Rear Tires Wear Faster

[Vettepartz]

My Tesla has the duel motor setup. One motor in front and one motor in the back. Obviously, the software has to keep these in sync so that one is not pushing or pulling against the other. I think that would be a bad situation.

So my question is this: If they are running in sync, why do the rear tires wear out faster than the fronts? There must be other factors involved here.

I have Model X and Model 3. Both are AWD. The Model X tires wear pretty much evenly as you can't even rotation the tires because front and rear are different sizes. For the Model 3, if you don't rotate the tires, the back wears out about 3x faster than the front. I don't know why either. I think the Model 3 (and probably same for Y) just put more torque in the rear wheels.

I suspect a bad alignment, such as too much Toe out.

Most of the time, only the rear motor is activated. The front motor is used during strong acceleration or when the rear wheel are spinning.

If you have an ODB2 App, like Scan My Tesla, you can check when the front motor is used.

Also the weight shifts to the rear when accelerating

rear motor bias. Rear motor is often working harder and providing more acceleration than the front.

Both of the above posts. It is my understanding that the front motor only engages under (almost) full throttle.

However, IF the OP has "duel" motors, maybe they ARE fighting each other????

Now I get it - the other meaning of "dual". LOL

From what I understand the rear motor is more efficient than the front motor so it’s used preferentially.

@Vettepartz not quite. "Dual" vs. "duel" (dual vs. duel on Vocabulary.com).

The two words are homophones of each other. (Homophones, Homographs, and Homonyms)
