I'm gonna replace my tw 52 rear with a more street-type tire. The stuff I'm seeing about the shinko 700's and 705's on other bikes makes me think they are worth a shot. I'm looking for speed / load ratings on the 700's... but in the mean time.. just wondering if anyone here has mounted the 4.6x18tt or 5.1x18tl tires on their xl. Or, the 130/80-18 705. Fit issues?
