cheap tubes plus Houston Sunshine equals flat tires.
and months is not "suddenly".
the tubes show signs of literally MOLDING themselves to the tire... note the serrations... that's from the tires.
Bike Tires lose air over time...
Hot sun does REALLY bad things to Cheap bike tires and Tubes.
Where the stem is bonded to the tube is even coming apart.
