No knowledge on those specific tyres, but some general points/obseravtions.

Re other tyre sizes. If sticking to the original wheels, while in theory you can choose a different size, I'm not sure there would be much benefit in price or ride comfort. The need to keep approx the same circumference for speedometer accuracy and gearing, along with having to fit on your wheels means the "smaller" tyre wouldn't be much smaller (and therefore probably not much cheaper. Using a comparison tool, I see 215/45 x 19 has more or less the same circumference (+0.8%).

If changing to a smaller wheel, you have more options which would mean cheaper tyres offering better ride comfort (but you would need to ensure adequate clearance over brake components) If going down an inch you could use 215/50 x 18. If going down another inch, you could use 215/55 x 17 or 235/50 x 17.

But I also can't help wondering, given you seem to be describing it as both rusty and a bucket, whether you should be either driving it hard or spending circa £1000 on premium tyres for it.

You also don't seem to be aware of the fundamental contradiction in looking for tyres which provide maximum grip/roadholding and offer a long life. High performance tyres by their very nature are going to use softer rubber to provide maximum grip, which is obviously going to mean a higher wear rate. If you want a tyre which is going to last as long as possible, you need to be looking at tyres which are not so performance orientated, but also you need to be driving in a more sedate manner when it comes to acceleration, cornering and braking.

One other point is that if changing from original tyre size, you should inform your insurer.

It is hard to advise you as we don't know where you are. Tyres will wear differently in hot climates and or desert conditions. 100.000 what ? if your car is typically 30% dearer wherever you are, maybe tyres etc are dearer too.
