consult the door placard for the recommended daily driving pressures (often 60 PSI front and 65 PSI rear) and adjust up to 80 PSI in the rear only when the load demands it.

Lug nut torque & pattern

Super Duty trucks require significant clamping force. Ensure your wheels are torqued correctly using a calibrated torque wrench in a star/cross pattern.

• Bolt Pattern: 8x170mm
• Lug Nut Torque: 165 ft-lbs (224 Nm)
• Lug Nut Thread Size: M14 x 1.5

Tech Tip: Re-torque your lug nuts after the first 50 to 100 miles of driving after a wheel installation or tire rotation, as heavy-duty wheels can settle and cause lug nuts to loosen slightly.

Common tire issues for this vehicle

• Uneven Front Tire Wear (Cupping/Feathering): The heavy front end of the F-250 (especially with the 6.7L Power Stroke diesel engine) puts a lot of stress on the front suspension. Worn shocks or steering linkage (like the track bar or tie rods) can lead to tire cupping or outer edge wear. Regular alignments and frequent tire rotations (every 5,000 miles) are mandatory.
• TPMS Sensor Failure: The factory 315 MHz sensors have batteries that typically last 7 to 10 years. For a 2017 model, you are approaching the window where sensor batteries may start dying, triggering the TPMS light on your dash.
• Death Wobble: While primarily a suspension issue (track bar bushing/ball joint failure), severely unbalanced or unevenly worn front tires can trigger or exacerbate the dreaded Super Duty "death wobble" at highway speeds. Keep those front tires perfectly balanced!
