Some tire shops (at least in my area) are squirrely about putting tubes in tubeless tires so you may have to ask around for someone to do this.
Try to get the oldest guy in the shop and not some bored teenager who has never seen wire wheels and seldom mounted with a tube.
Hopefully you have someone reliable to balance the wheels as wire wheels may or may not require a special fitting to be balanced on the usual machine.
In case this is new to you, a couple of other thoughts: If there are labels stuck inside the tire (can't recall if Kuhmo does that) they should be removed. A dose of talc/baby powder in the tire is good. The way I was shown was to get it all (rim tube & tire) together, inflate the tube, then deflate the tube, then inflate it again. Look at the rubber-like bands around the inside of your rims, they should be in good condition (they protect the tubes from the ends of the spokes). Replacements are available though some just use duct tape.
