I'm ordering some spare tubes to start doing tire/tube changes at home, rather than taking the wheels to the bike shop.
The front tubes seem fairly self explanatory, but what size rear tubes do you guys use? I'm running a 100/90-19 rear on my 144 and a 110/85-19 rear on the 250, so I'm assuming that I should be using the same sized tubes for both.
The tube measurement system is confusing to me. I want to go with the smallest/lightest available for this wheel/tire size, so what would be my best bet?

They list a 100-110/90-19, which sounds like it should be perfect for either.
But then they also list a 3.60/4.10-19, which is $5.50 cheaper.
I'm assuming that the 3.60/4.10-19 is slightly smaller, and should be perfect for the 100/90-19 tire. But by my calculation the 110/85-19 tire should need a tube measuring 3.75/4.40-19. Am I doing this right, or am I overthinking it and the 3.60/4.10-19 tube will work fine for both?
