Rear-Wheel Steering's Impact on Tire Wear

[The Critic]

Recently purchased a new vehicle with Rear Wheel Steering. I plan to rotate the tires every 5K, but am curious how this system will impact tire wear.

Does anyone have experience with rear wheel steering systems?

That's an interesting question.

If you move a wheel to the rear to even out wear, but the rear wheels steer ... what's the factory rear camber setting? Is it closer to 0?

I think like anything it depends on the system and what is was optimized for.
In general I would think tire wear is more even between front and rear, because A) you have rear tires turning, but also B) turning should be more effective with less wear on the front.

Any independent rear suspension will rotate the rear tires in yaw relative to the body structure as it compresses and extends. It's not a whole lot different than having a dedicated rear steering system.

except modern vehicles hardly roll.

Even if a vehicle has so much roll stiffness that it squats rather than rolls, the weight transfer to the outside will still amplify any toe changes on the outside wheel more than the inside.

we're talking fractions of a degree, not multiple degrees like 4 wheels steering and the rear wheel steering can go toe-out on the outside rear wheel, aswell as toe-in in the same corner.

Mmmmmmm. Bring these back

The tires, Michelin makes them in their Classic line: https://www.michelinman.com/classic/tires/michelin-mxv

But the car, i think Honda didn’t import the Prelude 4WS in significant quantities.

My 2003 Sierra Denali pickup truck had rear wheel steering. I continued to rotate the tires every 5k just like all my other vehicles. It’s funny but the thought of rear wheel steering making tire wear any different never occurred to me lol.
But in the real world the rear wheel steering made a big difference in the way the truck drove. Easy to turn around at low speeds as the rear wheels turned opposite of the front. The big difference was on the interstate when all four wheels turned the same way. You literally felt the truck just go to the other lane with no yaw forces. Felt like just stepping to the right or left.
