Greg Weld's 65 Mustang fastback track car

[SSLance]

I can offer this comparison up... Last season I autocrossed on gently used 275/60/16 Hoosier A6s and this season I autocrossed on 200 TW 275/40/17 Falkens. The tire's overall size were almost exactly the same.





When the Falkens were new, they were very close in grip to the gently used A6s but the car was easier to drive on the Falkens. The Falkens talk to you when the grip is starting to go away, the Hoosier's grip just goes away without warning. The car also felt more stable on the Falkens, but that might have a lot to do with the 40 series sidewall vs the 60 series on the Hoosiers.

They used to say that R Comps were good for a 2-3 second advantage on a 50 second autocross run over Street tires but with the advancements in 200 TW tires as of late, they area much closer than that now.
