the best wheel rotation is every 10KM
then four tires  will last longer and well maintain.
cost not much only alignment and balancing

Yes, best if do every 10k km. But alignment and balancing is not a must, can test first then only do if necessary. Balancing will only be required if you did on-wheel balancing or if you need to dismantle the tires from the rims for rotation (switching left/right for directional tires), otherwise no need.

i practice it before when it is very new, but then after some times, from 20K km to 30K km.
lol.

Whoaa 5k is too frequent leh!    But very good lor, your tires will always be very even and maximum lifetime!    Me, I just do every 10 or 20k km depending on whether I use asymmetric or directional tires. If asymmetric and all same size then I rotate every 10k km coz it's easy. If directional or I'm on staggered sizes then I just do every 20k km coz need to dismantle the tires from the rims.

Wow, 5k km once to rotate? I really salute u bro..

bro
you are very sayang your tires
