I want to change a 6620 from 28L x 26 to 24.5 x 32 tires. Do I have to change the rear tires also we currently have 11.00
x 16 on the rear ?? If we don't change the rear tires will the front of the combine set up too high in the front and cause crop loss out the rear? Will this change cause the digital readout for speed to read a slower speed than we are actually traveling?
