I got a new road bike with tubeless tires. I can't get the back tire to hold air. I got the front tire inflated but for some reason, as I am pumping the air all I hear is it coming out somewhere from the tire. I don't see a hole. It was shipped from another state and it came completely flat.

There could be many causes for a flat tubeless tyre, especially on first installation.

1. Check the tyre is actually tubeless compatible


2. Check the tyre beads are seated the whole way round


3. Check the nut on the valve is tightened (finger tight)


4. With the wheel off the bike, shake the wheel and listen for sealant.

If any of these conditions are not met, rectify the problem before trying again.

If they are all met, then you have a hole in the tyre - not at all unheard of in tubeless ready tyres which are designed for use with sealant.

To find the hole, get a helper to operate the pump for you, whilst you carefully inspect/listen to where the air is escaping. Whilst still pumping (to generate some air pressure), rotate the wheel so the hole is at the bottom. This will cause the sealant to pool in that area and plug the hole.

  On my first tube less setup I couldn't get a seal at the valves until I deburred the valve hole and added duck tape to the rim tape. (The duck tape did not last long though, the sealant fouled the adhesive.) A few drops of sealant at the base of the valve stem helped to revealed that leak.

Tubeless tyres hold air only after being seated properly. That means the bead is at the shoulder of the rim's flange.

Many tyres have to be inflated and under pressure to seal the bead. One has to inflate them with more air per second going in through the valve then getting lost along the yet unseated bead.

For many MTB tyre-rim combinations a compressor is necessary.

Since you were able to seat the front tyre with your pump i the following might be enough: Push the reach bead as far on the shoulder as possible then pump very vigorously until you hear the beads pop into their place. This can be very loud. A little sealant might help to increase the initial seal just enough.
