I just noticed last night that the GSXR has a 190/50 on the back instead of a 180/55 (previous owner put them on). I thought this would be a good excuse to show why it's a dumb idea to put the wrong size tire on the rear.
The front tire: 120/70-17 (stock size), about 1/4" chicken strip
The rear tire: 190/55-17 (too big, on a 5.5" wheel), a SOLID 3/4" chicken strip
So what does that mean to you (or really, to me)? Assuming that the tires would wear evenly with the correct size on there, that means that I've got 1/2" of tire on each side that is unused.... so my "190" is effectively more like a ~165 or so. By running a larger tire, I actually have LESS rubber on the road than I would with the proper size. Pretty sweet, huh?
