Do I need new tubes ?

Hi folks,

I have question that you may know the answer for. I am replacing the
off-road tires (24x1.95) on kids' bike with slick tires (24x1.25) for
road.
My questions is: Do I need to buy new inner tubes to go with the new
1.25 width tires, or will the 1.95-tire tubes work with the 1.25 tires?

Tube fit is not highly critical. There are tubes that would work with
both sizes, but if your tubes are actually matched to the 1.95 fatties,
they'll be a poor fit in the 1.25s. This could make it hard to mount
the tires, and the tubes might wrinkle inside the tires, leading to
leakage down the line.
