Hello,
yes I did fit new tyres, I think I wrote about it in another post about tyres so I forgot about this one, sorry
I went for the Dunlop SP Sport 02, 195/60/15 which proved to be breat tyres (at least compared to the OEM ones). They fitted just fine and they don't seem like they're too wide for this rim. They just look ok and in place. The tyres now look wider (there is noticeable difference), although I guess they would look even better on a wider rim.
As for the height, 195/60 is slightly higher but I guess that's ok, the car goes great. I did notice some difference while driving, compared to the old tyres but I think it's because of the new tyres being *new* and wider. For example, I noticed that the steering response got kind of quicker.
So, I can't tell about the dimension of 195/55 (as stated in the thread's title), but I can tell you that the width of the tyre is ok and that the 195/60 run fine!
