to see the changes in different tire sizes try this:
enter your sizes in the appropriate boxes and it will show & tell you the differences.
It will also tell you how much your speedo will change and which way (faster or slower)...
my 95 Legacy came stock with 185/70R14s - after a forester strut lift I am running 205/65R15s with no rubbing or any other issues.
could have run the stock 98 Forester size - 205/70R15 - but it was mighty close to rubbing in front on turns, so I opted to drop the sidewall just a little.
on a side note, the tire size calculator said my speedo would be too slow by 5.4% (60 on speedo would actually be 63.2)- using a GPS speedometer app to check it, it is almost dead on...
