Ford F-250 Tire Size Guide: OEM, Plus-One & Off-Road Options by Year

You're standing in a tire shop parking lot, staring at a wall of rubber that runs from sedan-skinny to tractor-wide. The guy behind the counter asked what size you need for your F-250, and you blanked. Happens to almost everyone. The Super Duty ships across a wide spread of trims and model years, and Ford has fit it with everything from a modest 265/70R17 on a base XL to a beefy 275/65R20 under a Platinum. This guide lays out the factory sizes by year, walks the plus-one path, and maps the off-road builds worth running.

Most F-250 Super Dutys roll off the lot on 265/70R17, 275/70R18, or 275/65R20 tires depending on trim and year. XL and XLT typically wear 17-inch wheels; Lariat and King Ranch step up to 18s; Platinum and Limited run 20s. A plus-one upgrade adds one inch of wheel diameter without touching the suspension. Off-road builds commonly run 35-inch tires on a 2-inch leveling kit with no rubbing.

F-250 Factory Tire Sizes by Year and Trim

Ford's third-gen Super Duty (2017 forward) reset the baseline. Before then, the trims shared more wheels. From 2017 on, tire fitment tracks your trim more than your year. XL and XLT ride on 17s. Lariat and King Ranch pull 18s. Platinum and Limited get the 20-inch package.

The 4x2 and 4x4 configurations share the same fitment on almost every trim. Ford specs it that way so the suspension geometry and speedometer stay consistent. What changes between them is ride height and offset, not the rubber.

Here's the chart most owners actually need:

Trim	2017-2019	2020-2022	2023-2025
XL / XLT	LT245/75R17 or 265/70R17	265/70R17	265/70R17
Lariat	LT275/70R18	LT275/70R18	LT275/70R18
King Ranch	LT275/70R18	LT275/70R18	LT275/70R18
Platinum	275/65R20	275/65R20	275/65R20
Limited	275/65R20	275/65R20	275/65R20
Tremor (2020+)	n/a	LT275/70R18 A/T	LT275/70R18 A/T

Use this chart to match your trim and year. Then double-check the yellow door-jamb sticker before you buy. Factory options like the FX4 or Tremor package can shift you up a tier. For anything odd, cross-reference the Ford spec page with your VIN build sheet.

Most guides list one fitment per year and call it done. That leaves half the Super Duty lineup guessing. If you own a base XL 4x4 with steel wheels, you're on 17s. If you're driving a Platinum, you're on 20s and paying accordingly for replacement rubber.

How to Read an F-250 Tire Size Code

Look at the sidewall. You'll see something like LT275/70R18 Load Range E. Each part means something.

LT, light truck rating. Higher load capacity than a P-metric (passenger) tire. The Super Duty runs LT for a reason. Its GVWR touches 10,000 lbs on most setups.

275 — section width in millimeters.

70, aspect ratio. The sidewall height is 70% of the section width.

R — radial construction.

18 — wheel diameter in inches.

Load Range E, the load capacity rating. E is roughly a 10-ply equivalent, built to carry heavy payload at 80 PSI cold.

The most common mid-tier Super Duty spec is LT275/70R18 Load Range E. That's what a Lariat or King Ranch wears from the factory. It's rated to support the truck's full payload without deflecting.

Load Range D exists on some light-duty applications. Do not drop your F-250 to a D rating if you tow or haul near your limits. You lose sidewall stiffness and heat capacity right where you need it most.

The door-jamb placard is the final word. Ford prints the factory fitment and the recommended cold inflation front and rear right on that sticker. If your driver's door sticker says LT275/70R18, that's your fitment. Same rule applies when checking whether steering wheel covers fit all trucks the same way. Fitment lives on the vehicle, not the box.

Plus-One Tire Upgrades for the F-250

What Plus-One Means in Practice

Plus-one sizing bumps your wheel diameter up by one inch and drops the sidewall to keep the overall diameter close to stock. You get a wider tread footprint, a shorter sidewall, and a sharper look. You lose a little ride comfort and a bit of pothole forgiveness.

The math matters. If your new tire's overall diameter differs from stock by more than 3%, your speedometer will read off. Your ABS and traction control also use that diameter as a reference point. Stay within 3% and everything talks to itself correctly. Go over and you'll need a programmer or a dealer recalibration.

