Updated early Sunday tire results...
STS - Bridgestone 1st & 4th, Toyo 2nd & 3rd, Falken 5th
STS2 - Toyo 1st & 4th, Bridgestone 2nd & 3rd
STX - Toyo 1st, Bridgestone 2nd, 3rd & 4th
STU - Unknown 1st, Bridgestone 2nd, 3rd & 4th
For the record there were more cars with Bridgestone's than Toyo's. My guess is that both brands were primarily of the same size (195/50/15), but there may have been a few B'stone's in the 205/45/16 size too. IMO they seem about equal tires, but when Toyo finally releases the wider 225/45/15 & 22/45/16 sizes they will dominate imo.
STS class '96 Saturn SC-2
