What this size means for your Aston Martin Vantage
On the 2023 Aston Martin Vantage V12, the factory 255/40R20 measures about 28″ in overall diameter with a 102 mm (4″) sidewall, and completes roughly 719 revolutions per mile. Its 40-series aspect ratio gives a low-profile sidewall tuned for sharper handling, common on sport trims and larger-wheel packages. In tire terms it is a large-diameter fitment.
This is a staggered setup: the front axle runs 255/40R20 and the rear runs 295/35R20. 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.
