I've had them for a few months now and I'm pleased so far. They are definitely a softer tread than most but after talking with others that have the general at2 with a very similar feel to the tread, I'm hoping for at least 50k. As for the life of the lettering, I had mine mounted black letters out. That way if the letters start peeling I don't have to worry about paying to have them flipped. The noise level is a typical M/T hum. They have a very smooth ride and will hook-up really well. Hope this helps with your decision.
