thats crazy, because i've run over 2000 miles on my DT (which is heavier than a moped by a good margin) on a 17x3" gazelle. Almost all those miles between 45-55 mph. It has little to no evidence of wear.
last time i had them on a moped i probably put close to 3000 miles on them with minimal wear on a 2.25"
every time the threads come up, i ask what is the 'better option' for all-around daily driver tire and there is rarely a consensus. I hear those Deestone world traveler are good, but they don't look like they have a profile to them so they would probably handle like a B8 or kenda 188 or whatever.
i'm all ears to try another tire, i'm gonna get some of those K56 hidenau for my tomos, but for a daily driver i'm just not seeing anything else on the market that looks good. Schwalbe?
