This is the bike in question:

https://www.walmart.com/ip/Schwinn-A...-Bike/15711186

The tire size is 28" x 1 5/8" x 1 3/8" (37 - 622) 400 x 35c
The flat tube says 700 x 35/43c

Available to me at Walmart a

Bell Inner Tube Standard
27" Asos fits 700c 28 x 32c
Fits tire width 1 1/8 - 1 1/4

------or

Bell inner Tube Presta
700c ROAD ONLY
Fits tire width 25 - 32c


Either would work but if you can find a wider (700 35~45)
tube it would be better as it will not stretch as thinly to
fill your wider tire. At any rate be sure to find the cause
and correct the problem before fitting a new tube.
