I have a wheelbarrow with a small car-type tyre.

The wheel has gone flat - has a puncture.


You can do it with a spoon or fork. Your wheelbarrow tyre is(should be)
just a fatter yet smaller diamater cycle tyre. Not much psi. Not a car
tyre, very far from it. Just looks like a car tyre. That is where the
similarity ends.

Have you ever actually looked at the pressure on a pump fitted with a
gauge when inflating a bicycle tyre or are you just guessing?
Even one at the low end of Bicycle tyre pressure ranges at about 40
psi is getting towards the higher end of car tyre range and that'll be
on reasonably wide tyres fitted to mountain bike types. The thinner
tyres used by a lot of people on sportier type things will have tyres
inflated around the 70 to 120 psi range. Far higher than car tyres or
indeed wheel barrow ones which be around the same as car tyres in the
30 to 40 psi range. Inflating a wheelbarrow tyre to the majority of
bicycle pressures could risk either injury or being sued by James
Dyson for infringing his patent for the Ball barrow.

Perhaps he did it accidentally and got the idea.