Recommended Plus-One Sizes by Stock Fitment

Stock Size	Plus-One Size	Diameter Change
265/70R17	285/65R18	+0.4%
LT275/70R18	285/60R20	-1.9%
275/65R20	285/55R22	-1.2%

A 285/65R18 on an 18-inch wheel is the most common plus-one swap from a stock 265/70R17. It fits the fender well without a lift. It sits close to factory diameter and gives you a broader footprint for towing stability.

I've seen owners on 17-inch XLs jump straight to a 20-inch wheel and hate the ride within a month. Two inches of wheel is a plus-two, not a plus-one. Your kidneys will notice every expansion joint on I-40. Stick to a single inch bump and the trade-offs stay in your favor.

Off-Road Tire Options and Lift Requirements

35-Inch Tires: The Most Popular Off-Road Upgrade

35s are the sweet spot for the Super Duty. Big enough to clear rocks and ruts, small enough to run without cutting sheet metal.

On a 4x4 F-250 with a 2-inch leveling kit, a 35x12.50R17 or 35x12.50R18 fits without rubbing at full lock. The leveling kit lifts the front end to match the factory rear ride height. This opens up the front wheel well. On a completely stock suspension, 35s will contact the front inner fender when you turn hard. Ask anyone with a stock XLT who tried it in a parking lot.

A 4x2 F-250 sits lower up front and has less wheel well clearance to start with. Same 35s on a 4x2 usually need a taller leveling kit or minor fender trimming. Most off-road guides skip this detail. It matters.

37-Inch Tires: What You Need Before You Buy

37s change the game. You're now looking at a 4-inch suspension lift at minimum, plus fender trimming or aftermarket flares. On a stock F-250 the 37s will rub the front inner fender at full lock. They'll also rub the rear bump stops under compression.

Budget for the whole build: lift kit ($1,500—$3,000), wheels and tires ($2,000, $3,500), gear regear on higher-mileage trucks, and a recalibration. This isn't a Saturday afternoon job.

Tread pattern matters too. All-terrain (A/T) tires like the Toyo Open Country A/T III give you 80% highway manners with real dirt capability. Mud-terrain (M/T) tires like the BFGoodrich KM3 will chew a trail but they howl on the highway and drop your MPG by 1-2 on average.

Tire Pressure Settings for the F-250

Check the yellow door-jamb placard. Ford's number is the number. That's cold inflation, measured before you drive.

Most F-250s call for around 60-65 PSI front and 65-80 PSI rear depending on your load range and payload. The rear runs higher because the rear axle carries more weight, especially when you're loaded or towing.

When you're loaded near max payload or pulling a heavy trailer, bump the rear cold pressure toward the upper limit on the placard. LT tires are built to hold 80 PSI when they're carrying full load. That's not a suggestion. It's how they stay cool and how the sidewall stays stable at highway speed.

Ford recommends checking pressure monthly and before any tow over 5,000 lbs. If you swap to aftermarket wheels, your TPMS sensors need to move over too. New sensors and a relearn procedure aren't optional. That dash light gets ignored by too many owners until it's inspection time.

Wheel Backspacing and Offset Basics for F-250 Fitment

Backspacing is the distance from the back of the wheel to the mounting face. Offset is how far the mounting face sits from the wheel's centerline. Both control how far your tire sits in or out of the fender.

Factory backspacing on most F-250 trims sits near 4.75 inches. That places the tire right where Ford's suspension engineers wanted it. It stays inside the fender, clear of the steering knuckle, aligned with the bearing load path.

Going more negative (pushing the wheel outward with a lower backspacing number) gives you that wider stance. It also puts more leverage on your wheel bearings and can void the powertrain warranty if a dealer decides the aftermarket setup caused a failure. I've watched a guy burn through a set of front bearings in 20,000 miles on 8-inch backspacing wheels. Not worth it.

Bolt pattern is 8x170mm across every Super Duty from 1999 to today. That makes wheel swaps between model years easy. But backspacing changed subtly over the generations. A 2005 wheel on a 2023 F-250 may not sit correctly even with the right bolt pattern.

Protecting Your F-250 Interior While You Run the Right Tires

Here's what nobody tells you when you buy 35-inch mud-terrains. The mud comes with you into the cab. Gravel, sand, chunks of trail all end up on your floor mats and worked into the seat bolsters within a month.

