Why can't I get the tubeless tire off the rim?

There could be several reasons why you are having difficulty removing a tubeless tire from the rim. One common reason is that the tire bead may be stuck or sealed tightly against the rim. This can happen due to the build-up of sealant or dirt, or if the tire was not properly seated on the rim. Using tire levers or a tire bead breaker tool can help loosen the bead and make it easier to remove the tire. It is important to be careful and patient when trying to remove a tubeless tire to avoid damaging the tire or rim.
