Tyre pressure on 24" wheels

lotus49

I recently bought my daughter a Triban Junior for her 9th birthday, which is in a few days. It has 24" wheels,

I'm 6'2" and I like a fairly firm ride so I inflate my own tyres to 100-110 psi. I don't know whether the size of the wheels has any bearing on the tyre pressure but I would guess that the fact that she is quite tall but otherwise fairly normal size would.

Does anyone have any advice on an appropriate tyre pressure for her new ride?

What does it say on the tyre sidewall?

I'd try 40 psi and see how it feels. For the 24 x 1.5" tyres on a Beinn 24 I never put more than 40 psi because their light weight doesn't require it.

You can go a little higher with narrower tyres but there's no benefit in making it too firm - you lose ride quality, grip and feedback on anything but billiard-smooth surfaces.
