Checked the stamp on the side wall.. last 2 digits are 06, so they are definitely the original ones.
Since the tires have over 9K miles, I think it's time to shop for new ones.
I was going to get the Pirelli Sport Demons since a lot of people are saying they are good, but they also say that one of the downsides is they have a "negative effect on turn-in". Ehm... say what? Anyone care to explain what this may translate into? Anything a non-expert rider like me should worry about?
I just want sticky tires that will not let me down!
