Aloha guys..

I need some help with my tires. I just bought some 4" dubro tires to up graded my 3 1/2" foam tires. Now here's my problem. The tires come with a valve on the side of the tire, I have a device that screws into the valve, what kind of inflator do I use? is it the small hand pump like to ones used to pump up balls. There was no instruction on the tire card or any explination on how to put more air into the tires.
Thank you very much for any and all the help you can give me on this situation.

Mahalo from Kauai,HI.
