run flats vs. non run flats

My MB GL came with 20" run flats which I thought was fine. But when I replaced them with non run flats 3 years later, the car felt much, much more comfortable, less noise etc. The car felt completely difference in a good way.

I know most BMWs come standard with run flats but looks like I can order the X7 with non run flats with a spare. Also, snow/ice performance was terrible on the run flats compared to the non run flats.

Is there any reason to stay with run flats if I'm not concerned with the occasional flat tire change? I love the look of the 22" rims but not practical for snow driving for skiing.

You can order the standard 21s with NON RunFlats and if you do they throw in a spare tire. If you order run flats, the spare tire is optional.

I ordered the 22's with space saver spare. When it's time for winter I'm just going to change all the tires over to a nice set of all season non run flat. Hopefully they'll be tires available when the time comes because no one even makes a 315/35R22 for the rears. So hopefully it'll be Easier than buying new wheels and snow tires then storing them and transporting them to tire shop to swap ,waiting and then doing it all over again. Did it with my F15, had to buy a kit from Continental with flat repair kit with compressor to keep in the car because there was no room for a spare with 3rd row. So much easier not to deal with winters and a better ride on the 20's I have now.

I ordered mine with 21" non run flats. I don't like run flat tires and much prefer to have a spare.

The BMW reps at the LA Autoshow said, as of right now there are NO All Season Tires available in the size they need for the 22s and they expect the take rate for the 22s in areas where there is snow to be VERY low.

Don't think I'll need snows this year seeing that I won't get the car until March but hopefully by next season there will be some options. 4 choices in 22" on the G07 and maybe 1 or 2 choices on the G05, hopefully equals a new market for tires. If not, I'm reluctantly buying new winter wheels and tires. Gotta have those 22" 755M's though

I am fairly certain bmw will have the 5x112 wheel bolt pattern with a 66.6mm bore which means you can use wheels from Mercedes. So you can find some cheap used Mercedes wheels... for winter

There is a hatch behind row 3 for the spare. If you don't order it you can put stuff in there.

Do you know what the luggage compartment package is and if it reduces storage space at the back storage area.The dealer says it prevents cargo from moving aoound back there.Apparently it is powered and goes up and down.It is a $500 option in Canada.I just looked at the US build your own website for the X7 and there is no listing for it.Maybe it is a standard feature on the X7 in the states

Here is a picture from the BMW Canada website.

I don't know much about that.The x5 does have a retractable cover for the rear cargo area that is powered and goes back into the floor.

BMWBLOG has some info on it,

As I previewed in some of my X5 videos, the new X5 is equipped with an optional Luggage Compartment package which will lower the trunk cover into the load compartment floor with the push of a button. The same package also includes some rubber anti-slip rails on the cargo floor which inflate when the car is in motion to keep the luggage from sliding around.


This video review of the X5 shows how it works.

Nantucket Did you ever figure this out? Is the G05 luggage compartment package (motorized cover and raised rubber floor rails) indeed coming to the X7? haven't heard anything about this, and definitely not in the USA configurators.

From what I've read in the owners book, I believe it is netting for the cargo area. One picture showed the net up behind the 2nd row.

It’s always been an option on the X7 in Canada.I didn’t order it because most of the time i am going to have the 3rd row seats stowed.It works exactly the same way as the X5.

The option was in the ordering guide when i placed my order at my dealer back in December.It has always been on the BMW Canada build your own website.

Any suggestions what brand, model and exact tire size in "non rft" is best to replace the stock 21" A/S rft tires that came on a X7 M50i

TIA

This is what my X7 came with. https://www.tirerack.com/tires/tires...tandard%20Tire

I'm very pleased with their performance as well as the smooth and quiet ride. I will be replacing them with the same tires here soon. I have 29K miles on them now and have another few thousand miles left before they need to be replaced.

motor shouldn't matter, they probably got a bad tire or has a bent wheel.

Mine came with the same tires. Very happy with them thus far. I've only got just under 7k miles on them thus far. But based on the amount of wear in 7k, they look like they will last 25k-30k easily.

Unless something else comes out in the next few years, I suspect I will also replace them with the same when it comes time to replace them. Good thing is costco carries Bridgestone tires, so I can get these replaced at costco.
