Wow, you guys must be "spirited" riders. On 2 D402s, I got 15k on each one, 2 up over half the time for each. I agree that stretching a tire on a trip is just asking to get "held up" by who ever has a tire that you NEED that day. Ridding locally most of the time, you can wait just a little longer. And, I believe I read somewhere that the wear bars on MC tires are at 1/32. Car tires are 2/32 unless I am confused.
