- The 195,205 number_ is the tire width in millimeters. The 50,55 number
- is the aspect ratio which is (side wall height/tire width)_in percent.
- EX if_the tire is 205mm_wide and the_side wall is 102.5mm high the aspect
- ratio is 102.5/205=.50_or 50(%).
-
- Going from 205/50_ to 195/50 to keep the aspect ratio the_same the
- tire wall height_ must decrease.__I'm not positive but I believe the
- decrease will have to be 5mm. This means the overall height of your
- tire will be 1cm shorter. This may or may not be noticable.
- Some rough calculations show the diameter of your 205/50 to be 23.07inches
- and the 195/50 to be 22.68 inches a diff of .39 inches. The 195/55
- has a diameter of 23.44inches.

- Hope this helps (and is correct_:-))
