I see a set of new tires in my immediate future and am needing to be as frugal as possible right now. I checked the date codes on my current tires and it scared me half to death (believe me - you don't even want to know!). I know that some POGers like the Double Coin tires and I've seen you say that they are much less expensive than the Michelin XZA1's. Could one of you Double Coin fans tell me which Double Coin product to consider for my XL45? I'm nervous about switching from the Michelin product, but may be forced to let economics dictate my choice. What say you?
