I had 195 and 185's on my Beta Coupe 2000 without power steering - frankly it made the car a pig to drive.
The purist coming out in me now and its just an opinion!
The Beta wasn't really designed for big ol' wheels and tyres like more modern cars, the handling was based on narrower tyres being used. Now later on in life when we decide that we want to be a little bit different and personalise our cars a bit, which I have no issue with if thats what you want to do, we throw bigger rims and tyres on and then wonder why A) its hard to move the steering wheel at low speeds and B) the car does not handle like it used to.
When I first bought my car it had 205's on it, they came off immediately because of the poor handling, I have thrown good money away going down to 195, then 185 and now I'm back to standard 175's.
I'm not saying don't do it - I'm just saying that you should prepare yourself for other things to change than "just the aesthetics" if you put on different sized wheels or tyres
