Ford tire sizes

We cover 49 Ford models across 148 factory fitments, spanning model years 1953 to 2024. The size that turns up most often on a Ford is 245/45R17, followed by 37x12.50R17 and 225/60R16. Wheel diameters run from 14 to 24 inches, so the trim and wheel package matter as much as the model year.

Ford does not stamp an approval code on tires the way Porsche and BMW do, so any tire in the right size that meets the load index and speed rating on the door placard is a legitimate replacement. Pick on wet braking, tread life and price instead.

Pick your model below to see the size for every year and trim, what it costs from budget to premium, and which tires are worth buying in that size. If you already know your size, search by size instead, and if you are not sure where to find it, our guide on reading a tire size shows exactly where the placard sits.

Ford sells close to two million vehicles a year in the United States and the F-Series has been the best-selling vehicle in the country for over four decades. The modern lineup is almost entirely trucks and crossovers, with the Mustang as the last car, and the electric F-150 Lightning and Mustang Mach-E alongside them. Ford's tire story is dominated by the F-Series trim walk, which alone spans five wheel diameters and dozens of sizes.

Its back catalog of Mustangs, Broncos and F-100s is one of the largest classic parcs in America.

Tires on a Ford

Ford stamps no approval code on its tires, so unlike a BMW or a Mercedes there is no letter to match, and the door placard is the complete specification. What Ford does instead is co-develop specific OE tires per model, which is why a Raptor arrives on a BFGoodrich all-terrain and a Lariat on a highway all-season in a size the Raptor never uses. The F-150 alone runs 245/70R17 on an XL, 275/65R18 on an XLT or Lariat, 275/60R20 higher up and 275/45R22 on a Limited or Platinum, and the aftermarket adds 33 and 35 inch fitments that we list because so many trucks are on them.

Super Duty trucks move to LT-rated sizes such as LT275/70R18 and LT275/65R20 that run 65 to 80 psi, and dual-rear-wheel trucks need six tires. Fitments are square everywhere except the Mustang GT with the Performance Pack and the Ford GT, which is staggered at 245/30R20 front and 325/30R20 rear. Owners replace truck all-seasons with all-terrains more often than in any other segment, and the single most common mistake is buying four when a Super Duty dually needs six, or buying a P-metric tire to replace an LT one on a truck that tows.

The models that matter

The F-150 is the volume model and the deepest fitment list on the site, from 245/70R17 up to 275/45R22. The Explorer runs 255/65R18 or 255/55R20, the Escape 225/60R17 or 225/55R19, and the Bronco 255/70R17 with 285/70R17 on a Badlands and 37 inch tires on a Raptor. The Mustang takes 235/50R18 on EcoBoost and GT and 255/40R19 with the Performance Pack, and the electric Mach-E runs 225/60R18, 225/55R19 or 245/45R20.

What owners find out later

Replacing an LT tire with a P-metric one in the same nominal size drops the load capacity substantially, which matters the first time you hitch a trailer and is the most consequential Ford tire mistake. The Bronco and Raptor's 35 and 37 inch tires are heavy enough that the spare alone is a two-person lift, and a full-size spare that matches the other four is standard on those trucks but not on most. Ford's direct TPMS needs a relearn with a tool after rotation on many trucks.
