You know you can just jack the rear of the truck up, put it in neutral, mark a spot on the pinion & a spot on one of the rear tires and just spin the tire and count the revolutions of the tire vs the pinion and you’ve got the gear ratio. 2-3/4=2.73, 3’ish=3.08, 3-1/4=3.27, 3-1/2=3.42, 3-3/4=3.73. You get the picture.

I tried that and it came out to 1-3/4... I don't think that's right.

I'd go with the 28" tall tire.

So you guys are thinking 28" all the way around is the ticket? That would make things easy for sure. We just bought a tach dash, I'd like to drive the truck with it installed to see what we are actually taching at 55, 65, and 70. If we're going to take this thing on the highway it needs to be able to keep up!
