Looks great and you're welcome! Have you noticed any rubbing on the front wheel wells? If not, this may be the limit before rubbing occurs. I rub just barely but your hypotenuse is 3mm less than mine, which equals 1.5 less in the front of the front tire and 1.5mm less in the back of the front tire. A good test is a quiet, empty parking lot, windows down, steering at full lock and listen for any rubbing as you go from full lock to a few degrees away from full lock with the steering wheel. If you don't hear any rubbing and you check the wheel wells and see no lines on the plastic, then you're likely at the limit, which is awesome. 5-7 additional pounds at each corner isn't too bad. Have you noticed any mpg changes?
1) Yes, the hub centric ring simply helps line up the wheel when mounting.
2) You will want to use the appropriate lug nut seat type for the aftermarket wheel you are using. Check with the wheel manufacturer for the appropriate seat type.
The spreadsheet is updated to include @cocoloco with a possible front wheel well clear at 28.8" diameter and @Copland Navi with a new set of all terrain trails from Nitto, the Nomad Grapplers.

Yes, I finally installed them: Falcon V2 17x8 wheels, ET +30 offset, (V2 - Matte Black 17x8) wrapped in Nitto Nomad Grapplers, 225/65R17 (Nomad Grappler | Nitto Tire)
Immediate observations: more road noise with these tires. I'm hoping the noise dissipates a little after they're worn a bit, but I imagine final verdict is "plus" road noise rather than "minus" like you might get going with a higher quality set of all-seasons from stock. I'm also getting a lot of vibration at 60+ mph. I suspect something's up with the hub centric rings (STANCEMAGIC Hubcentric Rings - 67.1mm ID to 73.1mm OD - Aluminum). Amazon flags them as parts that don't fit the CX-30, despite me triple checking the inner diameter and outer diameter specs. I'm going to have Discount Tire check the balance again when they install OEM TPMS sensors (I wanted to keep them on the stock wheels) and make sure the hub centric rings are snug and installed correctly. If vibration persists, I'll get a set of plastic ones and see if there's any difference.
Thanks @KuroCX30 for updating the chart with my wheels/tires.

So since finding tires can be a chore sometimes in Canada, I am starting early for summer/all season replacements for the Turanzas.
Looking to fill the wheel opening as much as possible with taller wider ones.
From what I am seeing on the chart, for my stock 18’s on the turbo it looks like 235/50 18’s?
Already have aftermarket rims for my winter setup, so I will keep the stock rims for now for the summers.
Just looking for some confirmation on size(s) and any decent quiet noise recommendations.

A lot of people seem really happy with the Conti DWS06+ in 235/50R18 on the stock rims. Also seen good marks about the Michelin Pilot 4 AS too. I used to have Conti DWS06 on my MZ3 hatch and was always happy with the performance/noise/etc.
235/50 is OEM diameter at 27.3". Filling the wheel gap is going to require a plus size diameter. These would be my recommendation:
28.6" ‐ EXTREMECONTACT DWS 06 PLUS
SIZE: 245/55ZR18
I was hoping you would chime in, thanks.
Your setup has been added to the OP #1.

Discount Tire rebalanced them when they installed TPMS sensors, and the ride is improved, but a bit of high-speed vibration is there, and I can hear an intermittent rattling noise. I suspect the aluminum hub centric rings are not the right fit for these wheels, so I've ordered some nylon rings. Also, the road noise with the Nitto Nomad Grapplers is deafening, almost literally... my ears ring after every ride, even if it's just a couple of miles. I have tinnitus that road noise at the right frequency exacerbates, and I had none of that in the CX-30 till now. I'm sure Discount Tire can accommodate me to switch them out for something else, but now I'm worried any of these hybrid AT tires will generate the same amount of extra road noise. Should I try out the BF Goodrich Trail-terrain or the Wildpeak A/T Trail?
If that's the case I would swap out for the Wildpeak Trail immediately, although, like you mentioned you may be extra sensitive to road noise frequencies. 🤔 The WPATT is one of the best rated when it comes to noise, so if it doesn't work, i'm not sure what's left. I had high hopes from other reviewers that the Grapplers would be comparable to the WPATT both in performance and noise. Bummer. Discount Tire will for sure swap out for you, they are great when it comes to not being satisfied.

