    I have a problem with my tyres
    i have to pump them up nearly every week its very annoying
    im sure i have a slow punture in one but i brought that tyre to a punture repaire place and they cheaked it out and said theres no puncture and pumped it up and gave it back,
    They are low profile tyres and i have to pump up the other ones fairly regularly too
    Does anyone know why this would be happening?

    What kind of driving are you doing?

    Are the tires fitted correctly?

    What PSI is it dropping to, from?

    Check the valve on the tyres as air could be escaping. There is a key to tighten them best ask your local tyre fitter about this though.

    I do a lot of aggressive driving because i can never keep tract of time lol

    Ya the tyres should be fitted properly because it was the tyre places that have put them on

    I pumped all the tyres to 40 then a week later cheaked them the front one which im sure has a slow puncture in it went down to 10
    and one of the back ones went down to 25/30

    If I'm not mistaken some valve types are adjustable (maybe this only applies to bikes(the ones you cycle):o), but ask your local tyre fitter for details.

    You mentioned that they're low profile tyres.

    I'd hazard a guess that you may have cracked or buckled the alloy wheel. If its cracked air can/will escape through it. If its buckled then air can escape around the rim of the tyre.

    Do you remember smacking any big potholes?

    Try putting 1/4 can of tyre weld in each tyre?

    I had a similar problem on an old car that had pitted alloys allowing air to escape where the rim met the tyre. A bit of tyre weld in each tyre sorted them right out.

    I done this 4 times now, its the worst. Its always put the tyre to 0 instantly though.

    `you may need to get them re-fit but this thime get them to apply plenty of bead sealer on the tyre before application. I had this problem too with an old car i had . As previously mentioned if the wheels are pitted or warped slightly air will escape.

    bead sealer is put around the rim and then fit the tyre. That and change the valve, then see how it goes.

    Squirt some water with washing up liquid all over them, any leaks should reveal themselves quick enough.

    Happened to me before with a golf. I had seriously low profile tyres on it - Never ever again they broke my heart!

    I tried water to see if any bubbles etc nothing showed up. replaced the valves.

    Anyway what i found in the same situation was to get the guys in a tyre centre to apply a glue like gum (they have a name for it - the tyre equivalent to silicon) to the rims between the tyres and the wheel walls meet. It seals up the minor leaks around the sides. Job done.

    I have to say though it really put me off low profiles forever more. Would'nt touch them now.

    What he said.

    Alternatively, pump the tyre up to pressure, and dip the whole wheel in the bath/swimming pool/fishpond/cattle trough/whatever.
    Any leak will quickly become apparent.

    Any chance they are alloys and you've damaged the inner walls of the wheels driving into potholes and the seal between the tyre and the rim isn't good???

    Not if its as slow as he says. Spray it with detergent or something that bubbles, then play the waiting game. Dont forget to pump it to pressure first
