Is 1/2" leaf spring relocation worth the trouble?

Tire sizing can be funny too! Some 255's and 275's are very close in actual measured specs, I know there used to be some 305's that weren't all that much bigger than 295's. So there are definitely tires out there where the difference in the advertised size and the difference in the actual size aren't the same thing. And that's even comparing the "measured" specs, not accounting for a tire that's been mounted on a wheel that's smaller than the measuring wheel.

I though the same thing, but could find any specs on the G-Force Rival it looks like he was running at the photoshoot.

This picture does show 315/30R18 on the sidewall, so maybe just his wheels are different for the track.
