Yeah so I'm looking to go pretty low on AP coilovers and I'm choosing a wheel and tyre package to go with it. My options are 195/45, 205/55 or 215/55. This is on 16x8 wheels btw.
Now I'm a fan of a lower profile so my instinct is the 195/45s.... but is there any advantage of going bigger? Would love to see comparison pictures if anyone has any

Ride will be better on the taller ones.
What's the standard wheel width? Might be worth ensuring that you can lower the spring seat past the top of the tyre at the width you want to go. Standard wheel will have the spring seat above it and the damper shaft only to the side.

I'm afraid I don't really understand half of what you're saying 
I'm getting adjustable top mounts and rear control arms if that helps...

basically if too big the inner tyre/wheel could rub on the coilover, I had this problem back in the day on my corsa B on spax coilovers.
If the wheels are 8 wide I would have thought you would want 215 for it to be a square fit. Or are you going for the "stretched" tyre look?

Those tyres will look completely different, and will be completely different sizes, massively affecting the speedo. What size tyres are fitted at present?
The 195/45/16 are almost 10% smaller than 215/55 across the whole diameter - they'll look completely different in the arch, and there'll be a 10% change in speedo between them too.

Need to know what sort of car it is, what size of tyres is fitted to it as standard to work anything out

These guys are both running 205/45 which look okay...
Hadn't considering stretch... so wider means less of that I guess. Not a massive fan of stretch but I think the above aren't too extreme.

I don't know okay
But basically decided I'll be running the same wheels, same tyres, and same suspension setup as the above car on the same model of car... who had the same standard wheels that I have lol. So, I guess if I'm happy with the above it doesn't matter too much does it 
Regarding the speedo, thing, I honestly don't really care. Will it be an MOT fail though? If so I'll the owner of the car above what he did about it.

Speedo you can verify with a sat nav, probably will just get it more accurate if the radius is larger. They under-read as standard.
And re my first reply - regular strut -
See how the spring seat is on top of the tyre, tyre size and wheel width can go up as far as you have room there, note also that offset will move the wheel in and out, left to right in that pic.
If you exploit all that space when you fit the coilover you then can't wind it down. It will typically have a smaller spring radius but it still needs accommodating along side the back of the tyre if you want it low.

I'm getting it professionally set up for me but thanks for the information! It's good to know what's actually going on  I know the guy above had to hack his arches about a bit... fine with me to be honest.

Yeah you always have the option to move the wheel outwards with either a lower offset rim or spacers - hence affecting the arch more.

Mini on 16's will be 195/55x16
you will be fine with 205's if you want to fit them, 205/55 is overkill, they wont fit.

Watch out changing the offset it can alter massively how the car feels to drive, get it wrong and your return to centre on the steering will disappear, and scrub radius will be to cock, makes it feel like its not connected to the road

I wasn't even given 195/55 as an option from the installer (sent me a load of wheel/tyre packages to look over) so yeah... I think I'll go for 205/45 as I know they will fit
