There is nothing to stop you putting normal tyres on as long as the meet the weight requirements although they might wear quicker.

No. I read through your link and it's a tyre selling website, they want to make money and the language used is accordingly.
TyreReviews on youtube does tyre tests and EV tyres are more efficient due to less thread depth.
He doesn't recommend them because they are more expensive and wear out faster.
ADAC did a test and has shown that EVs can chew through a set of tyres up to 8% faster but it also strongly depends on the driver. You can rip through tyres even on an ICE car. Heck, the sports tyres on the RS were gone after about 30.000km, they were Bridgestone Potenza afaik.
I have a Renault Zoe (135bhp and 245Nm), FWD and the front tyres were at about 2,3mm after 55000km or 34400miles. So no significant extra wear and tear on those compared to the prior 6 years of driving ICE. They were Michelin CrossClimate+. I replaced them because I got a good deal on a set of Hankooks.
I also had the Michelin Energy EV on my 1st Zoe (90bhp and 220Nm) and they were at the same level at around 40.000km (driven distance) even though I used them only in summer and were rotated each time.
My advice, look on the fuel efficiency label, even though that's another can of worms, respect the weight indicators and buy the ones you fancy. Don't shell extra money on EV-specific tyres because even if they manage a 3-5% better economy it won't pay off.
EDIT: the MG4 has 250Nm torque, even a Renault with the 1.5dCi engine has more than that (320Nm in the 130bhp version).
