A large group of us race Porsche 356 and 912's with Rocky Mountain Vintage
Racing (RMVR) and have been looking for a suitable race tire. Our specs
require a DOT approved 60 series or greater tire in 195/60/15 or 205/60/15
size. No one makes these any more; Hoosier, Yokohama, BFG, Kumho, Avon,
Goodyear, etc. Most only make 15" tires in 50 series. My search has come down
to two tires: Hoosier Vintage TD 5:50-15 or Goodyear GS-CS-1 in 215/60/15. I
also considered the Hoosier R3SO3 in 215/60/15 but the section width of 9.0"
was too great and I am also worried about the section width of 8.5" of the
GS-CS-1 tire.
What is your experience with each of these tires in terms of fit, durability,
handling, availability, etc. ? All help would be greatly appreciated.
