I have a Case W20B loader that is just a little short when loading a dump truck with side extensions. It currently has 17.5-25 tires on it. If I go to 20.5-25 tires will that help with the height issue? Will it cause any other issues? Will I still be able to dig, or will I be too far off of the ground? Will 20.5 tires fit on my rims OK? Will I lose too much torque due to "gearing" change?
