Mako any word yet on recalibrating your speedo and odo? Its not too crazy of a change...since the distance your speedo/odo is going off of is wheel/tire circumference. And as everyone knows circumference is 2*pi*r. r=(r-.25in). So if you do all the math...and I did...you get a 2% change in circumference and thus a 2% change in velocity and distance traveled. Its up to you if you want to fix it. But you'll be going slower and lass far than your instruments will indicate.
