Tires that didn't make it onto the list:
74
Hankook Ventus R-S4295/40R1810-11.5300
Endurance 200tw
NoWidely regarded as the endurance 200tw standard. Wears well and retains performance with heat & cycles. No Viper sizes.
75
Pilot Sport 4S is available in Gen 5 sizes, including ACR. But it's 300tw and doesn't really hold up to track use
76
V730 only has 275/35R18, 275/35R19, 305/30R19
77
78
Notes for 315s:
79
Good value: Kumho V730
80
Fastest: A052, RS-71RS, CR-S
81
Best wear/consistency: RS4, ECF*
82
83
ECF wears pretty well, but is poor at communicating longitudinal to lateral grip transitions. esp on Porsche, Miata, etc where trail braking and pivoting (doing multiple things at once) is needed, it's a tough tire to drive.
