My guess is that any radial performance tire would run rings around Hoosier
TD's. I enjoy racing on the Hoosiers because of their predictable and
controllable slip, but that's not the fast way around a track. With the
camber properly adjusted a good radial has 30 to 90 percent larger contact
patch and slips without losing adhesion.
>From what I hear the big problem with Yoko A048 is that the first heat cycle
is by far the best, so when it's used as a spec tire, the folks with big
bucks go through them like hotcakes and people using them for fifteen or
twenty cycles have a second or so disadvantage. Not likely an issue for
Vintage.

The delivered cost of the Yoko AVS ES100's shaved to 4/32 tread depth by
Tire Rack was $425.82. Hopefully we will have the car on the track next
season and will be able to see how they do. We choose these tires to get
the driving school done and the car sorted out and ourselves. We didn't
want to use up a set of expensive tires for that.
Regarding Tony's comment about all using the same or similar tires, if
that is the route to go then I would think "High Performance" street radials
would be a pretty good choice. It seems to me that they would probably
offer about the same grip as the racing tires from the era that these cars
were raced, which would be in keeping with the spirit of vintage racing.
Just my thoughts.
By the way, the guy at Tire Rack, who races himself, thought the Yoko's
would work pretty good but not being soft compound wouldn't have the
ultimate grip as the Hoosiers. But he thought they'd stand up okay.
