12K mi, that's 19K km. I've never gotten that kind of mileage from a front tire so I would consider this excellent.Road 5 front with only 12k miles. Not the long mileage I was hoping for.
that is exactly why i stopped using the angel gt gen 1. it was like paper at the end of life.Its almost hitting the TDM and if you want to know how much rubber is left in the center, just release all air and press the center with your finger, you will get a good feel of the tire. If it goes in or bends in without much pressure from your finger, then high time to change.:goodluck:
