Everyone knows, or should know, the best tires go on the front. Especially on a FWD vehicle.
#1 You don't want a blow out on the steering axle. #2 Front tires typically wear faster. Equalize wear on all 4 tires. #3 Better control and traction on slick surfaces.
Never been in a shop where this wasn't observed.
Now the rotation procedure for non-directional radial tires is open to debate. Although I use the same old method we were taught years ago.
If the results don't match the theory, change the theory.