Ok, here's an update: Discount Tire replaced my Nitto Nomad Grapplers at 225/65R17 with the Falken Wildpeak A/T Trails at 215/65R17.
I feel the noise they make is actually worse.
I chose this size because it's at the upper limit of what "fits" on the CX-30 according to Discount Tire (although we all know we can go bigger still with no rubbing). I thought bringing down the tire size to more closely match stock would help with noise. But that's my first mistake: I think these calculators are considering stock/standard wheel dimension, with a width of 7", so using the calculators for percentage of changes between 215 and 225 were all off because I wasn't considering my aftermarket wheel specs at 8" wide. I suspect a lot of these measurements (and positive reviews) are based on stock wheels, right?
I can see how the tire tread edge is "digging" into the pavement; just a handful of miles, I pulled over, and I can see marks right along the edge. It's probably why I hear so much more road noise.
TireRack shows Rim Width Range for this size Falkens at 6-7.5" (although Discount Tire says limit is up to 8"). At 225/65R17, range is 6-8". Now, I noticed there's a stat for Tread Width that I never paid attention to, and I wonder if that's a factor with the noise to consider compared to wheel width? For 215/65R17, it's at 6.3". For 225/65R17, it's at 6.9", for 225/60R17 at 7.1". For BF Goodrich Trail Terrains at 215/65R17, Rim Width range is 6-7.5". At 225/65R17, limit goes up to 8" and tread width is 7.4", even wider. Nitto Nomad Grappler at 225/65R17, tread width is 7.1" (215/65R17, rim width is 6-7", so glad I didn't make THAT mistake with that tire). I notice the BFGs don't have that aggressive edge design the other tires do, so the overall look of the car won't be as aggressive as with the other two. Another incidental thing I learned is that the Nitto's are rated XL and the Falkens and BFG's are rated SL.
I immediately went back and asked if they can slip the Nitto's back on, but they said they're required to send them back to the manufacturer once they're off the customer's wheels.
Ultimately I may just have to accept that, if I insist on riding on these hybrid AT tires on the Falcon V2s, I'll have to deal with the added noise. I might try the BFGs at 225/65R17 anyway (I have 30 days to decide, just have to pay for mounting again). It could be that I go back to stock wheels (or wheels with stock width) with these new tires and sell the Falcons, too. It could be that my comfort supersedes tire durability and will just have to stick with stock tires and wheels. We'll see.

Replaced my stock rims and kept the same Pirelli Pzero Nero 235/50/18 tires I originally had on OEM rims. Rims are Anovia Night in Raven black. Size is 18 x 8.5 with +35mm offset. They weight 19lbs each. 8 lbs per wheel reduction makes the handling and acceleration noticeably better.

Congrats, looking good. Unfortunately, you made up the lost weight from the lighter wheel by adding a considerable amount of weight with the tires, putting you at about -1 lb per corner. Since the majority of that added weight is tire weight, located further away from the center of the wheel, it's likely a wash with regards to overall weight. No offense but any acceleration performance difference is likely either placebo effect from thinking the setup is lighter or gaining a negligible amount of grip from a wider tread width. The wider tread width should be noticeably better for handling though.
Updated spreadsheet includes:

Thanks for info. Did a lot of research but never thought to look at OEM tire weight since the Pirelli's had been on awhile now. The tires were added awhile back so the extra tire weight was already on the vehicle. That's what I was referencing for comparison point. As bad as OEMs are they are a remarkably light tire.
Budget was a little tight so I have to wait on getting lighter tires. Decided to eventually go with Continental Extreme Contact DWS06 all season since they are only 25lbs a piece and have a nice looking tread pattern and great reviews. Are also the 2nd lightest performance all-season besides the General G-Max at 24lbs. These numbers are only for 235/50/18 sizes.
That makes sense now. Dropping an extra 5 lb at each corner in the future should also be noticeable. Nice start!

First image is with Nitto Nomad Grapplers in 225/65R17.
The second image is Falken Wildpeak T/A Trails in 215/65R17.
I think I'm going to eat my hat (because there will be nothing in my wallet to eat after I'm done) and switch them back to the Nittos in the 225/65 size. Discount tire has a 30-day satisfaction guarantee, but I do have to pay for mounting and certificates... on five tires... again... ugh. Noise difference is the same (maybe even worse on the smaller tire?) and the 215 just doesn't look quite right on the car. Among the many things I've learned with all of this: Nitto Nomad Grapplers are XL rated, whereas The Falken and BG Goodrich equivalents are SL rated.
