:question: does anyone know what tires can be used on the stock 512 bb 15"wheels?
i have a 1979bb
i have seen bfg tires, but was told that the wheels are metric and i should use the old design michelins. (hard compound)
I don't understand the reasoning why some European manufacturers went with metric tires in the first place. The TRX was a high-performance rated tire and I suppose it met Ferrari's needs at the time. I think Mercedes used it as well. They may have thought it would take-off in popularity and were trying to get ahead of everyone else. Whatever the case, it was a big marketing flop...
The only difference is the wheel rim diameter (which Ferrari used 390 and 415mm sizes on their cars). I don't think there are any other brands that make them, so your only alternative is to purchase an inch-sized wheel.
For what it's worth: While living in France I had a new set of 15" Michelin installed on my US Mercedes. The tires had metric size on one side and US on the other but the seal area was much wider than the US tires removed. They all ways looked like they were poping of the rims.
