[Bob Adams]

The Street TD's are the same compound/design as the Vintage TD's, but they
are molded without any tread save for a couple grooves that run around the
circumference of the tire. When asked if Hoosier would make a 205/60/15
Street TD they basically said that they "weren't interested".
The Speedsters are ok tires, but the fastest SVRA Group 3 legal tire they
are not. We pull pressure and temperatures after EVERY session and have
tried everything as far as pressures go. As for alignment, keep in mind that
your car is a couple hundred lbs lighter than the production bodied cars
(SVRA min. weight is 1950# for the
TR3-4's). Tire for tire, they are not on the same speed level as the
Street TD's and
the other decent radials. It also doesn't help that the fast radials are
manufactured and are vintage legal in 205/55/14 where the 15" cars are stuck
with 205/60 (that's a .4" difference in sidewall !). This isn't an issue for
most, but when you are racing for the podium in 50 car fields it is.
