What this size means for your Chevrolet Silverado
On the 2001 Chevrolet Silverado 2wd Dually, the factory 215/85R16 measures about 30.4″ in overall diameter with a 182.8 mm (7.2″) sidewall, and completes roughly 664 revolutions per mile. Its 85-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 215/85R16 and 225/75R16 differ in both width and overall diameter (1.1″, 3.8%), 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 Chevrolet Silverado 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.
