Well just changed out the rear tire after about 8k miles but still had another 1k or 2k miles left before really had to change it but did not want to wait any longer. The new tire feels really good and it does get harder with age but not that much.
Pissed me off though because I didn't have the bike high enough and was trying to remove the tire and tilted it a bit to much and hit the studs that the wheel attaches to on the rim and put a small scratch in it.

Not to bad and touch up paint worked well but still did not make me happy. But I can tell you its soooo much easier to change a tire out on this than the 1500. It takes longer to set it up to lift than to pull the wheel and change the tire.
Already ordered another tire to have ready just encase and it was under 200.00. Wanted to do a small trip and didn't want to travel on a almost worn tire.
