Tire sizes / Handling, Need a pros thoughts Options

[ruby914]

I got a 911 front end and a set of 7 & 8 x 16'' 5 lug fuchs for my WRX914, not from the same car.
The Fuchs had a set of used tires that I have not yet replaced.
The front tires 205/55 had heavy wear on the inside tread when I got them.
The rears are 225/50
After doing an alignment I found the steering heavy and didn't center out from a turn.
If do a tight U-turn, best I can explain it, it feels like the tires are buckling over them selves or washing out?
I added a little more toe-in to help the centering but no change.
My first question: Would that wear on the inside tread make the steering heavy and not straiten out?

So, I need new tires.
Here is my delima...
On my other stock 914, I have 195/50 x 15 and really like the feel, very light, low and quick response with the smaller diameter tires.

The WRX914 will be a daily driver.
1st, I wonder if new tires will correct all the current problem?
2nd question, I think of going a step lower profile to 225/45 and 205/45. Does this choice sound reasonable?
But there is something else I feel I must consider.
When the turbo kicks in, in 2nd gear ( 914 transaxle ) if I am pushing it on a curved freeway on-ramp or if the street is a little damp it breaks loose easy.
So, I think of 245/45's in the rear and 205/50 up front.
But that is not doing much in keeping the diameters lower.
This is the tire size calculater I have used http://www.1010tires.com/TireSizeCalculato...p?action=submit
Is there any option that I have missed?

BTW
I now have GT flares sheet metal screwed to my car marked for trim and welding.
I have one uninstalled set of 21mm wheel spacers and I think I will need one more set, maybe the same offset.
I think, I should get my new tires worked out before I look at the spacers again.
