    Deflating wheel?

    So, since maybe a month ago, I've noticed the front wheel of my bike is always deflating to the point where the steering is becoming sluggish. The thing is, I keep on pumping it up. But the air in it seems to last maybe a few days before it deflates again. Its still rideable, but the amount that i can turn the wheel without the tire moving is still alot.

    Is this a problem I should really be worrying about? Or should I wait just under 4 months until I can get my full?

    And, If it is a problem, What should I be looking at first?

    Get that tire looked at quick, before it kills you.

    Sounds like you have what's known as an air leak! Or in laymans terms, you got a hole in your tyre au.

    Could also be the valve. Or the bead.

    I'm assuming you have tubeless tyres btw.

    +1. Sounds like you have a puncture. Get it fixed before you either/or:
    • Right the tire off due to underinflation
    • Have an accident due to underinflation

    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.

    What type of valve caps do you have?? as some have little o-rings in them to stop air leaks from the valve but if they arent sitting flat in the cap they will press down on the valve causing a slow leak........

    you haven't stated if your tube or tubeless...what bike do you have ???? there is many reasons why airleaks happen even something as silly as a catcus thorn(from when you landed in area 51) will create a leak but seal itself once its worked its way through the tyre

    best you get it looked at asap

    At the risk of shattering your illusions: Some small punctures will self seal (or reduce air loss to a minuscule amount) after a seizable pressure drop, because the tyre structure puts enough pressure on the hole to seal it. But if you have another theory as to how the air pressure is getting lower, without any leaks, I shall await it with baited breath.

    If I had any idea on what the hell I was doing, I guess I wouldn't have posted here. In fact posting here already makes me seem like a mechanical noob. Which I will admit, I am.

    I'll see if I can find any leaks in the wheel itself in the weekend, then see if its the valves.

    And to those who asked, I ride a red GN250. On which someone recently stole the battery cover. Or it broke off.

    If you keep riding it flat orlow then it can damage the tyre. I would just get it fixed.

    Puncture: When the air on the inside gets to the outside quicker than you can stop.

    As you are a mechanical noob, how are you going to know you are checking for a leak properly and if you do find a leak what are you going to do about it? Just take it straight to a tyre place and get them to sort it. Cheapest, it's just the valve, if it's a on the face it will probably be a simple patch fix, if its on the side wall a new tyre, Most expensive, a crack in the wheel. On the scale of cheapest to expensive it is also the most likely it is going to cause the tyre to deflate quickest when you really don't want it to. So even if it is expensive and you can't afford it, you really can't afford to ride it. The chance of it damaging you is huge.
