Pumping trainer tyre... How often?

[Sjw]

So I was pootling around off road just now (i pootle, I don't race) and my watts were about 60 which I'm used to but trainer tyre seemed sluggish. So I pumped it up to 100 psi and power shot up to over 100 watts. Also I seemed to be a bit faster.I
I still don't get the power/watts thing but I'm aiming to get on the trainer about 5 times a week.
Anyway, waffling on, how often to pump the tyre up? I've only done it twice in 3 months ....

Lower pressures lead to higher resistance

If you are talking about on a turbo trainer then tyre pressure is critical, I would be checking twice a week

Thanks for that! Bike seems happier and I'm going further faster, though still stationary, but I know what I mean!
I'm doing more inclines, can't call them hills, and it's not hurting as much.
Will be checking that tyre regularly ... must look at cars' too!

Pump tyres before every ride.

Just part of the routine for outdoor riding, so I do it for indoor too.
