A 1985 Lamborghini Countach (LP5000 QV) was originally equipped with an 18-inch Michelin space-saver spare tire.
While the standard road tires for the 1985 model were 15-inch Pirelli P7R tires, the spare wheel was intentionally oversized in diameter to clear the brake calipers while remaining narrow enough to fit in the front trunk (frunk).
