What this size means for your Ford F150

On the 2003 Ford F150 Super Crew 4wd, the factory 255/70R16 measures about 30.1″ in overall diameter with a 178.5 mm (7″) sidewall, and completes roughly 671 revolutions per mile. Its 70-series aspect ratio gives a tall sidewall of the kind used on trucks, SUVs, and older passenger cars, built for cushioning and load. In tire terms it is a passenger (P-metric / Euro-metric) size.

The 255/70R16 and 265/70R17 differ in both width and overall diameter (1.5″, 5%), which usually means a staggered front/rear setup — the two sizes are not interchangeable side to side, so match each to its correct axle.

On a vehicle of this age, the Ford F150 may have been refitted with a slightly different replacement size somewhere in its life, so check the current sidewall — not just the factory spec — before buying.

How to read a tire size

A tire size like 225/45R17 breaks down into three parts: the first number is the section width in millimeters (the tire's width from sidewall to sidewall), the second is the aspect ratio — the sidewall's height as a percentage of that width — and the number after the "R" is the rim diameter in inches. A letter prefix (P or LT) indicates Passenger or Light Truck construction; its absence usually means Euro-metric sizing.

Some trucks and off-road tires instead use "flotation" sizing, like 37X12.50R17 — here the numbers are the tire's overall diameter and width in inches directly, with the rim diameter last.

Always verify against the tire information placard on your driver's-side door jamb or your owner's manual before purchasing — tire size can vary by factory option package even within the same trim.
