That's not a slow leak. Slow is 0.5psi/day.

Check your rim, and the inside the tire for sharp protrusions.

I bought a new tube and installed it, pumped up both tyres again. Next morning the rear tyre is flat... Again after a pump it would last the day before needing to be pumped up again.

Same issue with both after topping them up. Why? I don't get what caused it. The tubes are Presta Valve Schwalbe Extra Light (406). What could I be doing to them while pumping to cause the slow (maybe 2-4psi per hour) leak?
