What is the tire specification of the Audi A8?
2 Answers
Audi A8's original tire specification is: 255/40-R19. The main brands of Audi A8's original tires are: Dunlop, Michelin, and Bridgestone. Introduction to car tires: Tires are ring-shaped elastic rubber products mounted on various vehicles or machinery for ground rolling. They are usually installed on metal rims, supporting the vehicle body, cushioning external impacts, achieving contact with the road surface, and ensuring the vehicle's driving performance. Composition of car tires: Tires are generally composed of three parts: the outer tire, inner tube, and flap. Some tires do not require an inner tube, featuring an inner layer with highly airtight rubber, and require specialized rims. The structure of tires worldwide is evolving towards tubeless, radial, flat (low aspect ratio of tire cross-section height to width), and lightweight designs.
As an Audi A8 owner, I've noticed that tire specifications vary by year and model. The standard version usually comes with 245/45 R19, but higher-end or newer models may upgrade to 255/40 R20, or even 265/35 R21 with 20-inch wheels. I remember when I first replaced the tires, I chose the Michelin Pilot Sport series, with the size recommended in the vehicle manual—never modify it randomly, or the handling will suffer. Tire pressure is generally maintained around 2.5 bar, and tread wear should be checked before long trips. In short, it affects driving smoothness and fuel efficiency, so don’t overlook this detail. If you own a new A8 L, the specifications are more flexible, so it’s best to confirm with a 4S store to avoid affecting the warranty.
