What this size means for your Ford Taurus
On the 2013 Ford Taurus SHO, the factory 255/45R19 measures about 28″ in overall diameter with a 114.8 mm (4.5″) sidewall, and completes roughly 719 revolutions per mile. Its 45-series aspect ratio gives a low-profile sidewall tuned for sharper handling, common on sport trims and larger-wheel packages. In tire terms it is a passenger (P-metric / Euro-metric) size.
The 255/45R19 and 245/45R20 differ in both width and overall diameter (0.7″, 2.5%), which usually means a staggered front/rear setup — the two sizes are not interchangeable side to side, so match each to its correct axle.

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.
