Re: Rotate tires?
Not to extend this argument an further but it's not actually the direction of rotation where tires can take a 'set' but it is actually the direction of load. Drive wheels spend most of there time loaded by the drive and non drive wheels are loaded by the drag. Hence, on an AWD you would rotate the tires from front to rear and on a 2WD or occasional use 4WD you would rotate the tires diagonally but not front to rear.
Also if you have directional fine siping on a ice tire which is marked in the direction of rotation it works better if the direction of rotation is looked at as load so on a FWD the rear tires should have the tires mounted backwards. This does not apply to summer, rain, or all-season tires as the directional arrow would apply to water extraction which is not affected by load and only direction.
Very high performance tires are more affected by a change in the tire loading than regular tires so for most people none of this is an issue. Also, the same issue used to apply to extreme performance racing tires that were bias ply, as with radials, as they were pre built with a directional 'set'. In any case, none of this applies to a boat trailer tire, bias ply or radial, as they are basically just there to stop the wheel from hitting the ground.
