The problem is that for any puncture that can't simply be re-inflated
withot sealant for long enough to complete the journey, I have never
found sealant to work at all.

I really don't get it. We run Punctureseal in nearly all our vehicles
(cars, vans, motorbikes and trailers) and can't say we really worry
about or suffer from punctures?

We know it works (and Ultraseal before that) because we have used it
retrospectively and it has worked till the tyre was replaced when it
was worn out in *all* cases.

The only time(s) is hasn't is when people have pinched the sidewall
against a kerb and bitten a 5p sized hole out of the sidewall (and it
wouldn't have worked there no matter the size of the hole).

We carry a spare with all the vehicles it's practical to do so with
(cars, vans and trailers) because 1) we always have done and 2) there
will always be those instances where the sealant cannot work (as with
the examples above) and / or the rim itself becomes damaged (potholes
and the like).

I guess it you were changing tyres regularly because of high mileage
then I guess it could be 'expensive' but then for what it normally
costs to treat 4 tyres, divided into those miles and the convenience
of not having to 'suffer' a puncture, it might be worth it for even
stopping one puncture per set?

YMMV etc.
