What this size means for your Chevrolet S10

On the 1994 Chevrolet S10 ZR2, the factory 31X10.50R15 is a flotation off-road size, quoted directly in inches rather than metric — about 31″ tall and 10.5″ wide on a 15″ wheel, turning roughly 651 revolutions per mile. Flotation sizes like this are chosen for traction and ground clearance rather than on-road refinement.

Because the 1994 Chevrolet S10 predates many current tire lines, confirm this size is still stocked before ordering — some vintage fitments are now served mainly by specialty and classic-car tire suppliers.

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.
