Flat tyre on a mom's Seat - What should I do?

[threespires]

One of the mom's on the afternoon school run has a red Seat that she collects her cherubs in.

When the term started in the New Year I noticed her right rear tyre looked down on pressure. I mentioned it to her & said that I had a pump in my car & would blow it up for her. Too busy, she said, must rush.

Some days later I offered again with the same reply.
Today, some 3 weeks later, the tyre looked even further down on pressure, I'd guess about 12 > 14 psi.

Could the sidewall be weakened and maybe running hot?
My fear would be having the tyre roll off the rim on a left hander, digging the rim into the tarmac & then what?

Should I point out the danger & insist that I blow it up for her or just ignore it & mind my own business?

Ain't that the truth.

Good on you for trying OP. I sympathise with the tyre fitter who is going to get accused of 'ripping her off' when he tells her that the tyre is too damaged to be repaired and must be replaced.

Thanks --

I blew her tyre up today, it was at 6psi.
PS :- Mom or Mum? I was educated in USA & now I am a Brummy.
