Could you guys help me as every time I inflate my basketballs they aren’t as bouncy as they should be and feel a bit off I have a Spaulding leather indoor and outdoor+ a jordan legacy 8p 2.0 black both of which don’t bounce well when I inflate them even though they did in the stores (I did deflate them for a few days as I was abroad and needed to fit them in a bag if that is relevant) What I think might be caused this is the fact that I inflate them with the thing I use to in flat my car tires(you know that small box) and I think it might have a wrong level of psi or something because that is the only explanation I can think of.
How can I fix the bounce do I have to change how I inflate it or do I have to do something else?
