1992 Geo Metro — Convertible
The 1992 Geo Metro Convertible came from the factory equipped with 165/65R13 tires. If your vehicle has since been fitted with aftermarket or upsized wheels, your actual tire size may no longer match this factory spec — always confirm against your door placard before buying.

What this size means for your Geo Metro
On the 1992 Geo Metro Convertible, the factory 165/65R13 measures about 21.4″ in overall diameter with a 107.3 mm (4.2″) sidewall, and completes roughly 940 revolutions per mile. Its 65-series aspect ratio gives a taller, comfort-biased sidewall that favors ride quality and shrugs off rough pavement. In tire terms it is a small-diameter fitment typical of older or economy vehicles.
Because the 1992 Geo Metro 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.
