Hi no they are not run flats, you can put any make you like on as long as the speed and load rating is correct, have you thought about all season tyres they are good for the cold weather and shift water well. I have the Goodyear all season tyres on mine and they are wearing well 12k and still look hardly worn
After our first two days of snow up here I have had good opportunity to test my new Yokohama "W Drive" winter tyres. Absolutely brilliant, the difference in grip is just amazing under acceleration, braking and cornering in snow and ice. Of course the Yeti Halmex 4x4 gives a great bonus as well.
I can thoroughly recommend these tyres (they are even very quiet on normal dry roads).
