I've got some tires I am going to be replacing and I was thinking about up sizing from a 195/55/15 to 205/50/15 I believe the rim is a 6.5 inches wide am I wrong for thinking the 205 width will fit any input appreciated.

 

If your car is one which uses 195/55-15 tires stock - such as many Integras and '97-00 Civics - then yes, you can use 205/50-15 tires on a 15x6 rim, no problem.
