Owner -
I am in the same boat as you, but only 2 days in with an ES4 (ES2 + 2nd Battery.)
The tire material for the front wheel is extremely soft rubber as I've been discovering.
Upon a quick "False Start" where i lost traction while balancing + accelerating, the wheel leaves behind copious amounts of rubber into the concrete slab walkway, with no weight upon it at all other than it's own. (I was about to hop on but didn't in this instance.)
All that material shed is not promising for the length this tire is going to last - there must, must be a solution for this beside replacing the entire drive motor, right?
