Will I need a new tyre? Accidentally parked car with half-tyre on the kerb.

To be fair to the OP I have friends who think the tyre pressures are something they do on the annual service! I wish I was kidding. So 3 months is probably regular by comparisson to the average joe.

Everyone knows what you're supposed to do but to be fair, I never check mine and I suspect most people don't either. I've never seen anyone in my street out there checking their tyres.

A quick glance round now and again to see how the tread's going and whether they look a bit soft and it's job done unless the TPMS flags a fault.

Never? You should check at least once a month. The TPMS warning isn't a substitute for checking tyre pressures.

ideally you should check every week (me sunday) this is my routine

1. Make hot coffee
2. Go out check oil (top up if needed)
3. check anti freeze (top up if needed)
4. check screen wash (top up if needed)
5. check other levels (same as above)
6. check all 4 tyres with psi reader (add more air if needed)

7. Go back in and enjoy your coffee thats cooled down lol

ps: i know someone who was driving around with 2 bold tyres and 3 months out of mot and yet they complain when the car breaks down erm... ok

You forgot:

Back to the original post. It is highly unlikely that simply parking half on and off the kerb will cause the tyre to leak, however, I guess that a hard strike at the right angle could temporarily break the seal and cause a problem, though I am struggling to convince myself that it could re-seat itself afterwards.

A couple of causes are that a tyre may be slowly losing pressure and what does happen is that once they get below a certain pressure they lose their shape and are more likely to not be well sealed and the pressure drops more quickly.

Most likely the tyre has a slow puncture, or a poor rim seal (corrosion on alloys can cause problems) and the tyre has been going down for a while and the kerbing has simply made you look - a coincidence). Tyres get a real hammering along a typical road surface (think of the forces involved in hitting a poor bit of road surface on the motorway at 70mph, or cornering on an A road where the car is near the limit of grip) and then consider the forces of simply riding up a kerb and sitting there, you'd have to be looking at a high kerb hit fast to really cause problems.
