vibrations is a consequence of your tyres not being balanced. This
shimmy or vibration normally occurs at speeds of over 30 mph the
vibration will become more intense as the speed increases so at 60 mph
and above it will feel like the whole car is shaking. In most cases if
you feel the vibration and shaking on the steering then it?s your front
wheels that need balancing and for those that feel it on their rear then
it?s the rear wheels that need balancing.
Keeping you wheel balanced not only extends the life of
your tyres and suspension it also makes the driving experience a lot
more comfortable and easy.
The reason why these vibrations occur and why you need
wheel balancing is not so apparent although every tyre looks perfectly
round and rigid. There are actually there are heavy spots that cause
balance problems in the wheel.
the wheels are not balanced, driving can be very annoying and this
imbalance has a knock on effect on other components including suspension
and tyres. Tyres that are not balanced could wear unevanvley and may
need repalciing prematurely..
The proper procedure of installing a new tyre is to
balance the wheel before installing it on the vehicle. This is done on a
computerised balancing machine similar to the one in the picture on the
left. The machine spins the wheel and is able to calculate where the
imbalances are, these are the heavy spots are. It then calculates the
amount and location to place the weight. Wheel balancing weights are
either clipped onto the edge of the rim or stuck on the rim.
Not all problems to do with steering vibrations are
because of an imbalance. You will also experience similar faults if the
tyre has gone of shape whereby the structure has been damaged. If one of
your rims has been buckled, etc. The best course of actions is to have
the wheels and tyres checked immediately as it could be a very serious
issue. Often wheel balancing weights can drop off which will mean the
wheel is no longer in balance if this is the case it can easily be
corrected by re-balancing and adding new weights.
