One point about tire rotations.

If say one started with four brand new tires and they were rotated at
10,000km. Then the next rotation will be logically at 30,000km because at
20,000 the fronts in a FWD vehicle will have worn to be equal to the rear
now and since they are equal, why rotate? (They should be the same as the
first 10,00 the fronts which are now the rears got worn at a faster rate
than the back, which then got rotated and now the rears which are in the
front have worn by the same amount, assuming same driving style)

Is this logical to you guys? But almost all tire care guides will say rotate
at every 10,000km
