[Tigers] Thoughts on 7" front wheels

[MWood24020 at aol.com]

I'm about to buy some new wheels for my Tiger. Because of the lack of  
quality off the shelf wheels for our cars, I'm leaning towards 15"  diameter 
Panasports. While kind of "belly button" wheels, they are very  well made and 
reasonable cost.
 
The usual 6" front/7" rear fitment has limited appeal, primarily  because 
of the handling compromises that result. I'd like to run 7' all around  with 
equal size tires. 
 
Anyone have direct experience with the 7's and clearances? My valence is  
near stock, we did do some basic smoothing, prior to the car going to paint. 
How  large a tire might fit? (I could see running as small as 195/50-15 at 
all four  corners).
 
Thanks for any thoughts!
