CJ. It's only what I seen with mine but I noticed a big difference in how the tire "wore" going from 10s to 12s. I run between 17 and 20 psi. With the 10s about an inch of tire on both sides was not getting "wear". Once I went to 12" rims even wear/stickiness post run right across the tire all the way to the sidewall.
Looking back I don't think I was using anymore tire on the track with the 10.5 tires then the 9" tires when mounted on 10" rims
That's on a SS/JA car that 60s in the low 1.30s. Your results may vary of course.

Good luck!
