Most manufacturers give five years as the max life of road tires, and I for one am happy to take the advice of the folks that make the and know what they are talking about.
The old Anekee one was just a crude T66 four ply off road tire with a fancy tread and was actually piss poor and was replaced buy the A2's which were little better.
The current A3 is a different generation to both and is probably the best 80/20 tire around, with the bonus that they last two to three times as long as everything else except Mitas E 07s
The rules are quite simple if you ride a bike - if you cant afford decent tires dont ride one!
