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.

I would also add. Most OEM dealers will not repair a run flat tire, they will only recommend replacement. And if the tread difference is great, recommend tire replaced in pairs.
If you have a propensity for punctures? Choose carefully.
Most tire stores would consider a repair of a run flat.

Got my Pirelli Scorpion Verde All Season Run Flat's installed today. Like them so far. Doesn't seem to ride any harsher than the regular tires I replaced. Also wanders less.

A few hours of ownership isn't worth a flip for a review so I will post back as I clock up some miles on them.

my exact thoughts and set up I have the continental tires Extreme Contact dws06 on the front and rear and really like them. The X5 handles great with them on.

Also keep in mind that runflats are stiffer, but the pressure specification for our x5 is too low. If you run 38 psi on normal tires they will flex less than the stupid low spec pressure.
My snow tires at 40psi feel great handing no mush, yet don't transmit the bumps as harshly as my normal set which are still run flats.

Glad it *is* back on track.

I do want to comment that tire alignment can be a very large factor in tire LIFE.

Some will opine that 'wear is even, so alignment is good'. This can be a bad assumption.

Also, people (some people) seem to think that 'alignment' is a binary thing: "took it to the dealer, they say it is aligned".

There is a broad range in the BMW spec, and if you set it in the middle you will get less then optimal mileage. Significantly. Like 1/2 to 2/3s. And set at the wrong end of the spec, you can see as low as 20%. (all these examples would be 'in spec')

Which brings us to the last false argument- ya want lots of toe to get turn in. or BMWs are set aggressively to get that BMW handling, ya need to pay to play.

In summary: When making decisions about tire LIFE, dont ignore your alignments.



And agree on the pressures, I tend to run my tires a bit higher

At $2,000 a set you may want to check TireRack or similar sites. The most I've ever paid was $1,450 including installation. Good luck.

I'm canada Eh. Tire rack does ship here, but with duty and shipping???
It really is $2k cdn here. No matter the source.

Agreed 100%!! Too many ignore alignment and/or don't have it checked once a year. Seem way too many a tire prematurely worn out because the alignment was off.

I just killed both of my RF Bridgestones HP Duelers 275 40 20 by driving on highway from Toronto to Florida and back over 5k kms. Both bold on the outside with drivers more so. Shocked. Did alignment at Midas and pumped to 38psi befire the trip. Went back to Midas today to ask for my data but surely they dont store it. I found another shop with "German" alignment machine and made an appointment there - C$180 for alignment - crazy but hope they do it right. I will need new tires though.

I am looking for replacement Summer tires 275 and 315 for 20 rims as of last night when I arrived home and reading on forums that changing just the fronts and keeping used rears is not a good idea. In this case a non-RF came to mind as a quieter and more reliable/durable option. Came across Continental Extreme Contact Sport non RF. This is vs SSRs RFs or Bridgestone HP Dueler RFs. Dont want ti change tires twice per Summer.
