When that happens, the tire is much more susceptible to tearing and puncture. If the casing does tear, flat protection is reduced and the tube can stretch beyond its usual dimensions. Both of these cases can lead to flats.

Why does my bike tire keep losing air?
Regularly pump up your tires. … For starters, you should know that a normal, brand-new tire and tube will loose air over time.

Can a bike tire go flat without a hole?
To answer the question directly, yes, if your tube is losing air that quickly, it needs repair. It is not a matter of simply being too old. There is likely a very small hole or a leak in the valve. Replace the tube, or patch it.
Why do car Tyres go flat when not in use?
You may find that your tyres lose pressure, or start to slightly deflate, over time while the car is immobile. This is because rubber is porous, and while it’s not enough to cause an issue normally, air molecules can make their way through the rubber slowly over a period of time.

What happens if I over inflate my bike tires?
