New Tires and Rims ?????

If you are running a 205 70 now and you go to a 225 60 14 you will loose close to an inch in total height.
A nice compromise might be to put on a 235 60 14. I believe that tire is suppose to have a 6 inch min width, although I ran those tires on 5.5's ralley wheels with no problems.
I think most 4" BC ralley wheels 5.5 wide.
