2002 Silverado - Correcting for tire size?

I don't do much GM stuff, so maybe I'm just missing it somewhere... but how do you correct for a different tire size?

In my VCM Editor, I went to the speedo tab, and all I see is a "trans revs per mile" option. There is no tire revs per mile, or tire size option in there.

Click the edit tab, then click the gear tire wizard. Change the tire size and input the same gear ratio and have it auto scale the transmission for you.
