Recently I turned over 20,000 miles on my new front end and thought I would share here where things are with the Hannigan front end that I have.
A new tire, when measured with the same tread gauge, came in at 8.5MM for tread depth. When I tested/checked at the 10,000 mile mark, I had worn the tire down to 8MM, thus losing .5MM while riding. A bunch of those miles were done while I was not doing much "aggressive" riding as I was still getting use to the new trike, and front end set up.
The last 10,000 miles has seen my trike at places like The Dragon (a few runs), the Cherohala Skyway, Bryson City and the Smokey Mountains, West Virginia, along with simply "enjoying" the trike more now that I am comfortable with it. As such, you can see that the Tread Gauge shows that I took the tire down to right around 7MM, thus took off 1MM over the last 10,000 miles of what I would say is more like my "normal" riding.

In this picture, you can see that the tire still has no real visible signs of getting a "flat spot" down the middle of it, and still has a rounded look to it. You can see, however, that there is just a peak of cupping and I think this may have come about due to my losing a few stick on wheel weights. I plan to add Dyna Beads to the tire soon to see if this has any bearing on tire wear and reduces/limits the cupping. Will know more over the next 10,000 miles.

I took this shot to show just how good the tire still looks at this point. Those that know and have ridden with me know that I am not babying this tire and have really been putting it through it's paces with many different extremes, road surfaces, and conditions. I must say that I remain very pleased with the overall configuration and how the trike handles. It looks good at this point that this front tire may well get 40-50,000 miles out of it. Time and a little more riding well tell.
