There's not much difference in diameter, but there's not much difference between 3.55 and 3.73. I've run
30.1 on 3.55 (255/70/16)
31.6 on 3.55 (265/70/17)
31.6 on 3.75 (265/70/17)
31.9 on 3.75 (275/55/20)
I would run any tire with a diameter less than 31" on 3.55 and any tire with a diameter larger than 31" on 3.73.
