What this size means for your Dodge Viper
On the 2002 Dodge Viper GTS, the factory 275/35R18 measures about 25.6″ in overall diameter with a 96.3 mm (3.8″) sidewall, and completes roughly 788 revolutions per mile. Its 35-series aspect ratio gives an ultra-low-profile, performance-oriented sidewall that favors steering precision over ride cushioning. In tire terms it is a passenger (P-metric / Euro-metric) size.
This is a staggered setup: the front axle runs 275/35R18 and the rear runs 335/30R18. The two sizes are not interchangeable, so order each for its correct axle and don't rotate front-to-rear.
On a vehicle of this age, the Dodge Viper 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.
