I am in the process of ordering a 2023 X7, really love to have the black 22 inch 755M with M sport Pro black Grill & Trims. But there is no A/S option for 315/35/r22 tires. I need All season tires because I will drive in light snows in PA(will stay home during heavy snows). And I don't want to deal with the hassles of 2 sets of tires/rims for summer and winter.

I saw another member posting installing 285/40/22 square A/S set up. If I want to run this set up, do I need to replace the rear rim?

I believe the OEM set up for 22s are 275/40/22 and 315/35/22.

you can run 275/40/22 on front and rear.
Wheels, fronts are 22X 9.5 and rears are 22X 10.5
the rim width range for most 275/40/22 is 9-11"

you could also run 285/40/22 front and rear for a little less stretch on the rear tire, the width range for most 285/40/22s is 9.5-11

vredstein makes an all weather tire, severe service snow rated in that size.

i actually just added the 755Ms to my order, going with full on snows on 20" rims

[Bruce322]

Thank you for the professional reply. So no need to change the rear rims, and seems there are many 285/40/22 A/S tire options.

Will this affect the drivetrain warranty? since we are not running the OEM size and can they argue the wrong size tires caused problems?

should it? no, the stock sizes are the same diameter front to rear (the aspect ratio drops for the wider rear, so the sidewall height is the same). but in theory they could. there are still good options for 275 tires and the front and rear rims are within spec for that width. you'll have a little more stretch in the rear.


the drivetrain would be unaffected since all 4 tires will have the same rolling diameter (rim width does not affect the diameter). mismatched tires either side to side or front to rear can damage the transfer case or diffs (if the diameters dont match, something needs to "absorb" the discrepancy, and its either the differentials or the transfer case), but all the tires we are talking about have the same diameter.

one thing to be careful of is that a service center might try to rotate the tires front to rear. that could cause rubbing problems up front as im not sure the front fenderwells have the space for the rear rim width.

Thanks for the explanation again.

I usually do tire changes at dealers too, the service rep was willing to work with this kind of request for another car earlier. I will probably do 285/40/22 square set up. so increase from 275 to 285 for front, and decrease from 315 to 285 for rear.

I put a deposit to reserve the 1st 2023 x7 allocation back in February. Hope it will arrive soon!

my CA is saying end of august or early sept. i'm the first in the order bank at my dealer. i think its a plausible timeline, i had an order from SC come in within 12 days from the time it went into production, granted that order went into prod the evening after i placed it, and it was put on a trailer very soon after it finished, so all the stars were aligned.

I noticed Michelin makes some pilot sport A/S4 tires in 275 40r22 for front and 295 40r22 for the rears. Would this work better than the square setup?

there's size difference.

275/40/22 is 30.7" in diameter, 678 revs per mile
295/40/22 is 31.3" in diameter, 665 revs per mile

2% difference. the front will be turning faster than the rear. this might confuse dsc as well as it will think the front is slipping to a degree.

1% is usually quoted as the acceptable limit for X-Drive.

some of the M cars do run a difference between front and rear, but they are programmed to handle the difference.

I run Vredestein winter tires on my 22” factory 755M wheels in 285/40/22 and they seem to work fine and the rears don’t look stretched to me. Like the post above, I would try to keep the overall diameter of the tire close to the same.

[JoeyDDD0919]

Was searching for wheels and came across someone selling a set of 21" OEM Range Rover Land Rover L405 Wheels W/ Hankook 295/40ZR21 Set for $2500.

So attempted.

But man, that rims don't look close to fit an X7...

Also came across a set of Bentley Bentayga wheels. Those look nicer though..

Anyone ever put another brand wheels to their car?

@patgilm how long have you been on these tires and how's the ride quality been? is there a significant drop from the stock summers?

First thing you need to check out is if the bolt pattern and offset are the same that bmw uses.

You have some leeway on offset but obviously the bolt pattern has to match exactly.

I am getting nitto NT420V installed Monday. 285/40-22 and 325/35-22. Slightly taller than stock, but same height/circumference front and rear. I went with them because they are more reasonably priced, available now and have a better Treadwear rating. The stock rear 315/35-22 has been on backorder for a while.

I also looked at this tire as my wifes tires are coming to an end and i love Michelin Pilot Sports. I think 285 40 22 front with 295 40 22 rears is what I will go with. I wish the pilot sports came in 325 35 22 and then i wouldnt have any potentials issues (x drive diamter tolerance is 1%) If not, 285 40 22 square will be what I end up with.

Anyone run the slightly staggered 285 40 22 front and 295 40 22 rear setup?

pilot sport 4s is avail in 325/35/22
https://www.tirerack.com/tires/TireS...erformance=ALL

only caveat is, technically 325 is outside of approved spec for a 10.5.
although 315 is ok... not sure 10mm is really a big deal or not. i will probably go with that setup if i decide to go with non runflats.

Yea, i saw those but im going for something with better treadwear and Pilot Sports A/S 4 seems to almost double treadlife and comes with 45k tread guarantee

it's 22.5K or none for the treadwear guarantee-- they will ask for rotation proof and depending on how they inteperet it. the 10.5 rims wont fit in front without hitting the strut.
based on the wording, 285 square would probably be void, 285F 295R would have 22.5K miles

from the michelin warranty booklet:
Treadwear
If the tire treadwear does not reach its mileage warranty a pro rata
replacement of the tire may be available under this warranty. For the
mileage warranty associated with a specific tire, please see your Michelin
tire retailer or visit www.michelinman.com/promise.
In order to maintain the treadwear warranty on your tires, the tires must be
rotated every 6,000 to 8,000 miles (10,000 -12,000 km), or as recommended
by the vehicle manufacturer, whichever rotation period is less. Failure to
rotate the tires as provided herein voids the treadwear warranty.
Note that if you use different size tires on the front and rear axles, your tires
cannot be rotated as recommended by Michelin. As a result, the mileage
warranty on each rear tire will be half that specified.

but yes, the all season will wear longer than the summer performance.
the 4s has a 15K warranty based on not being able to rotate.

I have the 22" 758i M wheels with 275/40/22 and 315/35/22 setup. Am i understanding correctly that I could do 275/40/22 on both front and back without changing the stock rims in the back? Although I can find all seasons in 275/40/22, I cannot find them with RFTs. Do you have any suggestions on how/what I can do for a square setup keeping my stock rims using A/S RFT tires.

Thanks in advance.

yes, the front and rear rims are within spec for 275/40/22. you cannot mount the rear rims in the front, so you cant rotate front to back.

i dont believe there are any all season runflat tires in either 275/40/22 or 285/40/22. i checked the close fit sizes of 285/45 and 275/45. nothing.

So .. get a spare tire and just do non rft? 275/285 is a width/preference thing... but are there any pros or cons going with the different ratios 40/45?

if you really want to do all seasons on the stock rims, that would be the best option. be prepared for sticker shock, the spare tire and associated bits and bobs are close to 1K when you get them after the fact.

i would probably go with 285, it seems to fit the rears better.
40 vs 45, 40 is stock, 45 should fit, taller sidewall, i was just looking at options to see if anything runflat was avail.

I was talking to my SA about going down this path and he said that he was a bad idea with the "wrong" tire size and a bad transfer case would be on me. Not sure I agree? Need some help to rebutt. Not too good in speaking tires. :-)
