I am going to put on a RE 4.5" lift, and am unclear as to what size tire to use, I was thinking either 32" or 33". My question is if I use 33" tires, am I going to need to re-gear and if so, to what ratio? I am new to this hobby and want to make sure my rig is done right. It is my DD and needs to function both on and off-road. Thanks to all.
