Very often the sidewall of your tires can tell you what size to look for; your user manual as well.
But if not, you should be looking for a:
- 16" front tire/tube, size 305mm (<--but make sure it is the 305mm size, and not the 349mm size.)
- 20" rear tire/tube, size 406mm

The 16" and 20" tire/tube will be easy to find (less so the 349mm size), as they are the more common sizes.

Gaerlan does a good job of giving a brief explanation about this:
16" tires (http://www.gaerlan.com/bikeparts/parts/16wheel/wheel16.html)
20" tires (http://www.gaerlan.com/bikeparts/parts/406wheel/wheelbmx.html)

Also, you can look here as well, under the "Tires and Tubes" section:
Hostel Shoppe (http://www.hostelshoppe.com/cgi-bin/search.pl?category=700910)

"20" inch tire comes in two ERTO sizes: 406 and 459. 406 needs an innertube that is
18-19" diameter where 459 innertube will be 20-21" diameter. BMX bikes also use
20" wheels but with 1.75 to 2.1" size tires which need a larger diameter tube. Tubes
should be fit to the tire. 406 tires come in a range from 1" or a bit under to 2.1" and
the tube for a 1" would explode inside a 2.1'' tire where a tube for a 2.1" tire would barely if at all fit inside a 1" tire. Gaerlan and Hostel Shoppe cover some of this but be aware of the BMX factor and that BMX bikes are a LOT more common than bents,
so unless the shop sells bents, a "20in" tube may actually be for a BMX tire.
www.poweroncycling.com also covers this. Steve
