I recently inflated a tire to 50 PSI. The tire/innertube is recommended to inflated to 30 to 80 PSI (standard tires on RadWagon 3). At 50 PSI however, the innertube started bulging to the point that the tire bulged. After deflating it to 30 PSI, the bulge disappeared and the tire now looks normal again. In the past I noticed the same innertube / tire gradually losing air over time.
I'm now somewhat worried that the innertube is damaged and there is a chance of catastrophic failure. Should I go ahead and replace the innertube or is it safe to ride as long as there is no bulge visible at current inflation levels?
