I had to put bigger tires on the rear due to a flat and the tire shop I limped to did not have the 205's.  So I ended up putting some cheaper toyo's on that were 215 40's.  The rear is now is slightly larger in width and height and actually I like the way it works with the short first/second gearing.  Lets me stay a hair longer in those first two gears.  I think I may stay with this combo when I match up the set with new toyo TS-1s or RA's later.
