Hi Dave. I already have a tyre repair kit with a comprehensive list of things in it, spare valves and caps and all the goods. I was curious about the tube because if you puncture the sidewall - usually tyre is done... but I think with a tube it might be saved in an emergency...
Nope if the side wall is damaged you can't fit a tube as the split will pinch the tube, I once repaired a 2" split in a side wall good enough to drive it out of deep creek 1. Once you damage the side wall tyre is history.
