5,000 miles.
Old school Armadillo. 700 x 25 while training for a timed event with 10,000 ft of gain. Heavy stiff wheel used most of the year, many rides through the mountains, local roads, trails, and lot of pathlete miles as well as 30,000 ft climbing every month.
Did 7300 miles that year. Heavy tire but I wore that sucker out till the red strip was showing through but never flatted. Great because I needed something tough to get me through lonely roads.
Wore the heck out of it, then on event day, slapped on a Conti. Big difference but training is training and that tire was tough, heavy but tough!
Usually, a Conti 4000 I will get 2 grand.
