For OEM-like fitment w/the ZTK package you will need 21mm spacers in the front and 24mm spacers in the rear. So I'd look for 20/25mm.

It's strange they would set you up with four wheels the same size, yet stagger your tire sizes. It's even more strange they would put 255's on 8" wheels, as that's outside TireRack's recommended range, and the 245 is at the minimum recommended range for an 8" wheel.

There's absolutely nothing wrong with quality hub-centric spacers, and anyone that tells you otherwise ask them to prove it. Having said that, you're going to need some pretty big (heavy) spacers.

Looking to get these wheels for winter on an incoming 240 with the ZTK package.
The offsets are slightly different.
Front is 30 vs the stock 25 and rear is 42 vs the stock 35.
Would these be OK?
For ther front wheel the comparison tool says:
"Tire is 5 mm closer to suspension components. Rim is 5 mm closer to suspension components. Acceptable for most cars"
and
"Rim offset is more than OE, so brake support will be closer to the rim. Make sure they are not touching."
For the rear it says "7mm closer to suspension"

https://www.wheel-size.com/calc/?whe...cl=30mm&sr=0mm

What do you guys think?

Just to confirm - these wheels above fit a car with ZTK package.

Got my car yesterday, so I went to 1010tires in Mississsauga to get the winter wheels test fit and installed (with Continental snow tires).

I put 5mm spacers at front and 10 at the back to get as close to OEM as possible, but more would be required to make them look "not as bad".
Don't know what the impact on handling would be, so will stay for these for this winter.

What was your reasoning for not going with a 9.5" square setup?

This is winter wheels and snow tires. I live North of Toronto and we do get a lot of snow. Wider not better for snow.
There is so much guessing out there and so little real info for winter wheels for this car with ZTK - I just got tired of searching.
This was closest to OEM that I could find, at the time, and also available in Canada. Not going for looks, or anything like that. Just something that takes me through the winter.

Wheel/tire setup looks great!
I was looking at the exact same wheels but in 18 for winter setup.
Too bad you couldn't make the car meet, I would have liked to see the setup.

But ended up with these:
https://rtxwheels.com/products/rtx-r-spec-ff10-gunmetal
18x8 42 offset.
Crap.. I may have to put spacers too for my setup on m240i which I didn't when it was on m235i GC.

[Saturns]

Can someone confirm if this is stock offet for Track or Sport Package?

The stock/OEM 893 Performance Rim & Tyre package is:
Front: 8.5 J × 19, 245/35 ZR19 Offset 27
Rear: 9.5 J × 19, 255/35 ZR19 Offset 40

What is the offset for stock RFT?
19x8.0, 225/40 R19 RFT

And if I go with 18 x 8 square setup for winter setup what offset range should I stay within?

Thanks for any help. I did look through a few threads and most postings are on 19's

those braelin wheels look great, the rears with +42 offset seems nicely concaved.

Yeah. Saturday turned-out to be super-busy. I wish I had time for the meet. Aside from getting wheels, I put the Boxster in winter storage, so that took a lot of time.

As for 18 in wheels on ZTK - I know somebody on this forum has done it - but it really depends on the shape of the wheel too.
Lead-times on most wheels are fairly long now - I did not want to risk getting 18s and having to return them in case they did not fit. So went 19. Also - a couple of places where I asked - all charged serious “restocking fees” for wheels. Up to 50%.

Talked to my wheel/tire shop and yes chances are I will need this for my setup as my wheels are 18x8 42 offset.
And you mentioned above my guy also said it is ok/good to use 'hub-centric' spacers that are 15mm-20mm+ with some meat (with longer bolts) vs. the thin 5mm-10mm that are not hub centric which can sometimes cause vibration because its not sitting flush...something about sitting on the bore..or something.....

[Beware-of-the-Phoggy]

Installed some new wheels & all-season tires for the mild North Carolina winter onto my M240i without ZTK.

Moda MD27 Machined w/ Black Accent, 19" x 8", ET35 (from Tire Rack)
BMS spacers (13mm front, 10mm rear). I put the wider spacers up front to make up for the extra offset compared to stock ET27.
BMW center caps are 68mm cheapies from Amazon. They fit a little loose, but I think they'll stay on. If not, no big loss.

Tires are DWS06+, 245/35 R19 square.

Once I go back to the stock wheels & summer tires, I plan to swap the spacers to 10mm front, 13mm rear.

