Tire problems

["Bowen, Patrick A RP2" <PABowen@sar.med.navy.mil>]

On my spitfire I have a problem with the rear wheels scraping the fenders.
I have 7 inch rims on the back running 205/60/R13's.  The problem is when
backing the car squats down several inches!.  First is that normal?  second
is there a way to counteract it?  I have the air shock conversion on the car
and it helps but is not a cure.  It only happens on the drivers side (for
obvious reasons).    While backing the very edge of the tires are catching
the fender and digging in slicing them up.  Just trashed one.  

I know that 7 inch rims are too big, however they are very nice rare
Appliance Industries wheels and I would like to keep them, (unless someone
can tell me where to get a smaller pair).  

My solution at this point is to keep the air shocks very well inflated.  I
am preparing to order new tires and am looking at 195/60/13's  which are
1/2" shorter and 1/2" narrower.  something else I am contemplating is have
the machine shop shave the mounting face of the wheel down to bring the
offset more into the wheel well.  There is about an inch of aluminum at that
point.  Is there someone that knows how much I could get away with taking
off?  (Barry you out there?) .

What other solutions are there?
