2018 OEM 17" wheels

I just purchased a 2018 premier and have been looking for wheels for Winter tires. I guess it's a little early for take-offs since the 2018 models now have a 5 x 115 bolt pattern. I plan on buying a set of 17 x 7" OEM take-offs if I can find them. I plan on using 225/65R17 snow tires. (Same diameter as stock 225/60R18's used on premier).
I've noticed the 2005-2009 Equinox used the 5 x 115 bolt pattern, (2010-2017 wheels are 5 x 120), but I can't find center hole specs. and the lug studs are 12mm instead of the 14mm used on the 2018 models. I might consider some of the wheels offered by Tire Rack but don't know center hole size of new wheels.
1. Has anyone found a source for 2018 OEM wheels?
2. I suspect the Malibu uses the same wheel specs. but can't find anything on them either.
3. Has anyone used 17 x 7 after-market wheels on their 2018?
HELP!
Thanks,
Howard

Can't understand why GM insists in changing bolt patterns on model re-designs. Seems like all MFGs should be required to standardize.

Update: I put my 2018 Premier up on the lift this morning to take some wheel dimensions so I could shop intelligently for some wheels for winter tires.
These are 18" wheels but offset, bolt pattern, center hole size, bolt hole size and lug stud size should be the same as the LT 17" wheels. I believe the 17" wheels are also 7" wide. Here's the info.
Size: 18x7J IS43 (I assume IS is Chinese for offset based on my findings below)
Bolt Pattern: 5 x 115
Lug Size: 12 x 1.5mm
Center Hole: 70.358mm (approx., converted from SAE measurement)
Hub size: 70.231 " "
Width: 7"
PN (18"): 23201279
I don't know if this will help anyone but I'm going to use this information to check for a proper fit using the following web site:
https://www.wheel-size.com
Your input is as good as mine, so add to this as you learn more about the 2018 wheels. I would like to get PN for the 2018 17" wheel if anyone has one off. (It's on the back of one of the spokes).
Lets get this done!!

I don't think all the GM vehicles uses different bolt patterns (I can be wrong though) because I know many people uses the new truck's wheels and fit it in their old trucks

Vic1212, Don't count on it! Just to give you an idea of the diiferent bolt circles, my Chevy Trax is 5x105, the 2005-2009 equinoxs are 5x115, the 2010-2017 equinoxs are 5x120 and the 2018 equinox is back to 5x115. That's not all; GM, in their infinate wisdom used wheels 16"-19" (stock and optional), years 2005-2018. There were also at least two different size lugs used, (12 and 14mm).
I've corrected two wheel suppliers who ass..umed that the bolt pattern for 2018 was 5x120 as it was in 2017.
I dug into the link I posted above that I have counted on for other wheel searches and found errors there too. They show a 5x115 wheel with all specs. matching our equinoxs, turns out those wheels were only used on Buicks sold in Asia. (I didn't want to go that far for wheels).
I plan on arranging to try one of the 17" 2005-6 at a local salvage yard to see how they fit, (all specs. look right), we'll see.

A lot of GM FWD cars from the 90's-00's used 5x115mm Bolt pattern. Bonneville, Grand prix, Lumina, Regal, Intrigue, LeSabre, Park Ave, Seville, Deville are the ones that come to mind initially. They also appear to use the 70.3mm center bore. The offset is ET51ish though, so not sure if that will affect it.

Hey jimmyfloyd, good to here from someone who does the research. I thought I had entered a dead zone. I researched wheels using the same source. I took all the measurements from one of my stock wheels and entered them into the program. I then increased +/- offset leaving all other data exactly the same as my wheel, ie. dia.,width,bolt pattern and center hole. I only had to +/- 2-3mm to get closest. If you do this you will come up with a bunch of Buick FWD cars. I found that the Buick Verano came closest, (within 2-3 mm, less than 1/8"). I just got back from pickng up a set today. I plan to confirm there fit tomorrow and will post results. By the way, I used Hollanderparts.com to locate the Verano wheels. The site allows you to put in your zip code to sort sources closest to you. In most cases there is also an assessment of the wheel's condition and price.

This will be my final post on this subject unless I can answer a question that may come up.
As I said above I tried the "new" Buick Verano wheels on my 2018 Equinox today, and everything worked perfectly. Even the bowtie center cap fit the Verano wheel. My Equinox wheel happens to be 18", that uses a 225/60-18 tire. The LS and LT use a 17" wheel with 225/65-17 tires. Offset, Center hole, width and bolt pattern are the same for both sizes. Diameter of tire and wheel are equal because of the profile difference (60 vs 65). I am going with a 17" wheel because 17" tires are cheaper. Here is the comparative specs. for the Equinox vs Verano wheel:
Width: Verano= 7" Equinox= 7"
Center Hole: Verano= 70.3mm Equinox= 70.3mm
Bolt Pattern: Verano= 5 x 115mm Equinox= 5 x 115mm
Offset: Verano= 44mm Equinox= 43mm ( Less than .040 difference)
Part Number Verano= 22758350 Equinox= 23201239 (18")
Based on my research, the correct TPMS sensor is PN 13598772. They are available on EBAY for less than $12 ea. in "4-packs".
Hope this helps,
Howard

I was wanting to say it might work just as one is a Delta platform and the other is a D2xx even though it's still part of the delta platform
