The front tyre on my bike looses air pressure despite there being no punctures. There is no leak via the Schrader valve either. If I fill up the tyre, it looses a considerable amount of pressure by day 3. What could be causing this?

4if a tyre is losing air, you either have a puncture or a faulty valve. There is no "third way". – PeteH Jan 3 '16 at 15:20

What about the age of the inner tube? Or the quality. Some are porous from the factory. BTW: How did you check for punctures? If there's a slow leak you will probably not notice it when holding the tube in a water basin. – Carel Jan 3 '16 at 15:21

@PeteH Negative on both. I checked for punctures and faulty valves, and also took it to a local shop where I got it confirmed. – amal antony Jan 3 '16 at 15:21

@Carel How do I check for slow leaks? – amal antony Jan 3 '16 at 15:23

You can keep adding air and provides more pressure by squeezing the tube. It should be immersed in water bath – Nhân Lê Jan 3 '16 at 15:34
- A puncture
- The tire lining along the valve is faulty.
- The seam in the tire is faulty somewhere around the tire.
The best way to find out is put some soap in a bucket/tray of water and cover the tire. Fill it up as much as you can and the bubbles are where the leak is!