Tire Rack shipped the wheels with 66.5mm plastic centering rings installed. I had a hell of a time getting the wheels seated on the spacers (or directly on the hub when I tried), even using a hanger pin for alignment. Was very challenging to get the extended lugs to catch, and had to go around in the star pattern just a liiiiittle bit at a time to use the lugs to pull the wheel onto the hub evenly.

This was my first time doing any of this - wondering if I should have removed the rings instead of forcing the wheels on with them.

Trying to source for summer wheels...
Based on some of the info in this thread and some other info in PM's will this work without poking over from fenders.

working towards these numbers....
245/40/19 19x8.5 ET12
275/35/19 19x9.5 ET22

Thank you XC3LLR8 for helping initially with some numbers.

I was able to get sizing on some wheels with this...

Front may need 10-13mm hub centric spacer
19x8.5
+25
5x112
66.6

Rear looks good for numbers
19x9.5
+25
5x112
66.6

Hopefully Im not far left field with this. Any input is greatly appreciated.

cheers,
Saturn

What are people recommending for track day wheels, I’ll be looking for something lightweight but not too expensive. What’s the go to option

Not sure if this will help but this is our VS-5RS fitment in 19x9 ET25 front and 19x10 ET38 rear. Tires are 255/35-19 front and 275/35-19 rear (rwd drive only). An xDrive recommended fitment would be: 245/40-19 F and 275/35-19 R

Our front wheel pictured would stick out 6.4mm more than your 8.5" proposed fitment.

The rear is the opposite and your proposed rear wheel would stick out 6.6mm more than the 19x10 ET38 in our photos on the outer edge. In your case I think the rear you proposed is quite aggressive and might need some additional negative camber or stretched tires to prevent rubbing. The front wheels you have in mind would be an easy direct fit.

Hope that helps.

I'd throw our name in the hat. We've got weights listed on our site at the moment for various fitments depending on what you're after. I'm currently working on an 18" G42 and G20 3 series fitment if you're after really light stuff but I need a final brake scan before we bring those to market.

19s we have covered with a few fitments. I don't think I can direct link here but my signature will take you to our site if needed. Even if you go with wheels from another brand, this guide might help you source tires and figure out offsets pre-purchase: https://support.apexraceparts.com/hc...-Fitment-Guide

You sure that's a safe recommendation for xDrive? That's a 2.3% variance.

Winter wheels
RTX FF10
18x8 (all four)
5x112
66.6
offset 42
- with 4x20mm spacers

Michelin X-ice 245/40/18

Unfortunately had to use wheels I recently bought for another car and couldn't exchange or return...hence the 20mm Spacers.
Tires close to flush if not 1-1.5mm poke. I believe it would be flush if I used 235 wide tires as 245 is max on 8 inch wide wheels.
So with 18x8 wheels search for wheels that have offset between 23-26 offset to get that flush look.

Thanks Tom.
After todays fitting of winter setup I may rethink the offsets and mine may not be as be aggressive. Some really like totally flush to top. Some flush midway through the wheel well. I'm not a fan of flush on top with the lower wheel well too much tire showing and shooting out gravel and dirt across the the painted quarter panel. Plus I do not have those flairs like some of the other car pics I noticed....I do like the clean look.
So ill have to figure out what offsets I need for my car..which does not have those flairs.

Looks like a pretty good fitment from the pics. Living where you live you may want to add mud flaps if the roads are constantly a mess. Can you swap out the 20mm spacers for 18mm or 17mm, maybe even 15mm if you're concerned about excessive road debris?

[Saturns]

I just drop off the car at PPF shop. The sides will have double layer PPF done around the area.

I think I've mentioned this to you multiple times, it's not what we recommend for xDrive. In the post above I was using the wheel offsets to compare to his proposed wheel fitments, but I know people will ask about the tire sizes so I posted those as well. We recommend 245/40-19 F and 275/35-19 R for xDrive in most cases or other sizes listed on our fitment guide.

It's not me that you need to mention this to. What happens 6 months from now when someone new is looking for wheels and scans this thread and sees your post saying "this is our...fitment" while showing 255/35 & 275/35 tires on a car with "xDrive" on the trunk? You not recommending that fitment on an xDrive in a post where you recommend that fitment with an xDrive pictured is about as clear as mud.

Maybe a simple disclaimer could help someone avoid a troubled transmission? I mean seriously, there's people on this forum that don't know when or how to replace their headlight fluid.
