I took in a customer's WH-7900 C24 wheels. They're tubeless spec.

I took them in to check both front and rear wheels for runout and centering,
but given how long they've been in use, there was almost no runout at all.
（I forgot to take photos, but）the front wheel especially barely needed any work.
The rear wheel had a slight centering issue, so I corrected it.

Normally I'd remove the tire to do runout correction work, unless it's a tubular tire,
but this time I did it with the tire still on.
The reason being that the radial runout looked nonexistent, the customer mentioned sealant was inside,
and the hassle of resetting the tubeless tire bead back onto the rim... those aren't the reasons.
I checked the centering with the wheels at their normal riding air pressure.
Why I did that—I may never be able to write about it here.
