Run Flat Tyres
The main advantage of the run flat tyre is that it
is able to continue to work at pressures which would
render an ordinary tyre flat. The tyre utilises self
supporting technology which means it is able to support
the weight of the vehicle with no air at all. If you
look at a cut through slice of a run flat tyre you
will notice that the tyre walls are much thicker at
the base of the tyre.
All modern vehicles fitted with run flat tyres have
an electronic tyre pressure measuring system to tell
you when the tyre is flat. When you experience a puncture
you normally have about 50 miles of driving time at
a reduced speed which will enable you to take the
tyre to be fixed. Cars with run flat tyres do not
have a spare wheel in the boot.
Advantages: safety, money saved on spare wheel,
more room in boot
Disadvantages: sometimes harsh ride. Especially
with very low profile tyres. Not as easily repaired
as conventional tyres.
