What size tires come on a common F150?
The factory tire size most commonly found on a standard Ford F-150 is 265/70R17 on 17-inch wheels. However, tire size varies by model year and trim, with many trucks upgrading to larger wheels and correspondingly larger tires.
Understanding stock tire sizes across years and trims
To help you quickly identify what you might find on a typical modern F-150, here are the tire sizes most frequently paired with common wheel sizes from recent model years. Note that exact specifications can differ by trim and production year, so always verify on the door jamb placard or in the owner's manual.
- 17-inch wheels: P265/70R17
- 18-inch wheels: P275/65R18
- 20-inch wheels: P275/55R20
These sizes represent the typical factory configurations for many base, XLT, and higher trims when equipped with standard or commonly chosen wheel setups. For any tire upgrade or replacement, ensure the new tires maintain a similar overall diameter to avoid speedometer errors and changes in gearing or traction control behavior.
Notes on trims and off-road variants
Some higher-end or off-road-focused variants can use different tire sizes, especially if they come with unique suspension or larger diameter wheels. Always check the exact specification for your particular truck, as the same model year can offer multiple factory tire options depending on the package or wheel choice.
Why tire size matters
Tire size affects several aspects of vehicle performance, including ride quality, handling, speedometer accuracy, and load capacity. If you’re changing wheel diameters or going with an aftermarket size, factor in these considerations and consider a professional alignment or recalibration if necessary.
Summary
In short, the most common factory tire sizes for an F-150 are 265/70R17 on 17-inch wheels, 275/65R18 on 18-inch wheels, and 275/55R20 on 20-inch wheels, with variations by year and trim. Always confirm the exact size listed on the door placard for your specific truck and year, especially before purchasing replacements or upgrades.
