How important are the tires? The only couple of times I rode in the rain, it was a relatively light rain both times, and I still felt like my rear end was water planing pretty bad. As a relative noob, it scared the hell out of me. I've since purchased new tires, but not really ridden in the rain on them, but I've also read in other places that the gz250 is not good in the rain generally. What do the veteran riders say?
