What this size means for your Ford Bronco
On the 2026 Ford Bronco Raptor, the factory 37X12.50R17 is a flotation off-road size, quoted directly in inches rather than metric — about 37″ tall and 12.5″ wide on a 17″ wheel, turning roughly 545 revolutions per mile. Flotation sizes like this are chosen for traction and ground clearance rather than on-road refinement.

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.
