Thanks Rob...
The tires are the Goodyear Racing Slicks from Roger Krause (see "
C" style here:
http://www.rogerkrausracing.com/cobra.html).
Here's a photo of the tread:
They are bias ply tires with very stiff sidewalls, even at relatively low air pressures - I ran them around 19 to 21 lbs, depending upon track/ambient air temperature.
The tread is significantly stickier that "regular" street tires, and they have to heat up a bit for they get really sticky. Even cold, when I roll them around, they pick up little rocks and pebbles. And these tires are not "cut" for wet weather driving. In other words, there are no grooves in the tread to channel away water.
Driving on them is kinda like driving on "rubber cement" kinda. These slicks are designed for Road Racing vs. Drag Racing. Drag racing tires require a much softer sidewalls (for flexing) as well as a soft tread for traction, however a tread compound that doesn't require much heating in order to hook up. Road racing tires have very stiff sidewalls.
Hope this helps...
Thanks,
