5 wheel tire rotation
#51
So why does it need to be different for two vs rear or four wheel drive? Because the only thing I can deduce from comparing both diagrams is that when a tire is moved from an axle which provides the power it goes to a side of the car in which the tire rolls in the same direction as it did. But eventually all rotate diff directions. Puzzled why it matters...

Are there any problems associated with running unidirectional steer tires with one going the right direction and the other going in the wrong direction?

Thank you for this opportunity to be of assistance.
When dealing with medium truck tires:
Uni-directional tread designs are used primarily to maximize irregular wear resistance when the tires are at their maximum, or close to maximum, tread depths.
Although there may be some very slight differences in wet pavement traction, the only noticeable drawback to running one tire in the indicated direction of rotation, and the other tire in the opposite direction, is that when a uni-directional tire is run "backwards" early in its life it will be more susceptible to the development of irregular wear patterns.
Once the tires reach a remaining tread depth of 13/32nds or less, in order to simplify steer tire rotation, it is acceptable to run the tires in the opposite direction from that indicated on the sidewall, (however it is recommended that both tires run the same direction.) This is because the tire is less susceptible to irregular wear as it wears to shallower tread depths.
Please keep in mind that this applies only to medium truck tires.
Passenger and high performance light truck tires often have far more aggressive uni-directional tread designs than do medium truck tires, and thus running in a mixed or opposite direction of rotation may result in very discernible traction and/or handling issues as well.
Best regards, Tire Doctor

Having read through this thread I am a little confused...
Have we concluded that uni-directional tires should not be cross rotated because they will wear unevenly?
Does "uni-directional" refer to "Radial" tires?
--
I have BF Goodrich Mud-Terrain LT255/75R17, so I have radial tires; how should I rotate my spare on?
I was thinking of putting the spare on the rear right, moving the right rear up to the front right, and put the front right on the spare.
Feedback?

Directional tread will wear evenly rotated in a cross pattern but performance will be substandard possibly to the point of being dangerous under certain circumstances ie a rain tire at 100mph in the rain sucking water to the center of the tread rather than pushing it to the edge. Directional does not mean radial it means the tire has a specified rolling direction noted on the sidewall due to tread pattern.
Asymmetrical tread is different but not directional. It just means that the tread is not the same left to right when viewed from the top. Rotational direction does not matter on these and can go either right or left and once mounted can be rotated as regular tires.
