This one seems to be a contentious subject regarding tyre rotation. In the rag tyre days, it was diagonally opposite swap and the worst went to the spare ..... at least that one has been sorted these days because spare tyres are worn by the driver and not part of the vehicle's equipment
With steel belted tyres, direct front to back on the same side, but if the tyre is wearing on the inside more, either front or back, get the tyre reverse on the rim and then swap sides ....... Always mark the tyre with a chalk arrow to show the rotation direction, before removing the wheel from the car, saves getting mixed up part way through if something sidetracks you ..... essential if the tyres are reverse on the rim, really easy to get confused which way it is supposed to rotate when refitted to the vehicle.
Of course, some performance tyres are directional and the case is marked with an arrow ..... unless the tyre is reversed on the rim, it can only be moved from front to back on the same side
Super performance tyres are actually marked as inside and outside, these can't be reversed on the rims, but if you can afford those type of tyres, you should be spending the money to have top notch 4 wheel alignments done regularly ....
