Caesy, when you say slick, by them self could shave .5 imo

What size the slicks?

The 12.59 @ 8 psi might sound good, but the truck feels at mid pull at the end.

My target is with this street set up low 12, 12.2 will be nice, but I just upgraded my brakes, and they say nothing under 20" rims, so now I have less options.

Some said 27" diameter was the best
