Deflating wheel?

[DangerMice]

Get thee to the tyre shop sharpish.

I had the same thing. Jumped on after a weeks holiday and felt the rear much lower than it should be. Jumped off and found it was 10 psi down (little scooter tyre normally that runs 36 psi). Thought it was bloody odd but it seemed to hold pressure so made a mental note to visit shop at next opportunity.

3 days later it started to feel a bit loose again halfway to work, called in to a garage to check it, 4 psi down this time, so I decided to head to scootling which was a couple of kms away. 1 km later the valve blew out with enough force that the top of the valve cap blew off leaving just the threaded part behind and the needle was half hanging out. Near instant deflation, a moment I wouldn't like to repeat.

Pump it up and straight away get a squirty bottle with some washing up liquid and water mixed, spray it around the valve - you should be able to see if its leaking at the valve or not by bubbles forming. I assume you spun the tyre and checked closely for any pins or nails stuck in the tyre itself. Blowout on a car is bad news but most people limp safely to the side of the road, a blowout out a bike is never going to end well.

Please tell me NO ONE is this stupid .

God, I hate idiots sometimes

I didn't really suspect a puncture because at the moment the tire seems to stick around a constant pressure. A hint if it was flat would be that the tire would have deflated fully.

And I do ride with it fully inflated, I just don't want to constantly take trips to the Gas station to fill it up every 3 days. Waste of petrol really.

Just because the tyre is not fully deflating does not mean it does not have a puncture. A really common puncture for a motorbike is a nail stuck in the tyre. The tyre only slowly looses pressure - unless you remove the nail (hint, don't remove foreign objects until you get to the tyre store if the bike is still rideable).

Try spinning the tyre around while the bike is on a stand and see if you can see any foreign matter stuck in the tyre.
