I have a 2011 X5 3.o
Bought it from my sister in law with 40,000 kms.
She burned off two sets of Dunlop run flats.
My wife killed an additional two sets. At $2ooo/set
At 90,000 kms it was time to replace again. In my research?
I chose Continetal dsw's. Front tires are 7 pounds lighter, rears are 8 pounds lighter than a dunlop run flat. The car drives, in my opinion, much nicer with 32 lbs of less unsprung weight. A no air run flat tire can get you 50 miles without air. For me 50 miles in the middle of no where makes no difference to me. The corner gas station in the town of 95 people will not stock a 315/35/20 nor a 275/40/20. So I'm still scuppered.
My car does not come with a spare, nor does it have a jack and tools.
I put a jack and tools in there, a plug kit, tire repair inflation goo, battery jumper pack with air compressor.
Me? I like the DSW's and will risk runflat 50 mile safety distance. To note, I also run snow tires, and leave an off season tire at the cottage.... so, I am only 1/2 a trip away from a spare tire.
DSW's now have two full summers on them, and going into a third with great tread left.
