For those that don't know me, I just got into this sport, so please excuse my ignorance. So, what are the best tires out there for the 426? I typically ride in moderately soft terrain, but occasionally on hardpack. Is there a decent intermediate tire? The aftermarket parts store by me was recommending the Dunlop 756, but I read that is only for soft terrain. Will it hold up OK if I use it on hardpack once in a while? Thanks.
