Test Warns Against Retro-Fitting Run-Flats
The results of a recent Auto Express test show that motorists with cars set up for and fitted with run-flat tyres must not replace them with standard tyres. The test, carried out in summer 2006, demonstrated that fitting a standard tyre to a car which was designed and set-up for run-flat tyres can cause a loss of performance and ultimately a reduction in the safety of a vehicle. The results published 11 October show that using a standard tyre with the same tread pattern can severely increase braking distances and reduce overall wet and dry handling.
