What this size means for your GMC Yukon
On the 2003 GMC Yukon XL 1500 2wd, the factory 265/70R16 measures about 30.6″ in overall diameter with a 185.5 mm (7.3″) sidewall, and completes roughly 659 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 265/70R16 and 265/70R17 differ by about 1″ (3.3%) in overall diameter; a gap this size is enough to affect speedometer and odometer readings, so confirm which one your vehicle actually left the factory with.
On a vehicle of this age, the GMC Yukon 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.
