What tire size comes stock on an F150?

The base tire size of a 2015 Ford F-150 pickup truck is P245/70R17 for use on the base F150's 17-inch wheels. Most base model F-150s use 17-inch wheels, though exact tire sizes may vary from year to year.

Many Ford F-150 trucks have larger rims and tire sizes than standard if they are equipped with option packages, such as the 20-inch rims used on the F-150 Platinum trim model. There may be additional options for different wheel styles on these trims that result in different tire sizes even for vehicles with the same wheel size, so it is important for owners to verify which tire size is correct for their vehicles before purchasing or installing new tires.
