Run flats
I've been running non run flats on the front and run flats on the rear for about 6 months/7000 miles no problem. Rears are finally getting swapped out in a couple of weeks

No no no never mix runflats with normal tyres, occasionally some do but it affects the handling and if the worst should happen I'm sure your insurance would take a dim view.

Run flats
Handling will be all over the place. Run flats are a very stiff tyre so mixing that with a softer compound non run flat the car will feel out of balance

I ran non runflats on the front and runflats on the rear on my last car for quite a while. It was fine. didn't affect handing.

This is an extract from National Tyres.
Mixing Conventional Tyres with Run Flat Tyres
As a general rule of thumb, you should avoid mixing different tyre types on a vehicle. This is also true of combining conventional and run flat tyres on a car – as their handling characteristics may differ, they should not be mixed on a vehicle.
Makes sense to me

This is true but you’d never mix ‘cross-ply and radial’ tyres would youNick9one1 wrote: ↑Tue Feb 20, 2018 6:24 pmBut also take into account this is written by a company that sells tyres.GBZ4 wrote: ↑Tue Feb 20, 2018 6:16 pmThis is an extract from National Tyres.

Ran standard tyres on the front of my e90 with run flats on the back and although not ideal, It ran fine. Ditched the run flats as soon as they were 2.5 mm. I don't see that they could affect the car too much as essentially they just have a slightly stiffer sidewall. Unless of course you are ragging it around a track etc.

Run flats
If you drove a modern car all times at the speed limits in the uk i would find it hard to believe that braking , cornering or safety would be hampered running mixed runflat / non runflat paired on different axles .
Yes of course it will always be better to run 4 of the same year , depth , make + model tyres but its far more sketchy running the wrong pressures .
Worn wiper blades through dark winter months is probably more dangerous
