i replaced the rear D222 with a ROADSMART 2 @ 8500 miles, then replaced the front D222 with a ROADSMART 2 @ 10,000 miles. I am coming up on 20,000 miles now and will be swapping both for ANGEL GT's in the next month as i am about to hit treadwear indicators on both front and rear. i average around 1000 miles per month and the last 10,000 miles on the bike have been about 50% canyon carving and 50% running around doing errands so YMMV.
