    How far can you drive on tyre sealant?

    How far can you drive on tyre sealant? 9th Jun 17 at 1:32 PM
    I got a puncture a couple nights ago and the AA came and sealed it. The guy said that because the puncture wasn't a round nail but a thin key, he couldn't seal it properly and it is leaking air. He said it was good for the evening but the next morning may well be flat. he said usually they say a sealed tyre can be driven for 100 miles but with mine it is less and needs to be changed ASAP. however its now 2 days later and the tyre is still hard.


    I had national tyres come out to fit a new tyre today but lo and behold... my brand new car didn't come with a !!!!ing locking wheel nut key. So they can't get the wheel off to replace the tyre. My lease company told me they can book me in to a garage to make a new locking wheel nut key but this is next week..


    anyway I was meant to drive a 140 mile round trip this weekend. and I have no idea what to do.. Obviously I shouldn't go. if it goes flat I am stuffed. But part of me says well worst comes worse, the tyre goes flat again and I get towed all the way home.


    what do you think ?

    Take a can of tyre sealant with you and a footpump. If you get a puncture on any wheel it sounds like you are in trouble for now.

    Sod the foot pump. Get an electric tyre pump and take it with you.

    Check the tyre every 20 miles or so and if pressure is dropping re-inflate it immediately.

    There used to only be about 15 or so "keys", so if they can get in touch with their supplier, you may be able to match/borrow one from another car that works.

    Edit: If there's a main dealer nearby for your brand, I'd take it in there and see if they can get you a replacement key or just swap them for keyless bolts.

    yeah I have an electric tyre pump, the car came with that.


    I got the pressure gauge out and it's at 55 psi ! so safe to say in these 2 days it is not losing pressure. but I've only done 30 miles or so driving very gently. Going to do some motorwaying tonight.


    You're right, I'll check it frequently and pump it up if needed. cheers for the advice.

    Be aware the AA may well refuse to come out free of charge to tow you if that tyre goes flat, as it'll fall under their 'pre-existing fault' conditions. They will obviously have a record of their previous attendance...

    Look in the boot of your car, there should be a electric tyre pump and a can of sealant.

    I suspect -if it goes down- you will only need the tyre pump. However, before you set off check the tyre pressure at a supermarket forecourt, should be about 32psi or 2.2bar, If it goes down it is likely a slow leak that can be topped up with tyre pressure.

    You should check the tyre pressure ASAP, because it might not look flat but it might already have gone down to 24psi.

    I would check it a few times on your journey every 50 miles or so, if it goes down you "should" be able to feel it through the steering.

    BTW I also use these things with great results. But they are not for a novice, they need to be fitted by someone with good DIY skills.

    https://www.ebay.co.uk/i/322017758607

    They are not recommended as permanent repairs, but my idea of "non permament" is "it is OK for as long as it doesn't go down". I have never had them go down, they last until the tyre tread wear forces a new tyre to be purchased.

    Get a puncture and a temporary fix, and they won't cover you for another failure in that tyre with temporary fix (either a leak or another puncture). Get the tyre repaired properly and you're covered.

    So you can't just get them to keep bodging you on; they get you moving again and then expect you to get the car fixed.

    normally the number of the locking key is written down in the service book or other user manuals you received with the car

    can you not go to a main dealer of the car make you have and ask them to undo it and see if they could possibly give you a non locking wheel nut for use short term

    Or replace all locking wheelnuts with non lockers permanently as they are such a pain to deal with and are more trouble than they are worth.

    It's in the T&Cs.


    If you get a puncture, call the AA to bodge it, drive on the tyre for 100s of miles and the bodge fails, the AA won't come and tow you 100s of miles home for free, as you failed to fix a known issue and took the risk of driving in that knowledge.


    I didn't say if the OP got a *different* puncture they'd not be able to call the AA. I mentioned pre-existing faults because the OP said:


    But part of me says well worst comes worse, the tyre goes flat again and I get towed all the way home

    Note use of "the tyre" - as in the subject of the post and "again" - as in 'a repeat failure'.

    That is pretty high for a private car or SUV

    Even my M-Benz Sprinter doesn't have pressures as high as that.

    What vehicle are we taking about here.

    That high a pressure may well induce a failure at motorway speeds.

    Also did you check with a dealership where the locking wheel-nut key is normally located?

    It may not be where you expected it to be.

    55psi is high, but not so high you can expect a failure. I sometimes drive with 50psi, no ill effects, it reduces rolling resistance.

    There are some "eco" models which have 50psi as standard.

    I suspect the AA guy over flated it as a precaution against the slow leak... a slow leak, I might add, which is sounding to me as though it has now sealed ok.

    What you want to do is put some washing up liquid over where the hole is and see if there are any bubbles. However as it is a foam seal, maybe washing up liquid would be the wrong thing to use (might eat away the foam), so just spit on the tyre instead (i.e. spittle from your mouth).
