Is an inner tube worth patching? I noticed after removing my tire the inner tube had a small crack in it, should I attempt to reuse it with my new tire or toss it, if not what size valve stem should I use for my rim Honda Thanks

 

I'd try patching it. Thats what we did in the old days, boots too. Folks that lived thru WW2 had all kinds of ways to keep going when you couldn't get tires, or rubber, etc.
