Ford F-150 tires

There is no single F-150 tire size and no single F-150 tire pressure. The truck is sold on everything from a 17 inch work tire to a 22 inch low-profile one, the sizes changed when the generation changed in 2021, and the correct pressure is printed on your truck rather than in Ford's manual.

The sizes Ford fitted

On the 14th generation truck, from 2021, the recorded fitments are:

Size	Trims
265/70R17 115T	XL 4x4, XLT 4x4
275/65R18 116T	XL 4x4, XLT 4x4, Lariat 4x4, King Ranch 4x4
275/60R20 115T	XL, XLT, Lariat, King Ranch, Platinum
275/50R22 111T	Limited
LT275/65R18 load range C	Heavy Duty Payload Package trucks
LT315/70R17 load range C, or 37x12.50R17LT	Raptor and Raptor R

The 13th generation truck, through 2020, is not the same. It ran 275/55R20 where the newer truck runs 275/60R20, and P275/45R22 on the Limited where the newer truck runs 275/50R22. Order by trim name across the 2020 to 2021 boundary and you get the wrong tire.

If the wheels have ever been swapped, the size on the truck may not be the size on the placard either, and the placard figure then becomes a starting point rather than an answer. See finding your tire size.

Where the F-150 hides its tire label

Ford puts the tire label on the B-pillar or on the edge of the driver door. The B-pillar is the upright post behind the driver's door, the one you see when the door is open and you look at the body rather than at the door. The same pressures appear on the Safety Compliance Certification Label, which the manual places on the door hinge pillar, the door-latch post, the door edge that meets the latch, or the edge of the driver door.

That spread is why owners check the door edge, find nothing, and go searching online instead. Check the post, at about shoulder height.

Reading it, and why there is no number to give you

The label carries four things: cold pressure front, cold pressure rear, the original tire size and the spare. Cold means parked at least three hours or driven under a mile. A warm tire reads high, so bleeding air down to the placard figure after a drive leaves you underinflated once it cools.

Page 554 of the 2023 manual covers cold inflation pressure and prints no figure. It says only that you will find the tire label with the recommended pressure next to the tire size, and to use that recommended cold pressure. With this many fitments across two tire constructions, one number would be wrong for most trucks.

The tire-pressure lookup sites fill the gap by guessing, and they disagree. On the heavy-duty-payload LT fitment, one gives 48 psi and another gives 40. Eight PSI on a tire that is carrying weight is not something you average. Underinflate a loaded LT tire and it runs hot, and heat is how sidewalls fail. More in our tire pressure placard guide.

Replacing one or two instead of four

Ford asks for replacement tires of the same size, load index, speed rating and type as the originals, and for two front or two rear tires to be replaced as a pair where the worn ones still have usable depth. There is no four-wheel-drive-specific rule in the manual and no numeric tread-depth tolerance in it. On a 4x4 with three well worn tires you are choosing between a set and a compromise, and we will say which we think you are looking at. See how many tires and mixing tire brands.

Do not put a standard P-metric tire on a Heavy Duty Payload truck. The load range is doing real work there.

What changes on a mobile F-150 fitting

• Wheel nut torque is 150 lb-ft on M14 x 1.5 studs, and Ford states that figure assumes clean threads and a mounting surface free of corrosion.
• Ford's two-piece capped lug nuts are a known failure here. The cap swells over the steel core and delaminates until the supplied wrench no longer fits, which has left owners unable to remove a wheel roadside. We carry oversize sockets and an extractor set.
• TPMS is one sensor per wheel at the valve stem. The relearn is a deflate-until-the-horn-sounds sequence, left front, right front, right rear, left rear, then reinflate to placard.
• The spare hangs under the truck forward of the rear bumper, on a cable winch worked with the jack handle.
• Raptor sizes need a high-capacity bead breaker, and the 22 inch Limited fitment leaves little sidewall protecting the rim.
• A TPMS lamp lit after airing down off-road is the system working, not a fault.

What we do

We supply the tires and fit them where the truck is parked. Every tire is set to the placard pressure read off that truck, the TPMS is reset or relearned where supported, nuts go to spec at 150 lb-ft, and the old tires leave with us. Costs are on our mobile tire replacement page.

Questions people ask

• What PSI should my F-150 be at? Whatever the label on your B-pillar or door edge says for that axle and tire size. Ford prints no figure, and the lookup sites differ by eight PSI on the heavy-payload fitment.
• My door edge has no sticker. Where else? The B-pillar, the post behind the door.
• Can I fit a normal tire to a Heavy Duty Payload truck? Not safely. Those run LT-metric load range C or E tires and the load rating has to be matched, not just the size.
• My lug nuts are swollen and the wrench will not fit. Common here, and it is the capped nut design rather than anything you did. We carry extractors and fit replacement nuts.
• Can you fit just one tire? Yes, though Ford asks for pairs where the other tires still have usable depth.
