Why 3.91/4.10 Gears make the best short term expressway gears!

i just added Nitto DR that are 28" tall, before i had 3.55 with bfg radial t/a's 25.5" tall they would spin with 1/4 throttle, but with the new tire the 3.55 are kind of lame, so i'm thinking 4.10, still ok on highway and much better light to light since i can hook.
