What this size means for your Ford Mustang
On the 2011 Ford Mustang Coupe Automatic Transmission, the factory 225/60R17 measures about 27.6″ in overall diameter with a 135 mm (5.3″) sidewall, and completes roughly 730 revolutions per mile. Its 60-series aspect ratio gives a taller, comfort-biased sidewall that favors ride quality and shrugs off rough pavement. In tire terms it is a passenger (P-metric / Euro-metric) size.
The 225/60R17 and 235/50R18 roll within 0.3″ (1.1%) of each other in overall diameter, so they are interchangeable from a speedometer standpoint — the second size is an optional wheel package rather than a different rolling size.

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.
