Tires and tubes are balanced as individual units and marked
at time of manufacture. The tire balance mark is a red dot.
The tube balance mark is a yellow stripe on the base of the
tube. Always assemble tire and tube with marks aligned.

valve stem adjacent to tire balance red dot.
D. Install tire and tube on the wheel half containing the valve stem hole and then the
opposite.

nuts evenly and torque to 150 inch-pounds.
Uneven or improper torque may cause a bolt or wheel
failure. Inflate tire until tire beads are sealed, remove
schrader valve core, and allow tube to completely deflate.
