No. I also installed lowering links so mine sits lower than factory setting at lowest level.
I removed the links for winter but at load level height, it looks like the vehicle it’s resting on the tires ONLY when parked. Sport mode and comfort mode are also lower than factory settings. I’ve ran this set up for a couple years so I can’t give you a completely accurate answer because I run the custom set up.

Thanks for all the info man! Looking at options now.

I too have the staggered 22's and can't run summers year round. I was nosing around on Tire Rack and I've seen people putting these on their X5M's, X5's, X6M's and X6s.

I have the 21 square setup NON run flats on my 2020 X7. I wouldn't have it any other way due to the slim pickings with 22 and 23" tires. Not to mention the potential extra damage to both wheels and tires with the lower profile side walls on the 22 and 23 inch tires. Curb rash and pot holes can wreck havoc on larger tires and wheels.

Just my two cents worth of course.

I’ve got 21 square all around, also. Mine are Bridget stone runflats and that sucker rides like a sofa on wheels. Do you think the non runflats make it significantly better? Because if so, that’s got to be insane. Like riding on air

I had a loaner X7 once when mine was in for service. It had run flat tires. I could tell the difference within 20 seconds of driving on those run flats that they were run flats. No comparison between run flat and non run flat tires in my opinion. Non run flat tires are the only option, if available, in my personal opinion.

I will never buy run flat tires or spec any new car with run flat tires unless there is no other option.

I think our X7 actually has a spare. If it does, I’ll switch when we eat through these.

325 is out of spec for the rear width by 10mm. i asked tire rack, and while they could not officially endorse it, they knew of quite a few people running 325/35/22 on a 10.5 rim without issues.

the other option is 285 all around. its in spec for the front rims at 9.5 and rear at 10.5. i believe others have had good luck with 285/45/22 for a little more cushion and selection.

I have to agree with 285/45 for more cushion. It will also increase the circumference, which will have lower revs/mile, which has the effect of a numerically lower differential ratio. You will show slightly lower MPH, so you put miles on the odometer more slowly. The lower effective drive ratio should actually give you slightly better MPG.
Your mileage may vary...

The first tire would work as it is available in the staggered 22” size.

The second tire is not available in 315/35/22 nor in 285/40/22 if you wanted to run a square setup. Which is a shame because I would definitely use them otherwise even though they’re not run flat.

Bumping this thread, seems there are interesting options if you bump the diameter up just a bit to 285/325:

I would go 285/45R22. This will give you a slightly more cushioing sidewall and a better ride.

If you want to go from 22" to 21" for wheel and tire, what options do you have?

I researched bmw parts, and they list the 21 inch wheels and winter tires. Do I have to go with BMW a set? I go with an aftermarket set will it void the warranty if something happens?

Any 21 OE set alternatives?

I had an aftermarket 22 staggered set on my ‘21 X7 with winter tires, serviced it many times and nobody ever brought up voiding warranty at the dealership. I plan on using the same winter wheels/tires on my ‘24 X7 M60i when it delivers too

The OEM tire size is going to be the determining factor, not whether they are runflats.

They're not going to just "void your warranty" when they see the different size tires. They're not tracking tire sizes on every car that comes in for service. If you have an issue with the AWD system or transmission and bring your car in to get it fixed under warranty, BMW may check the tire size before fixing your issue. If your have non-OEM tires, BMW can refuse to cover the issue under warranty.

I see. I chose everything with the tire rack “expert” and they confirmed it is compatible with my X7, but they can still refuse to fix an issue if the OEM wheels are not on the car?

My car came with 22s and my winter set is 22 as well, just an fyi

Great news for 22” wheels. Continental now has an All Season. 315/35/22 DWS 06 Plus. Great tire
And better yet it’s not a run flat

[Takei426]

That's a good news for everyone.

On https://continentaltire.com/tires/ex...act-dws06-plus it does look like there is a:
Front: 275/40/22
Rear: 315/35/22

However the Continental website indicates these tires are not compatible with the X7 M50i.

On Tire Rack:
- I think these 275/40/22's would be the right tire for the fronts
- I think these 315/35/22's would be the right tire for the rears:

I had to input these sizes manually into Tire Rack to get them to show, they don't have this tire mapping onto compatible with X7's yet. Can someone who knows more about this confirm these would be the correct tires and fit the vehicle?

I contacted Continential directly to see why they don't believe these tires are compatible with the X7 and they responded:

While we offer the DWS06 Plus in the same size and exceeds the load index, 275/40R22 108W XL, the speed rating is W. Your vehicle requires a 275/40R22 107Y XL, so the ExtremeContact DWS06 Plus is not a suitable fitment for your vehicle.

The tires speed rating is not just the maximum rated speed for the tire, it also impacts the performance and handling expectation set by the vehicle manufacture. For that reason, we do not recommend using a tire with a lower speed rating.

The rears for this line of tires do appear to be Y speed-rated, but the fronts appear to be W speed-rated.

Does anyone have any input/thoughts regarding this speed rating on the front tires being "W" speed-rated versus the required "Y"? They claim it impacts not just maximum speed but all speeds... is that true? I don't drive my vehicle over 168mph (which is the W speed rating), so max speed isn't an issue, but any thoughts on the "impacts the performance and handling expectation set by the vehicle manufacture" comment? Would putting a Y-speed rated tire on void the vehicle's warranty, or impact an insurance claim/accident situation (assuming you were not going over the 168mph "W-rated" speed in the accident/insurance situation)?

Short answer to your concerns, you'll be 100% fine.

The correct size matters first and the load rating second. Both matter much more than the speed rating, which in this case (as you pointed out) is way more than sufficient at 168mph.

This. You shouldn't be concerned about speed rating unless you will be sustaining a very high rate speed for a great distance over quite a length of time.

I've had the DWS06+ installed on my M50i for a few weeks now -- no issues. TireRack rep had no problem selling these, and Discount Tire had no problem installing them. I highly recommend these if you want to go away from RFT, and stay with factory size. Get a spare if you don't have one already.
