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.

How much (gulp) does a laser alignment rig like that cost?

How much (gulp) does a laser alignment rig like that cost?

The alignment stands/turntables were not included. I built them for my first alignment machine. (sourced from E-Bay). The problem with my first alignment machine was age. I could no longer get anyone to calibrate it. My second alignment setup (as seen here) was also purchased used. This one, however, was totally refurbished by an authorized service center and came complete with new wheel clamps and a reconditioned Dell PC.

It wasn't too bad considering that I do all my alignments (we have many vehicles) and I can get it set up exactly like I want it, and I don't have to go through the hassle of putting the race car on a trailer to take it someplace then have to go back later to pick it up. You won't find a whole lot of alignment shops that take the time to really get the settings just right. I probably should start doing alignments for others, but don't seem to have the time. (It was about half the cost of a decent 911 engine rebuild)
