What's the circumference on the Goodyear radials? The Hoosier 9x30 radials I used to run were available in both 92.5" and 94" (I ran the 92.5").
Your 60-ft seems "soft" to me, although I'm not sure what to suggest given what you've described so far.
Our cars are pretty comparable in performance (compared to my last running combination), but mine was pulling low 1.5s when it ran 11.0s at 121 and in the 1.45-1.47 range when it dipped into the 10.5s at 126.
