Disc Wheels
WARNING! Use the correct components and
tools when working on wheels. Grooves in the
wheel disc or other damage to the disc can
weaken the wheel and cause it to eventually
come off. This could cause you to lose control of
your vehicle, and may result in an injury accident.
The end of the wheel wrench must be smooth. Burrs on the
end of the wrench can tear grooves in the disc. These
grooves may lead to cracks in the disc, and can cause it to
fail.
