17" Run Flats for E81

[philh]

I need 3 new tyres for my E81 118d. Two on the rear and one on the front. I also want to stick with Run Flats so please no suggestions of swapping to non-RFT.

225/45 R17 Rear: Looks like the reviews suggest ContiSportContact 5 SSR and the price seems to be reasonable on these. Anyone have any views or alternative suggestions? Goodyear, Bridgestone?

205/50 R17 Front: ContiSportContact 5 SSR are not available in this size. I also only need one tyre. The tyre I'm keeping is a Goodyear Eagle NCT5 RunonFlat. Should I get the same again or something else? Appreciate going for something else would mean mixing brands on the front axle.

All help & advice appreciated please.
