Yea after I replied I assumed that was your situation.
After I punctured the Michelin Tracker on a nail on the first outing, I opted to replace the tube myself at home. I learned how impossible it can be without tyre lube - especially when you pinch the spare. Once it was fitted I got Bike-Seal put in front and back to hopefully avoid knowing that pain again.
But yes you are right, the tubed tyres have a more traditional bead shape compared to the tubeless. I watched the mechanic use a compressor to seat a couple beads and it needed crazy-high pressure to pop in place properly.

Managed to get the rear on but resorted to the compressor again. After the beads seated I thought it would be a good time to read the warnings and instruction sticker! Turns out 57psi is the max and they like you to have the wheel strapped down and a remote way of operating the air supply. I wouldn't be typing this now if it had exploded obviously :)
I'm going to have to do some research on how to handle this at the roadside but I will guess that new tyre beads are harder to seat. I cleaned the inside of the rims but it didn't make the job easy enough to do first time.
I was mistaken about the tyres though, they are in fact rated for tubes.
I think it's a job everyone should do once, nice to learn a bit about such a basic bit of bike engineering.
Airhead
Yes, but it's a bit more complicated because the wheels are rated for tubes but the tyres are tubeless. Because nowadays no one makes tyres for tubes. Some people run them without tubes but I've never had any luck with that because the holes are not made for the standard valve and I've not gone as far as drilling them out due to the design. The discussions on this subject have been going on for a long time in airhead circles!
But basically, yes, I tried inflating with a a track pump to around 40 but it needed 60 with the valve out on a compressor and plenty of lube. I will try with the valve out on a track pump and go a bit higher on the pressure when I do the rear later today.
I'm guessing motorcross tyres and rims are built for tubes so have a different shape or I need to do a better job of cleaning the inside of the rim.
