fwiw, here in australia, we are almost spoiled for choice . with race
tyres . we have lots of relatively new-comer asian made race tyres, some of
which are very good for the $. BUT, few are available in much less than
205/50/15 size, so 13" is =C3=BCnusual", if thats what you are asking about=
.
they are all radial construction
if you are looking to move away from Hoosiers (which are relatively
uncommon here) , look into Nankang and Hankook, which both appear to be
comparable to many established race tyres and often for 50% of the price.
