    tire pumping assistance needed

    I own this bike: https://www.giant-bicycles.com/us/co...sl-1-disc-2018

    Factory tires on it, tubeless.

    They are a bit deflated after not having been on the bike in awhile.

    I've never had tubeless tires before, as I am a beginner.

    Can I pump up these tires with a regular old floor pump like I used to do on my old bike with tube tires? If so, do I need a special valve on the pump?

    Or, can I not do this, and if not, what do I need to do to get the tires back inflated fully?

    Thanks in advance.

    Can you pump them up w/ a regular pump?

    Maybe. Depends on a couple of things. Generally floor pumps don't put enough air volume into the tire quickly enough if the bead has come unseated. If the tubeless sealant has dried up inside the tire you'll have to add some. I'd just try inflating them and see what happens. If it doesn't work you know what to do. It's impossible to provide an answer that's 100% over the interwebs.

    Yep, mostly.

    I always have been able to. Sometimes with no issue (no air but bead still set or mostly set), sometimes with using my hands to get the bead as set as possible before using the pump (when the tire has been off the wheel, or when adding sealant). Pump really fast for a few pumps, then normally, that's worked for me.

    An air compressor does the trick. If you don't have one, you can take it to a gas station and give it a quick blast to get it started, then finish with a hand pump. Might require getting an adapter for the presta valve, which are cheap and good to have in any case.
    .

    In the immortal words of Declan McManus:

    Pump it up, until you can feel it
    Pump it up, when you don't really need it
