I replaced it with another new tube, fingers are crossed.
Is that finger-cross thing 3x or 4x?
I've seen defective tubes.
You said 90deg from the valve. Does that mean around the wheel or on the side of the tube? The latter may indicate a pinch hole from when you squeezed the tire on the rim. Tire irons can be deadly to tubes.
