By “nine times cheaper,” they mean the fuel for the EV can cost as little as 1/9th as much as the fuel for a gasoline / petrol car.

That’s great, as far as it goes, but depreciation per mile is usually a bigger cost than fuel. Other costs like registration taxes, insurance, and maintenance shouldn’t be expected to follow this 1/9th pattern either, of course. You’re not going to switch to an EV and find your total expense drops to 1/9th.

It feels to me like they’re telling an incomplete story on purpose.

It says “cheaper to drive” not “cheaper to own.”

Regardless, taxes and insurance are roughly the same. Maintenance on an EV is FAR less than an ICE car (no oil changes, fewer brake changes, fewer moving parts to replace over time). So if “fuel” is 1/9, and maintenance is just replacing the tires and putting in new wiper fluid, then driving is going to be much cheaper.

I don’t think they’re actually harder. Stiffer construction perhaps. If the rubber compound itself was harder, you’d be sacrificing grip, which I don’t think you’d want with a heavier vehicle with instant torque up the wazoo.

Quick googling session tells me that, on average, EV tires are a little bit more expensive (~10-20%) due to more exotic compounds used and last a little bit less (also about 10-20%) due to the weight, but they still have fairly soft compounds to retain good grip, which is good news because safety is the last thing you should sacrifice.

At the end of the day, each tire is a compromise, and you simply can’t get similar grip AND better wear AND better efficiency as an existing high-end tire unless you find some truly super exotic compounds, in which case it would have to go up in cost quite a bit.

There are also different compounds for different applications, I very much doubt a Nissan Leaf’s tire is comparable to a Model S P100D so the Leaf may very well have harder tires for better wear and efficiency, but unlike the P100D, you won’t be comparing it to a super soft sporty driving focused ICE tire either, you’d be comparing it with economy tires in an ICE vehicle that will also be somewhat hard.
