On non directional tires do you guys cross rotate or go front to back? My Revo 2' s have been balanced and the alignment is good but for some reason the left side tires front and back seem to be cupping, the passenger side seem to wear pretty good.
From what I've heard....from Tire Kingdom.....is that with steel belted radial tires all that is needed is a rotation from front to back and back to front, on the same side of the vehicle.
They stated there is no reason to cross rotate the SB Radial tires.
I cross rotate front to rear, rear to front straight. After 4 rotations the original wheel came back to original position, I think that way all 4 tires wear evenly.
When to cross depends...
primarily on how much torque steer affects left front tire wear....if there's little torque steer wear on that tire then straight back is fine...but...
If, as happens on MANY cars (kitcamry being one), that torque steer makes the front left tire wear more than the others, (a result of that wheel pushing/"torquing" the car to the right under heavy acceleration), then cross it over to the back...that will more quickly even out the wear ON THAT TIRE...taking it straight back will likely make that tire wear more, and more quickly, especially on the outside sidewall.
...a car with torque steer will need MORE FREQUENT ROTATIONS to prevent THAT LEFT FRONT WHEEL from wearing out tires too quickly...
On non-directional tires (like the Firestone Destination LE2's on my Dakota) I cross the left front to right rear and right front to left rear. I move the rears to the fronts on the same side, left rear to left front, right rear to right front. That is how I learned it from an old-timer long ago. It helps avoid any pulling to one side or the other.

Add 4-5 pounds of air to the tires,
push the center out.
Do not exceed max pressure listed on the tire sidewall...
I can't tell from this post if you're aware that cupping is different from normal accelerated edge wear from under inflation. Cupping is a type of uneven wear on the edge of the tire.
If you are aware of the definition of cupping, then you're proposing a solution I haven't heard of before.