If your F-250 doubles as a work truck, the wear accelerates fast. Toolbelts on the driver's seat, dogs in the passenger seat, kids climbing over the console after a Little League game. The factory cloth on an XL or XLT is durable, but it's not designed for that daily punishment. Lariat leather looks nice for two years, then the driver's bolster starts to crack from the daily in-and-out.

This is where made-to-fit seat covers for the F-250 earn their keep. Tailored to your exact trim and year, cut around the side airbags, installed in under an hour. They take the beating so your factory seats don't. A set of luxury seat covers protects your investment through years of trail runs and work-site duty.

If you own or plan to grab a two-door Bronco alongside your Super Duty, the same fit philosophy applies to those seat covers ford bronco owners rely on.

F-250 Tire Brand Recommendations by Use Case

Pick your tire by how you actually use the truck, not by what looks cool in the parking lot.

Highway and towing. The Michelin Defender LTX M/S is the benchmark. Quiet, long wearing, holds pressure well under load. The BFGoodrich Commercial T/A A/S 2 is the fleet favorite for a reason. It's built for weight and mileage. If you tow more than 5,000 lbs weekly, you want one of these two.

All-terrain daily driver. The Toyo Open Country A/T III has taken over the market for a good reason. Balanced tread, quiet on the interstate, real bite on gravel and mud. The Falken Wildpeak A/T3W is a close second and usually undercuts Toyo on price at any independent tire shop.

Mud-terrain trail rig. The BFGoodrich KM3 is the standard everyone measures against. The Nitto Trail Grappler runs it close and is a little quieter on the highway. Both will drop your fuel economy by 1-2 MPG versus a highway tire. That's not marketing hedge. That's what owners report on the same truck before and after.

For related fitment questions like how to size a steering wheel cover for your truck, the same rule applies. Measure the vehicle, don't guess by model name.

Frequently Asked Questions

Q: What is the stock tire size on a 2023 Ford F-250?

The 2023 F-250 XL and XLT ship on 265/70R17 tires. Lariat and King Ranch run LT275/70R18. Platinum and Limited use 275/65R20. Trim level is the deciding factor, not the engine or cab configuration. The 4x2 and 4x4 versions of the same trim share the fitment. Confirm your exact spec on the yellow door-jamb placard before you order replacements.

Q: Can I put 35-inch tires on a stock F-250 without a lift?

On a 4x4 F-250 with a 2-inch leveling kit, yes. 35s fit without rubbing at full lock and clear the front bumper under normal driving. On a completely stock suspension with no leveling kit, 35s will contact the front inner fender when you turn hard. A 4x2 F-250 sits lower up front and usually needs a taller leveling kit or minor fender trimming to run the same fitment cleanly.

Q: What bolt pattern does the Ford F-250 use?

The F-250 Super Duty uses an 8x170mm bolt pattern across every generation from 1999 to today. That makes wheel swaps between model years straightforward on paper. Backspacing still needs to match, though. An older wheel may not sit in the fender correctly even with the right bolt pattern. Always mock up before you commit to a full set.

Q: Does changing tire size affect the F-250 speedometer?

Yes. If your new tire's overall diameter differs from stock by more than about 3%, your speedometer will read off. Go bigger and your speedo will read low (you're actually going faster than it shows). A programmer like a SCT or a dealer recalibration corrects the reading. It also resets the ABS and traction control thresholds that use tire rotation speed as a reference.

Q: What load range tire does the F-250 need?

Ford fits Load Range E (10-ply equivalent) tires from the factory on most F-250 trims. That rating supports the truck's GVWR up to 10,000 lbs and its towing capacity. Dropping to Load Range D is not recommended if you tow, haul, or run heavy in the bed. The sidewall stiffness and heat capacity of an E-rated tire is what keeps you safe at highway speed under load.

Q: How much does it cost to replace all four tires on an F-250?

Expect $900 to $1,800 for a set of four, depending on brand, fitment, and tread type. Highway tires run at the low end. All-terrains sit in the middle. Mud-terrains and 35-inch off-road tires push toward the high end and beyond. Installation, balancing, valve stems, and disposal typically add $80 to $150 on top. Larger 20-inch Platinum and Limited fitments cost more per tire than 17s or 18s.

Once your tire fitment is sorted, take five minutes to lock in made-to-fit seat covers shaped for your exact F-250 build. Grab a set of luxury seat covers before the next muddy trail run leaves its mark.
