I'm a bit confused here. It seems to me that those of you who are using a 130/70-18, are putting a smaller diameter tire on your bike. No? As far as I know, the stock size is 110/90-18 on pre-2011 Americans. So the diameters are as follows:
110/90-18 is 65.5cm
130/70-18 is 63.9cm
Am I missing something here? Some of you have mentioned that the stock front tire size is 100/90-18, but I have not seen this in anything that I've read, nor is it the case on my bike.
I'm thinking 130/80-18 (66.5) will give a bit fatter look without too much profile height as does 120/90-18 with the rubbing issues.
