What this size means for your Nissan 370Z

On the 2016 Nissan 370Z Coupe, the factory 225/50R18 measures about 26.9″ in overall diameter with a 112.5 mm (4.4″) sidewall, and completes roughly 751 revolutions per mile. Its 50-series aspect ratio gives a balanced everyday-passenger profile — enough sidewall to soak up road shock while keeping steering response crisp. In tire terms it is a passenger (P-metric / Euro-metric) size.

This is a staggered setup: the front axle runs 225/50R18 and the rear runs 245/45R18. The two sizes are not interchangeable, so order each for its correct axle and don't rotate front-to-rear.

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.
