Yesterday, I wrote off an otherwise perfectly good 225/45x17 tyre
because I had apparently been driving it flat for a while without
noticing.
In days of yore I could always tell by the seat of my pants if a tyre
was a bit flat. But many modern cars are grossly over-tyred, with
very wide low profile tyres which *look* flat when they're not, and
don't really *feel* any different when they are.

At £100 a throw, you don't have to write off too many tyres before a
monitoring system would be cheaper.

Any comments or recommendations?

How about manuall checking your tyre pressures weekly, at the same time as
you make all your other routine checks?

You do make routine checks don't you?

Must be "very" low profile if you can't tell the difference when it's
flat .

The rear Bridgestone tyre on my Honda (also 45 profile) didn't look
flat but had no pressure at all. The sidewalls on some tyres are so
thick it can be hard to tell.
