Lots of people buy used tyres on eBay, i used to buy them on there to use as track tyres as you could get some really cheap if they were collection only.
EV general discussion

Was going to say, probably the best bet compared to ebay or local marketplaces for not dealing with hassle / people trying it on. But most people just shift them on ebay.
If we were talking in wheel motors then sure but not with the cars currently on the road.
The power will go through a differential, same as on an ICE, there is no magic involved with an EV in terms of the power getting to the wheels.

I have now long term owned or leased 5 EVs since 2020. Absolutely zero difference with tyre wear on the EVs and that included heavy SUV types.
My I-Pace got a set at just under 3 years old and with 27,000 miles on the clock. Our C40 had one set of fronts changed at 18,000 and my Born got a full set at 28,000 but could still have went another while with 3mm - 3.5mm tread left. E-Tron was two year old and 17,000 and never needed new tyres when the lease ended.

The differential is only one part of the equation - on my ICE Qashqai for example Intelligent Trace Control uses active small amounts of per-wheel braking whereas on the EVs it uses modulation of the motors to much more fine tune power delivery to the wheels increasing power or reducing torque using the motors instead (and thereby often avoid the more abrupt later reaction using brakes).

Sure, though that depends on the model - some EVs have dual-motors and/or varying AWD implementations. I'm trying to generalise a bit as the specific implementation will vary. But often EVs can use the motors to avoid the situations where an ICE will have to resort to the brakes and/or mechanical lag of an engine.
EDIT: Though the main focus of my thinking has been relevant to the Nissan e-4ORCE implementation.

Sounds like a clever system but the net result is the same as an ICE 4WD with an active centre differential. Unless I'm missing something
Proper TC intervention sure - but most modern cars use small amounts to improve ride comfort, handling and safety.

Even with a differential in the equation what is actually delivering the power makes a difference in response along with the EV's ability to use regen to reduce torque without using the brakes.

When? Are you getting confused with ESC which might brake inside wheels.
Not sure what you mean about ride comfort improvement with TC
Engines can cut engine power pretty instantly and rarely use brakes to try and fight an engine. Not sure where you are trying to go with this. Theres so many different types of systems with different programming etc that I don’t think you can just do ICE vs EV. Modern ice TC systems are very good.

No just generalising rather than specifically mentioning ESP/ESC or TC. My original comments weren't so much about whether one is better than the other but that the approach EVs use for ESC/TC tends to slightly bias the wear to the tyres rather than brakes overall.

My local BMW dealer (Chelmsford) has the new iX3 in from tomorrow evening and all day Tuesday, so if I get a chance I'll get there and maybe grab some pictures.
Pls put them in spoilers. Don't want to vomit when I open this thread
I’ve seen a black one recently and it’s a nice looking car. Far nicer looking than most of the other stuff they have been doing with the iX for example.
This evening I signed up to EON next drive in prep for the EV arriving in the next 2 weeks. Beautiful graphs showed me I would be saving about £150 a year. 7.5p off peak for charging. Looks great - agreed to switch.
I then look at the detail. Whoops. It assumed I am now living a nocturnal life. My energy usage has been assumed to be 50% peak and 50% off peak with a hefty increase in peak rate from 23.51p to 33.95p (!). Aside from putting a timer on my dish washer, I can't see this being cheaper. In fact it'll cost me significantly more.
There is a 14 day cool off and I'm now looking at EDF which offers 28.75p peak and 8.99p off. Am I missing something here ?

Thought this was interesting, i mean its exactly as you expect but interesting to see real world numbers and times applied to it.
Edit: at least 50% off peak assumption is realistic.
8000 miles at 3miles per kWh after charging losses is 2666 kWh plus whatever your household usage is in that period. Don’t forget you can run your dishwasher etc overnight to benefit from the cheap rate.
That said octopus is cheaper at 8.5p off peak and 29p peak.
