Porsche has released a list of updated tire recommendations for a variety of old models, stretching all the way back to the 356 B, which debuted in 1959. In all, there are 32 new tire models on the list, covering Porsche's 356, Boxster, 924, 928, 944, 968, and 911 models 964, 993 and 996.
The magic of these tires, apparently, is that they still maintain the look of the originals but use modern materials and manufacturing processes, making them far better for handling than the tires you could get 30, 40, or 50 years ago.
This is the beauty of an automaker that understands the collectibility of its older cars: it takes maintenance and preservation very seriously, even decades after the warranties have expired. Ferrari, Lamborghini, McLaren, and others have divisions dedicated to keeping vintage vehicles in shape; Porsche recently devoted two press releases to a 911 restoration, and offers a variety of new parts like dashboards for long-discontinued models. You don't see this kind of love for an ’89 Toyota Corolla (though now I kind of want to).
The new tires are available now — but if you're serious enough of a collector to own a 356 B, you may have already gotten the call from your Porsche service center.
