Two Piece Wheels
Two piece wheels are disc wheels with removable
rims. The illustrations on the following pages show
the rim and disc positions for the various tread
widths. When the rims are reversed to change the
tread width, install the right hand tyre and rim on the
left disc and the left tyre and rim on the right disc to
make sure that the tread pattern is in the correct
direction for maximum traction as shown by the
arrow on the tyre.
Use the chart below as a guide to establish the
minimum tread width possible for the tyres
fitted to your tractor.
