Previously, when they tried to go metric in rim height, they used 360mm and 380mm. A famous name was the Michelin TRX tire.
These are very common (or were) on early to Mid-1980s Ford Mustangs, Peugeot 505s, Lotus Esprits, Ferrari 308s, and other cars in that area that were considered high performance. Finding 360mm TRX type tires nowadays is pretty hard and when you do find them, they are very expensive.
