Yup, that is the way for 2 tyre change format.....well.. usually rear tyre is OLD but still got plenty of thread left....
so thats where i begin to put new tyre at rear tyre...and use older in front....
since FWD is faster wear infront... hence...old front will fully utilized...then when it time finished all the front thread...
buy new tyre and put at the rear again....
older rear which was previously was new then relocated to the front...
and the cycle continues....
