Help with tires sizes/ tube sizes

[benjamin550]

Hey,

I'm buying some new tubes and tires, and I have been searching around online for a few conversion charts to help me understand which tires/ tubes I can by. My bike is 2.75-21 Front and 4.10-18 rear. Can anyone explain to me what other tube sizes I can buy since its not always possible to find the sizes expressed in those numbers.

Thanks!
