That picture looks like the front 021 that I gave away yesterday with 1,400 miles on it! What a piece of junk! The rear looked fine. But either way, changing to other tires makes a major difference. I have no idea how people get any kind of miles on these tires. My C14 front was toast at 4K. The rear almost worn out also.
The FJR front was significantly worn and pushing bad at only 1,400 miles. The 021 front is junk! But I will agree that the rear seems OK. But still wears quicker than most tires. I would never use these ties if I didn't have to! And it's beyond me how someone got 13K out of one!
