Should I get a new rear tire?
Since I'm getting ready for a ~2200 mile trip in August, I was inspecting my tires. I have about 4200 miles on the stock rear ('06 919), and I'm thinking I probably need to get a new tire before I go. So first question, what is safe tread depth for motorcycle tires? I do have a little tread depth left, but I also have a flat spot in the center of the tire (darn you, straight MO roads!!), so there's not much left in the center. The front tire looks fine to me, which is consistent with reading other 9er tire threads here.
Assuming I need a new rear tire, that raises some more questions, namely, since the average (it seems) tire changing ratio is 2 rear : 1 front, should I stick with the same OEM tire now, or is it OK to switch to a better tire on the rear?
Don't need to know what kind of tires to put on, I can read that on other threads, just don't know if its a good thing to put different tire types on front and rear. Thanks in advance.
My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.
