It may come down to driver style and circumstance. I have a couple of routes to work and the one that is mostly dual carriageway has one section with 7 consecutive sets of lights so lots of regen braking and accelerating. I was definitely playing a bit to ease the boredom and would rarely let anything lead me away from the lights. As a result the rears were not going to make 10K miles so I've just consciously altered my driving to either match normal traffic or follow cars on left lane.
The i3 only has a choice of two tyre makes being so tall and skinny so I'll switch from Nangkang to Bridgestone to see if that makes any difference.
Yeah previously I kept tripping the traction control light and not just pulling away from stop. So I've modified my driving style and have gone from 4.5 mi/kwh to 5.1 mi/kwh on my commute. Mostly dual but no faster than 60 mph which is fine for a fairly short 18 mile commute route each way.
One common gripe on the i3 is the over sensitive pedal when in comfort (call it normal) which is the default mode when pressing Start. The ECO PRO mode is just a more pleasant way to drive overall so it's second nature now for me to press Start and then the mode button.
This is how I burned through tyres. 0-60mph dual carriageway traffic light GPs. My commute has loads of opportunities for it.
