Assuming the OP has found the leak, which probably was caused by a small piece of road wire, there is no reason to replace it. A quality patch system, like Rema TipTop, will give a permanent fix. Why contribute to filling our limited landfills?
Apply a good coat of baby powder to the inside of the tire prior to mounting. This will reduce friction and let the tube move inside the tire more freely.
Do you really think that a pressurized tube can move within a tire?
I consider Jobst Brandt to be the final word on most things related to bikes. He claims that
talc is of no benefit and may actually cause air to be released more quickly from the tire in the case of a puncture.
