Shinko Sr567 120/80-14 58S Front

I have had good wear from shiniko I bought bikes (been riding for over 45 years) with other brands the last shiniko I bought was to replace a dunlop that had probably another 6 months of usable tread life but the tread separated from the cords of the tire structure & got a bubble in tread wear part of tire about the size of a lime but the scarier thing is it would seem to move from the left side to the right side of the tread pattern (weird right) but anywho shiniko has good wear & last long time the last probably at least 6 cm tires I bought have been shiniko & this is second one this year this was for the front wheel & I put one on the back about 2 months ago ..... I will continue using shiniko barring any changes in quality & price
