Those wheels don’t rotate front to back right? Even wear on the front and back tires? Did you get the dual motor 4 wheel drive version?

In the early models, with the staggered wheels, there were literally four different ones, so even discounting the F/R size differences, you couldn't swap them side to side either (and, the tires are directional, too). At least with the winter tires, you can swap F/R, but would have to remount them to swap sides so that the rotational direction was correct. FWIW, when they were delivered, the set had all mounted for the left hand side! Before I could take them home, the dealer had to swap two of them (came direct from BMW that way).

Wider tires are more prone to aquaplaning, and, if all-seasons, in the snow, won't have as much traction. Some cars give you lots of options, the i3 was optimized, and those options fell away without more changes.

Early BEV's (2014 - 2016?) with the 19" 427 pizza wheels had the same wheels and tires front, back, and on both sides, so its tires could be rotated conventionally.

An i3's summer and all-season tires are not directional like some winter tires, but they do have an in side and out side. This means that the wheels could be moved side-to-side without remounting the tires.

Because in 2015, BMW started mounting the same wheels on both sides of the same axle, the rotational direction of the wheels must not be crucial. Therefore, I don't think rotating side-to-side would cause any problem and would tend to equalize rear tire wear since the rear tire on the passenger side seems to wear faster than that on the driver side.

So, it seems a sensible starting point would be to know the weight of each model of the standard wheels, and Tyres. I have not been able to find any stats apart from a 429 19” rim being reportedly 8.4kg.
Does anyone know what the standards weigh?

I paid for a four-wheel alignment about a month or in the first year so we're still using those settings.

The results of your earlier alignment experiments seem to be working well. Please remind me what alignment settings you are using.
What is more remarkable is last Fall I had sidewall damage on the right rear tire so it had to be replaced. In effect it looks like no measurable wear (or someone didn't really do the measurement.) After finding all the error codes in the vehicle logs, my bet is on sloth over malice.

So did anyone ever experiment? I think there are setups that theoretically work. We understand the BMW “optimal” choice is on the car already, but it would be nice to have more options and I’m not sure what difference some combos really would make. If it’s 50% loss of range, ok, not so good. But some of us would trade 5% for more grip and more options.

Anyone actually try anything different yet?

I read a recent article saying that Michelin, among others, were beginning to develop more tires for EV's. The article specifically called out the greater weight and starting torque as challenges for EV tires (as well as energy efficiency). So, perhaps there is hope for another manufacturer for tires for the i3. Getting to be more than a few on the road in Europe.

As far as alternate tire choices, there actually are a few, just for the most part not offered in North America (allthough the US is the biggest market for the i3?!)

Here’s the link to the 155/70/19 (selected through the vehicle menu, these are intended for i3) choices on Germany’s biggest online tire dealer:

while the US online shop of the same company (Delticom) shows nothing but the usual suspects:

I would love to add more rubber (taller tire) for the comfort and other tire purchasing choices. I don't care about the width but something that isn't as low a profile as what we have now. If you use tire rack's tire comparison tool, it will show you what brands and tires are available in the different sizes and configurations.
