Might be tubeless. I'd think your mechanic that put the tire on for you will know. So that's where you really need to get the information specific to your wheel and tire from since we can't possibly know for certain what he or she did.
If it is tubeless and your tire beads came off the bead seat, then you will have some issues unless you have a very high CFM coming from your pump/compressor and through the air chuck.
Might suggest you try a CO2 inflator if you for some reason don't want to go back to the shop.
