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

What do you all think of this as a solution. There has been some concern voiced that the flat tube in the tire now is not exactly the right fit but this solves my Schrader problem and this seems like it matches up better then the one at Walmart.

Co-op Cycles Schrader Tube - 700 x 23 - 25 / 28 - 32 / 35 - 43
