I suspect most damage is caused to low profile tyres with the wheel rim also vulnerable.

I would go for higher profile ratio which will allow for more tyre deformation when mounting the kerb without damaging alloy.

Putting things in a public road is probably not sensible - aside from the theft risk, you would be liable for any consequential trips, accidents, incidental damage.

You are right of course in that something with a taller profile tyre would be preferable. Not that easy in practice though. An auto will generally means a higher trim level, which in turn generally means larger diameter wheels on lower profile tyres. I had quite liked the look of the Fiesta Active which has a higher ride height and crossover styling cues, then I learned that it uses 205/45 x 17 tyres!

The Ignis runs on 175/65 x 15's (plus it only weighs about 850kg) and my Caddy van uses 195/65 x 15's.

Quite liking the idea of the triangle section post though!

Whatever is done, I would ensure the tyres are kept at or just above the recommended pressure.

This basic requirement is essential for those with low profile tyres who encounter potholes to minimise the risk of expensive wheel damage. You can appreciate the minimal resistance and protection offered by low pressure by squeezing a bicycle tyre inflated to a mere 30 - 35psi, a pressure range normal for many if not most cars.

I made concrete ramps which are removable, nobody seems to mind, not even the council sweeper thing when it comes round. But I live on an estate not a road. They don't stop water flow at all. Car wise, how about a Sandero stepway, Duster, or a Vitara? They are not very big. What about another Ignis actually?

The list of cars available through Motability changes per quarter, some cars remain on it, others vanish without a trace!. Up until I had resigned myself to mounting the kerb, I had discounted the Sandero Stepway, Duster and indeed Vitara because I was looking for something no wider than our Ignis (or the Jazz which preceded it, both just under 1.7m), but since then, yes. Problem is the Sandero Stepway is not currently available as an auto through Motability (it was last quarter, with a £300 advance payment). The Duster is available, but with a £3800 advance payment(!), and a Vitara is also available, with an £800 advance payment, but it has the same type of auto (the dim witted and ham fisted AGS) as our Ignis. I'd have a current Ignis auto (which uses a CVT these days) in a shot, but it hasn't appeared on the Motability list these last four quarters (ditto the Swift).

How about a fiat E500 as a next car? I believe motobility currently have some good deals on them.

That may have been the case during the last quarter, no E500's this one (not according to the Motability website anyway?). But it isn't big enough in terms of rear space anyway. The Renault Zoe is though, and is currently available with no advance payment. That is giving me pause for thought and making me think about how feasible it would be to run an electric car without my own off street parking. Ignoring that particular stumbling block, it is just about ideal otherwise being tall (better for my wife, and my father, to get in and out), 5 doors, enough space for 4 adults, decent sized boot and although wider than the Ignis, is relatively slim hipped compared to most. Tyres are 195/55 x 15, not as tall as I'd like but not too bad, and the WLTP range is 238 miles. Haven't checked, but I doubt we've done much more than 10k miles in the Ignis since we got it about the beginning of June 3 years ago, so I'm fairly confident I could manage with the Zoe's range.
