2019 Ford F-250 Super Duty Tire Size & Pressure Guide

As an ASE-certified master technician, I’ve seen my fair share of heavy-duty trucks roll into the shop. The 2019 Ford F-250 Super Duty is an absolute workhorse, but to safely utilize its massive towing and payload capabilities, you need to ensure your tires and wheels are up to the task. Fitting the wrong load range or running improper pressures on a three-quarter-ton truck is a recipe for accelerated wear, poor handling, and catastrophic blowouts under load.

Here is your comprehensive reference guide for the 2019 Ford F-250 Super Duty tire sizes, pressures, and wheel specifications.

Quick Answer: 2019 Ford F-250 Super Duty Tire & Wheel Specs

If you are just looking for the hard numbers, here are the baseline specifications for a standard single rear wheel (SRW) 2019 F-250:

• OEM Tire Sizes: LT245/75R17, LT275/65R18, LT275/70R18, or LT275/65R20 (depending on trim and options)
• Recommended Cold Tire Pressure (Unloaded): 60 PSI Front / 65 PSI Rear (Check your driver’s side door jamb placard, as this varies by cab configuration and engine weight)
• Bolt Pattern: 8x170mm
• Wheel Sizes: 17x7.5, 18x8.0, or 20x8.0 (Offsets typically range from +40mm to +44mm)
• Load Index & Speed Rating: 121/118S up to 126/123R (Must use Load Range E / 10-ply rated tires)
• Spare Tire Size: Full-size matching spare (steel wheel)
• TPMS Frequency: 315 MHz

Tire Sizes by Trim

Ford offered a variety of wheel and tire packages depending on the trim level and whether the truck was equipped with the FX4 Off-Road package.

Recommended Replacement Tires

When replacing tires on an F-250, you must choose a Load Range E (10-ply) tire. Passenger (P-metric) tires are dangerous and illegal to install on this weight class. Here are my top picks based on customer feedback and shop experience:

• Premium Tier ($$$): Michelin Defender LTX M/S
  • Best for: Highway driving, towing, and longevity. These run quiet and routinely last 60,000+ miles even with frequent towing.
• Mid-Tier / All-Terrain ($$): BFGoodrich All-Terrain T/A KO2
  • Best for: Job sites, off-roading, and snow. A legendary A/T tire with aggressive sidewalls and excellent puncture resistance.
• Value Tier ($): Cooper Discoverer AT3 XLT
  • Best for: Budget-conscious drivers who still need heavy-duty towing capacity and decent off-road traction without breaking the bank.

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 sedan. The door placard gives you the recommended pressure for everyday driving and standard payloads (often 60 PSI front, 65 PSI rear).

However, Load Range E tires have a maximum cold inflation pressure of 80 PSI.

• When to use 80 PSI: You should only inflate your rear tires to 80 PSI when you are maxing out your truck's payload capacity or towing a very heavy gooseneck/fifth-wheel trailer with high pin weight.
• Why drop it back down? Once you drop the trailer, riding around empty with 80 PSI in the rear will give you a bone-jarring ride, cause the center of the tread to wear out prematurely, and reduce traction on wet roads.

Lug Nut Torque & Pattern

• Bolt Pattern: 8x170mm (Standard for Ford Super Duty trucks since 1999)
• Lug Nut Torque: 150 lb-ft

Technician Tip: Always use a calibrated torque wrench. Over-torquing with an impact gun can stretch the wheel studs or warp the brake rotors. Re-torque the lug nuts after 50 to 100 miles of driving anytime the wheels are removed.

Common Tire Issues for this Vehicle

1. Front-End Cupping: The F-250's solid front axle is heavy. If the front shocks begin to wear out or if tire rotations are neglected, you will quickly develop cupping (scalloping) on the inside edges of the front tires, leading to a loud "womp-womp" noise at highway speeds.
2. Death Wobble: While not strictly a tire issue, unbalanced tires or tires with a shifted belt can trigger the dreaded Ford "death wobble" if the track bar bushing or steering stabilizer is slightly worn.
3. TPMS Sensor Failure: The factory 315 MHz sensors have internal batteries that typically last 5 to 7 years. For a 2019, you are entering the window where the batteries might start dying, triggering the dashboard TPMS light.
