this set has around 2000 miles on them. they're currently fully inflated(this is only the rear) and have been ridden in the last day.

these tires take an absolute beating and come back for more. i weigh around 200#, too. they were brand new when i got the bike in April of last year and even still have some of the little nipples hanging on. i do have a replacement tire on hand, so no worries!
