How should I rotate my tires when front and rear tire sizes are differant

Tom in Austin

Can'r rotate between front and rear and if tires are unidirectional, can't move between left and right without taking the tires off the rims and turning them around. Practical effect of this is no rotating, you just replace in pairs as they wear out. This can be a nuisance on cars like my Porsche where the rears wear much faster than the fronts.
