FW TECHNICAL TIPS TYRE CHANGES AND WHEEL BALANCING
Vmaxers
In a previous article I indicated that I would
advise when I changed my rear 180/55 X 17" Michelin pilot road
tyre.With 2 weeks left to the Vmax rally I decided to retire the
tyre with 1.5 mm of tread left and fit a Michelin pilot sport.The
pilot road up to that stage gave 7400 miles(11840 km ).Although it
would have gone way beyond 12000 km I needed to change in
anticipation of the 2000 km journey to the rally.
TYRE CHANGING
As can be seen from the pictures in step 1 to
5 the tyre changing is really reasonably simple and easy.The idea of
cutting the tyre off the wheel is not mine ,and although I have
never seen it done before I heard about it from a non Vmaxing biker
,Dave Leach. I did the tyre change without anyone showing me and
therefore I believe it is possible for anyone to do.It suggested
that the DOT mark on the tyre be lined up with the valve since the
valve is normally the heaviest part of the wheel and the DOT mark on
the tyre is the lightest.
WHEEL BALANCING
An unbalanced wheel will always come to rest
with the heaviest part coming to rest at the bottom(6 o clock).This
is due to gravity.
Mark the 12 o clock position with chalk as
this is the lightest position.
Add weights to the 12 o clock position and do
so until the wheel comes to rest at 3 or 9 o clock.It is then
balanced.
It is really as simple as that.
