this is a very daring comment to make which can lead one to buy wrong tires 
the offset alone does not make a difference to how far out the wheel looks like - the real difference is a combination of offset and width of wheel. izzy34 was talking about a wheel with a width of 10,5", and cmansbimmer was talking about m5 wheels that have a width of 9,5". eventhough they roughly have the same offset (m5 have an offset of 28), the wheels that izzy34 are talking about will stick out by nearly a cm more than the m5 wheel at the back. Here is my calculation:
10,5 wheels: (10,5/2)*2,54-(30/10) = 10,335 cm
m5 wheels: (9,5/2)*2,54-(28/10) = 9,265 cm
i am first taking center point of the alloy (ie. width/2) -> converting it to cm (multiply by 2,54), then subtracting the offset (divide offset by 10 to convert from mm to cm) from that.
This number tells you that the furthest part of the wheel is 9,265 and 10,335 cm away from the mounting point.
To give you an example of my car - i have 9,5 in the rear with offset 17. on top of that i have 3mm spacers. This is how it looks like:
http://www.syed.at/e60/rear.jpg
from my above calculation, it is
(9,5/2)*2,54-((17-3)/10) = 10,665 cm
so from that point of view, your 10,5 wheel would be 3 mm further to the inside than my 9,5 wheel.
Now with that in mind, what could be a problem is the rubbing inside - your 10,5 wheels will need 2,8 cm more space inside than my wheels. i can not tell you now whether there is sufficient space.
I hope this was of help.

one other point i forgot to mention is - 275 in the rear on 10,5 could make the tires look a bit small, ie. the outer wall of the tires might not be aligned with the alloy. i think our friend Nick from Greece did quite a bit of homework on tire size vs. tire wall vs. looks. you would have to do a bit of search on this.

Thanks for the comments,
I have looked at the calculations even though i am not good at this type of calculations, but there is a point just makes my mind mixed up at those calculations and comments.
Here is what you have mentioned, please correct me if i understood wrong,
"so from that point of view, your 10,5 wheel would be 3 mm further to the inside than my 9,5 wheel.
Now with that in mind, what could be a problem is the rubbing inside - your 10,5 wheels will need 2,8 cm more space inside than my wheels."
On the upper sentence, you have mentioned that mine 10.5 are going to be 3mm further to the INSIDE than your 9.5 wheels and then on the lower sentence you have mentioned as "your (mine) 10.5 wheels will need 2.8 cm more INSIDE than my (your) wheels,
so, is it 3 mm or 2.8 cm needed in INSIDE, if 3 mm, just guessing it will be fine as i read people using 19X10 ET20 with no major issues, comparing 10s with ET 20 to mine 10.5 ET30, guess it will be fine, but as i said just guessing...
So what do you say?
Looking forward to hearing from you and any of forum members has knowledge on this issue.
Thanks

Thanks for the answers and sparing some time by reading and answering.....
But still i would kindly like to hear an answer like yes
these wheels
19X8.5 ET15 245 35 19
19X10.5 ET30 275 or 285 30 19 will fot or will NOT fit, cause i am getting a little bit confused......
So what do you say rysed?
Thakns again......

His current configuration is 2mm different than mine. Meaning it's pushed out 2mm more.
have you changed your configuration? as far as i remember, you had ET 28 with 10 mm spacers, or? if so, our delta is now 4 mm - have added 3 mm spacers on my et17
cheers

there are two walls on a tire - the outer wall, and the inner wall. My first comment was that the outer wall will be 3mm further inside than my m6 wheels. In other words, my wheels in my configuration stick out 3mm more than your 10,5" wheels with ET30. So from my rear picture, you can tell roughly how your wheels might look like.
On the other, because your wheels are extremely wide, ie. 10,5" your inner wall will need additional 2,8 cm inside than my wheel.
here is a quick pic that i have drawn. It is a picture from the top. my wheel is black, yours is red. sorry for the poor quality.
So now to your question, will they fit, or better, how can one predict whether the wheels will fit or not? Well best is to compare with other wheels that do fit. We know that the outer wall is no problem, because it sticks out less than mine, so there will be no rubbing on the outside. In fact, if someone took a picture of their 166 wheels with 10 mm spacers, that is exactly how far your tires will stick out. on the inside, we for sure know that a stock 172 fits - that is 9,5 et 32. So therefore:
(9,5/2)*2,54-(32/10) = 8,865 cm from mounting point, therefore inside it needs 15,265 (9,5*2,54 - 8,865) from mounting point
your 10,5 inch:
(10,5/2)*2,54-(30/10) = 10,335 cm from mounting point, therefore inside it needs 16,335 (10,5*2,54 - 10,335) from mounting point
this means that your wheels needs 1 cm more inside space than the stock 172.
I know i am not of any help, but i hope with this calculation, you will be able to do the same homework for configuration that do work. from there you will know whether the wheels fit or not.
sorry about this
cheers rumman
ps edit. i have attached a second picture that gives you a better picture. hope this is of some help. cheers

Case in point, my first tires were Toyo T1Rs, 275/30/19. The Toyo tires looked stretched on the 166 wheels and ZERO rim protection. My current tires, General Exclaim UHP, 275/30/19, fit the 166 wheels fine without any stretched look and offer some rim protection.

I edited my comment and deleted what I quoted. I was incorrect. Sorry izzy! Didn't mean to confuse you. rsyed definitely knows his stuff, so I would listen to him. Nice explanation by the way rysed. Where were you when I needed help with choosing wheels???
