For my Lola, Hoosiers have funky sizes (too tall), so the Avons are the best fit. Dunlop also publish a size that would fit but I'm not sure if they're ever produced/stocked. Avons are also known to be high quality (long lasting, good concentricity)
It SEEMS like Avon would have an OK market size since they basically own vintage racing, at least for the canam/endurance and formula side. I'd rather see them raise prices than stop making tires completely!
Anyone know how long bias ply slicks stay good for "on the shelf"? I may order a spare set to mitigate some risk here. But it may be 5 years before I need to mount them.
