Alright. I really do need help finding tires. 3.25 x16 front and rear. Plenty of fronts, no rears. One guy on ebay selling a set of Shinko tires that'll fit - except he doesn't seem to want to reply to my question about load rating. I thought to ask because a lot the Shinkos I've seen that would fit are actually moped tires with a ~400lbs load rating, which is about what the bike weighs. What are the consequences of running a front tire in the rear? edit: discovered the shinko part # (thanks google). Shinko SR567. Shinko lists this as a moped tire, but I have seen it advertised as a motorcycle tire too. I just can't seem to find a load rating anywhere. Can I make a 100/80-16 fit? and am I right thinking that 3.25 is just about 100/90 ?
