I have 22inch wheels on my X5 which is on Adaptive M Suspension. It rides great. No complaint here at all. Adaptive DHP would be perfectly fine on 22s

Have the 22" on the X5 40i. Can't speak to the M50, but the 22s make the car's handling feel ungainly/top heavy and do compromise the ride. They look too large and goofy as well.

But I haven't driven the X5 with the 21" wheels, maybe the handling/ride isn't too different.

My wife has had a flat approximately once every two years - I can remember about 5 instances in the last 10 years. Not sure if we're just unlucky. Given her history, run-flats are a no brainer.

As for changing tires, I'd guess that less than 25% of all drivers in the US can change a flat tire. Of course, the members of this forum are not your typical drivers.

P.S. - In addition to having run-flats on my X5, I do keep a spare tire, too.

Let's not talk about road quality for a moment as it has a lot to do with many factors - rim size, suspension, windows, car's generation etc. However, from a safety perspective, are run flats significantly better than non run flats?

From a safety perspective regarding run flats vs non-run flats... I think it depends on where you live and where you drive the vehicle.

I had run flats on my two 2017 BMWs. I live in the Houston area and decided against run flats for my new BMWs. I figure there are plenty of rollbacks to rescue us should a tire go flat. I also ordered the X5 with a spare.

My new M5... no space for a spare. I wouldn't order an M5 with run flats anyways. Doesn't make sense.

To be fair, I've had one flat in the past 10 years. That contributed to our average.

That is all about not having DHP. I have had loaner G05 X5's from base level on up. Last 19" wheels on a base X5 felt so top heavy, I cant believe its the same vehicle I use to own with DHP. It wallows going down the highway in a strait line.

I agree. DHP makes a big difference and should be a must have on the X5. Makes a big difference, along with the performance brakes - IMHO
