My 06 LTZ250 currently has super old Dunlop KT733A's on the rear, 21x11.00-9. Very curious about that....they looked like the original tires to me, but O.E. is supposedly 20x10.00-9?? On the fronts, there are newer looking Kenda Klaw XC's, 21x7.00-10. I like the height and the rounder profile of the Dunlops out back, but that size seems to be obsolete. Who is running what on the back of their Z250? Any recommendations for a good, all-purpose tire? Primary riding conditions will be in the grassy field by my house, and my friends property which is grass, and hard packed trails/hills. Finally, would a 20x11.00-9 fit? Those pop up as an alternate size as well. Haven't found many pictures of anything mounted to the machine.
