find the type of 9.00r20 you have and
get the "Static Loaded Radius"
need that to do some rough calculations
20in tires put a tremendous strain on the
running gear as you have increased the radius
by 2 inchs 8 to 10 from the center of the hub
to the heavy part of the wheel and then by
about 2.2 inch to the mass of the belt/tread
of the tire and everything is base on the square of the radius - a lot more energy
required to start or stop the assembly rotating . you would also have to take into
account the difference in mass between the
standard 9.00x16 and the 9.00r20 tire/tube
wheel assembly
