What this size means for your Lamborghini Countach
On the 1988 Lamborghini Countach 5000 quattrovalvole, the factory 225/50R15 measures about 23.9″ in overall diameter with a 112.5 mm (4.4″) sidewall, and completes roughly 845 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 225/50R15 and the rear runs 345/35R15. The two sizes are not interchangeable, so order each for its correct axle and don't rotate front-to-rear.
Because the 1988 Lamborghini Countach 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.
