What kind of pump/attachment do I need for this? (picture) I am having trouble identifying what tools I need to pump these tires.

We bought some kind of kit that came with multiple attachments and none of them worked. Wondering if something is missing?

All I've ever used before is a presta valve so I am not too well versed in this stuff. Thanks for your help!
This is a regular Schrader valve like you will find on many car tires.
Your pump (if it is a bike pump) should have something to pump this up.

If in doubt, head to your local service station and try their car pump. 
Alternatively, hit up a bike store, they should be able to get air in that for you!
