My new tires are flat...

That $10 difference could've been the valve stems. The other shops might have it as SOP, while the cheap shop doesn't, "saving you" $10.

I've never heard of a shop that actually cleans the bead seating areas. The first time you do this yourself, you'll be amazed at all the crap in there.

Bwringer is right.

I've had a number of tire changes done on my GS cast wheels in the last 27 years, but no tire mechanic has ever cleaned the bead sealing area on the wheel or even brought the subject up!

So last time I had a tire mounted, I cleaned the wheel myself--and, man, did it need it! It had rubber from the previous tires stuck to it and plenty of corrosion (probably from detergent or tire mounting lubricant) on it, too. I got it pretty nice and smooth with a fine scotchbrite pad and then let my tire guy mount the tire.

Air loss has never been a problem for me because I use a tube in the front "pentagram" wheels, but I wanted to make sure the tire seated in a perfect circle on the rim. I will never have a tire mounted again without first cleaning the bead area.

Both rims are embossed "for tubeless tires", I checked this before ordering the tires. I was expecting (and would've gladly paid for) new valve stems if they weren't replaced as standard during the mounting of the new tires. I'm thinking this may be the problem. But based on the condition of the old tires, and believe me they were bad, I would've expected any reasonable person to install all new components.

when i got my front put on they didnt have any valves in stock suitable
so i had to nip off and buy one
the place do mainly car tyres but the owner rides so they also do motorbike tyres but not as much
i recon if i hadnt gone from tube to tubeless they might of tried to get away with the same thing

Don't worry about it. They're not completely flat - just the bit down the bottom.

It could also be as simple as valve cores that didn't seal or weren't tightened down. (snip)

Turns out the valve core in the front wasn't tightened down. Tightened it two turns til snug and I'm good to go. The rear was fine. I think I over anticipated this one. It was a simple fix. Oh and I like the tires too. \\/
