I tried the Avon Trike tire starting with 4,500 miles on my bike,,, pulled the avon trike tire off 2 days ago with 13,000 miles on the trike..... 39lbs of air cold and ran 2 oz's of dyno beads.... thats only 8,500 miles I got out of it,,,,I live in NW ark like someone else says,, these roads around here made of chip and seal will kill the life of a tire,,, and it did mine....
