I have had the 6th blow out
I have had the 6th blow out over a period of 4/5 years with RUNFLAT tyres
Included are 2 cracked alloy wheels which had to be replaced.
My advice is to go nowhere near RUNFLAT tyres
BMW do not wish to know
Tyre manufacturers and local authorities ditto.
Runflat tyres on any sunken drain cover and irregular surfaces as you go over them on badly maintained roadways in UK are so solid there is no absortion effect as on NORMAL tyres.FULL of AIR and very flexible
I think BMW did not do there homework on runfalts properly.
DO NO GO. THERE. BEWARE.
