Width wise I run a 245mm wide tire. Stock is 225, at the biggest. My sidewall height is .3 inches shorter than stock putting it at 26.7" total height, stock is at 27" tall. Supposedly tires up to 27.5" can fit, I believe that was at a 225 width.
when switching wheels or wheels and tires size is rb scrub a big concern or not that big of a deal? after doing research it looks like 0 or a negative run scrub is better than a positive scrub

When you're referring to "rub scrub" do you mean the overall diameter of the wheel? I.e. a taller or shorter tire?
I'm my example above I went with a 0.3" shorter tire overall, putting it at 26.7" tall, compared to the stock tire height of 27" tall. But my tires are much wider than most others by about 20mm.
Some people go much taller like a 27.5" tall tire, but stay around 225mm wide, which is standard on the S models, while staying at stock ride height.
Tell me your goals and what you plan on doing with your wheel and tire setup (wheel size and tire size goals) and I can help direct you in a better direction as far as my knowledge goes. Do you plan on lowering, raising, etc.
I put some 225 50 17 Continental Extreme Contact DWS on our Countryman about 20K miles ago. The ride was drastically improved (comfort and performance). Gas mileage did not really suffer from the larger contact patch. The width is bigger, but there is no rubbing. You want to step down to a 50 from a 55 since the sidewall number is a ratio of the sidewall height/tire width. so a 50 in a 225 width will be roughly the same as a 55 on a 205.
keep a can of fix-a-flat in your boot and you're good to go. I've never looked back.
We do live in a new neighborhood, and with all the construction, we get a ton of nails and screws in our tires. Those usually stick in there and cause a slow leak (because they plug the leak for the most part). It's slow enough to fill the tire and drive to Discount Tire to get them to repair the tire.
I played around with the numbers a 215/55 would be and other that the 1/4 you gain in sidewall, the amount they stick out and the measurement between the tire and the suspension is less than the 225/50's are. not sure why they wouldn't also work. want to get just a tad more sidewall to help protect against potholes
I've never heard anyone mention scrub radius there is not enough room to change offset much anyway
anyway
I never hear about it either till I started doing the measuring of different tires on existing rims and different size rims with a different offset
the countryman has 50mm offset wheels, the closest I found were 47mm offset in a 17x7.5 after market wheel/ MSW TYPE 27
well, I should say that's what I found in my price range anyway
Im new to these Mini's I just took the stock run flats off and replaced them with 225/55/17 regular tires. It made a huge difference in ride quality I think. I just have to figure out how to get the tpms light off.

my goal was to add just a tad sidewall more sidewall but staying in the parameters...right now i'm looking at putting 215/55r17 on OE 17x7 wheel 50mm offset or optional after market wheel MSW type 27 , 17x7.5 wheel with 47mm offset
my goal is to run the 205/55r17 runflats for now because they are pretty new,came on the car..and have the ability to run 215/55's (more tire option) and 225/50's if I decide to go that route
run scrub = simply explained its the point at which the bottom of the tire has most of the pressure on it touching the road..the distance at the road surface bewtween the tire center line and SAI line extended downward thru the steering axis..basically where the center line and the angle of your strut/shock meet

so you went with 225/55's? were the originals the 205/55's? that's really close to the top of the fender?
doesn't look like much room if you go over a wavy part of the road( R.R. tracks or bumps)
theres a way to reset it in the book for the car, but I think I will try to get the garage to do it for me

I used tire-size.com and used the offset calculator
and wheel-size.com and used the rim & tire calculator
Although Tire Rack wouldn't guarantee a fit for the 215/55's.. everything I checked on seems like they would be ok ,on the original 17x7 50mm offset
and the 17x7.5 47mm offset

The site I provided does both in one, it's pretty handy. Even does an overlay of your current setup with the new setup.
Go for it! Seems like you're ready to upgrade to awesomeness

your clear when you turn the wheel? the inside front or back of the tire doesn't rub the inside of the fender?
I went from the 205/55 r17 Pirelli All Season RF to 225/55 r17 Indy Firehawks 500 Ultra Performance Summer tires. yes, these are 1cm taller than stock due to the size. The correct size should be 225/50 r17. The Difference is night and day.
Better ride comfort, less road noise/cabin drone, less expansion joint bumps (doesn’t feel like you are hitting speed bumps) less shock when hitting minor road imperfections.
I still use the Pirelli SottoZero Winter RunFlats just for peace of mind
When going to 225 width make sure you bend the pinch welds down in the rear tire wells. They tend to rub the tire if you don’t bend them out of the way.

Reason: Advice
From 205/55 to 215/55 the size is a direct swap. To go to 225 width and match the side wall you have now you need to go 225/50 this will give you the same sidewall height as the stock 205/55. If you want more height on the sidewall on the OEM 17” wheels then you can go 225/55. Anything taller and you risk rubbing.
As for aftermarket wheels. The OEM is a 50 offset. This is pretty deep in the well. You do not want to increase this number if you want to increase your width (do not go 55 offset). Instead you want to decrease this number slightly to make for a better fitment (between 40-47 works well, keeping the width close to OEM (7.0”/7.5”) works well.

yeah the 205' are 25.8in in diameter the 215's are 26.3in..circum 81.3 to 82.6 and 205's sidewall is 4.4in in height and 215's are 4.6in not a exact swap but increase do seam pretty minimal
tiresize.com has a wheel offset calculator is used also that's pretty good.pretty easy to read

so,,,what do you do about the bolt pattern?. stock is 5x120
The R60/61 and the current BMW’s share the same Bolt Pattern (5x120). You can change width, diameter and ET (offset), but the bolt pattern remains the same.

the problem is none of those 50mm wheels have the 5x120 bolt pattern
I was looking at a wheel that had an offset of 47mm, just 3mm off. But the guy at the shop said he would be concerned with that..set up would be off and could cause damage to wheel bearing,ball joints and other suspension related parts
might have to see if I can find someone that would swap the silver OE wheels for the blk OE wheels

That is not the case. If you were going for the extreme, maybe. But you would have to be driving like an absolute imbecile.
3mm is nothing in the grand scheme of things. I went from 50 offset to 42 and still do fast runs. Haven’t gone to the track with them yet but that opportunity will come soon enough
Look at the different offsets that are offered. They wouldn’t include it if they didn’t fit, but keep in mind that this is all for R60’s with stock ride height
