My father in law bought a bike for his grandson and one of the tubes are bad and he is trying to find a replacement before Christmas. The bike is a 24" Mongoose Logan with 4" tires. I can't seem to find any and I was hoping someone around here could help. Thanks in advance.

And sorry if this question is in the wrong place.

Did you try walmart?
Bell Sports 24" Self-Sealing Bike Inner Tube - Walmart.com

I tried Walmart, but they do not have tubes for the 4" tires.

This may not be applicable but have you asked a tire shop if they can repair it?

you local bike shop may be able to get these, which might be close enough: https://www.jbi.bike/web/checking_pro...t_number=63238 24x3 tubes seem to be pretty common, so you might have to make due with those.

irony! you are discovering why these bikes are sold so cheap at walmart- they are disposable junk. once you get a flat, the bike is just about useless. put a kid who is going to ride through grass and into curbs on those cheap tires, and you have a constantly un-rideable bike.

thanks for the valuable information
