Tyre Rotation
Tyre
wear rates differ depending on the axle on which the tyres
are fitted and whether the vehicle is front or rear wheel
drive. To extend the life of your tyres it is advisable to
change tyre positions on a regular basis. Different tyre manufacturers
may recommend different rotation periods, ranging from 2-6,000
miles. It is advisable to switch tyres from left to right
periodically as well as from the back to the front of the
vehicle.Certain high performance tyres are position specific
and should not be rotated. If in doubt, contact a specialist
tyre dealer.
There is some dispute over the fitting of a pair of new
tyres to a car. Simple logic suggests that the car needs most
traction at the drive axle. In some cases that would be true,
for instance if you were constantly driving in muddy conditions
and needed the grip to keep you moving. However, irrespective
of the vehicle, front or rear wheel drive, or even 4x4, the
typical vehicle is designed to understeer in skid conditions.
That is, it ploughs forwards.Generally, backing off the power
and the brakes will recover the vehicle from the skid, though
not always.
By putting the grippier tyres on a front wheel drive car,
it increases grip at the front, but equally increases the
difference in traction/grip between the front and the rear
tyres, so the rear tyres lose grip early and as a consequence
the car is at risk of going into oversteer. For the average
motorist oversteer usually means ending up rear end first
into the field (if they are lucky). That argument can also
apply to rear wheel drive vehicles, it is not about getting
the power down on the tarmac, it is about keeping the rear
end of the car in contact with the road.
With four wheel drive vehicles, rotation of tyres is much
more important and all four tyres, ideally, should be replaced
at the same time. So, location should not be an issue. If
it is, the same rule applies, newer tyres to the rear.
