Run-flat tyres have rigid sidewalls, allowing motorists to continue driving even with no air pressure in the tyres. In the event of a puncture, this means drivers can continue to a garage for a replacement tyre.
AA Tyre Fit says the take-up of run-flats on new cars where they are offered as an option is 'negligible' and only where they are supplied on some luxury cars as standard are they finding their way on to the road.
General manager David Goodyear said: 'Where run-flats have been fitted as original equipment on more expensive cars, then buyers seem to be pleased to have them and, when it comes to replacement, willing to replace like-for-like. '
However, where run-flats are offered as an option by manufacturers, buyers are not interested. It seems they are not willing to pay a price premium for them in the showroom and that they are also nervous of what the replacement cost may be.'
