So if I had a set of winter tires 275 40R20 and 315 35R20 would they not work on a set of 20" rims with the new bolt pattern and offset?

It's a pretty big difference for circumference.

So we're talking about the speedo not being in sync.

Question: If i were to go a small size up on the the winter tires, would it be a problem? What I mean is: instead of 275/40/21, what if i went 275/45/21? I understand there is an inch difference in size, and I'm not worried about the speedometer,I just wonder if it will rub or cause any mechanical problems.

Thoughts?

They fit on the M brakes and with they are exact match to oem specs 740m tires us spec.

Enkei performance onx black
20 8.5 et 35
Blizzak dm v2 275/45/20 - close to oem diameter
Square setup got them via tirerack ask for gill

Front clears caliper with 1/2 inch to spare
Rear clears with 3 inches spare

X5 g05 Tightening torque is 101 lbs/140 Nm per manual

Btw- once you are done with the install, go to idrive and change the tire setup from summer to winter and reset tpms. For the square setup i have bmw recommends 33 f / 41 r in the idrive. As per TR, If you are on brand new winters over inflate them for the first 300/500 miles by 5psi to help the bead set especially if the ambient temp is above freezing.

Did those tires come from a staggered set up.
If so you might need staggered winter rims for those tires.

Awesome!!! Thanks for being the first to post about aftermarket wheels and fitment for winter set up. This will help tremendously for those who are looking for wheels, since they're not even available for the "new" bolt pattern.

Thank you for the pictures. Would you mind taking a full side picture with the car ? I want to see how they look on the car. Thank you.

Thx, still trying to find the right rims for my old winter tires. What if I can't find the rims with exactly the same offset info, should I go for higher or lower? (Many of the rim has a offset like 35mm, 40mm or 45 mm, but my previous wheel has a offset info like 40mm for the front, and 37mm for the rear)

Perfect. Now I am convinced.

Two questions.

1. Can you replace center cap with bmw one ?

2. Do you have email address for the sales guy who sold them to you ? I would like to deal with him directly if possible ?

Thank you.

Yes, you can pop the caps off and put bmw ones.

Only have his extension; Gill x4620 at tirerack. They are also running a rebate on the blizzaks if you order before the 3rd.

Btw- if you go online to tr.com and choose vehicle 2018 540 the set shows up with the correct wheels bolt patten and et and tpms.

Thanx. Found him. https://www.tirerack.com/content/tir...s_contact.html

Will try your suggestion right now.

If you have M calipers you should stick with 20" for winter rims.
I was told by my tire dealer 19" rims don't fit around the M calipers.

If you don't have M calipers you should go with 19".
Rims and tires are cheaper and better performance in snow.

But if you don't care about cost then 21" would look better.

I agree with this perspective.

There is limited choice of winters tires in 21, i believe pirelli scrotto zero is the one available easily in the us and you end up with 275/40/21 as tire size choice.

Going to 20" gives you access to michelin x ice, bridgestone blizzaks, and yoko iceguards. So way more choices in addition to raising the sidewall to 45 as added benefit. Try getting a square setup as you will be able to rotate tires, and it also helps the under steer feeling.

Thanks for your tips, After so much online research, I decided to get the following rims for my existing snow tires:

Niche Vosso Matte Black: 5x112mm 20x9in ET38 (For the Front 275/40R20)

Niche Vosso Matte Black: 5x112mm 20x10.5in ET40(For the rear 315/35R20)

The only problem is the center bore of the rim is 66.5mm, and the X5 G05 is 66.6mm (from one of links provided). I wonder if they would fit? Are those numbers suppose to be the same? maybe it was rounded it up, and hence the confusion?

Other than that, the wheel for this set up is a little bit smaller in total diameter than the original 22 inch wheel (about 0.9 inch), I think it should be fine.

It should be fine. But if you're picking up the rims from a shop you should ask them to try the rims on first before paying.
That's what I asked them to do for my M235i with sport calipers.
It's easy. They just Jack the car up and switch the wheels on the front and back, then spin them to make sure there's no contact.

Too bad it's online, and their shop is in Ontario (I'm in BC)..... they do have a return policy tho, but it would be so much nicer if I could just try them on first.

Are there no niche dealers in your area.

Type in your postal code
http://www.nicheroadwheels.com/dealers.cfm

There are many dealers in Richmond, Burnaby, Surrey etc.


Or contact the customer service they might have a way of confirming they will fit before paying.

I know I am bumping my own question here, but I am trying to NOT have to get winter wheels for the short time i have left here in Germany and I saw a set of winter tires that are:

275/45/21 Front
315/40/21 Rear

I can spend a lot less and have them for just the season before I return to the US.

Thoughts? Comments? Concerns?
