    Default Correct Puncture Repair

    What is the correct method of repairing a puncture in the dead center of a rear tyre? Plug or patch from inside? As far as I know a plug is a temporary fix until you can get it patched. Is this correct and true?

    Personally, I'd do as exactly per your question, plug temporarily and take it easy. Do proper patch ASAP. A rear tyre is crucial and not something I'd take shortcuts on

    Perfect. Thanks. I would imagine that a "Mushroom plug" is a plug as the name suggests? I specifically asked the dealership to patch and not plug and now I see that they used a mushroom plug. How hard can it be to give the customer what they want

    Linux Yamaha repaired a puncture on a tubeless rear tyre with a mushroom plug a few years ago - stripped the tyre off and inserted the plug - the workshop guy said that he is happy to do it that way because it is a high-speed rated tyre and a heavy bike (R1200R) - he could probably (correctly) surmise that I tend to go quick

    Ran the bike with that plug repair without any hassles until it was time for tyre replacement.

    Have also done my own road-side repairs with a Stop-n-Go mushroom plug kit - again, ran the tyre thereafter up to replacement. Cytech recommends the Stop-n-Go kit for their cross-country rides and I must admit that I think that there is no problem with a decent mushroom plug repair instead of the patch that you wanted.

    A mushroom plug is basically a patch (the head of the mushroom) with a plug (the stalk of the mushroom) that goes into the hole. It is the generally accepted way of repairing a puncture. http://www.bridgestone.co.in/PlugMethod.aspx (For a car tyre, but exactly the same principle)

    Thanks for the info. I'll keep an eye on it and also monitor pressure in the tyre.

    A mushroom plug is inserted from inside the tyre and almost impossible to see, after the repair was done. If you can easily see the repair from the outside, they probably did not use a mushroom plug, but rather those string plugs.

    This is what it looks like from the outside. I noticed a little glue or liquid oozing out yesterday

    That is a mushroom plug and should be fine. No issues as it is actually a patch on the inside of the tyre.

    My 2c...

    Depending on the bike, speed, load etc. - personally I tend to replace the tyre for safety reasons and peace of mind. Probably depends on how and what you ride and if you tend to carry a pillion at speed. Many opinions on this topic though. Heres a good guideline for reference: https://www.motorcyclenews.com/new-r...ture-repairs-/

    You will see they give some guidelines on the rating, position and size of hole etc.

    Yup, mushroom plugs are basically patches from the inside and are perfectly fine, I've actually got 2 in my Pirelli Supercorsa's at the moment...

    Personal preference to change out tyres with the mushroom plugs, but they won't lose integrity easily - IF done properly.

    Just check your tyre pressures more regularly before hopping on for a ride though.

    +1.

    For any use less than severe racing conditions on a slick tyre, a mushroom plug is fine.

    To be honest in my view racing conditions is probably far less strenuous on tyres than the road. Accelerating a 200hp bike like a hooligan over bumps and drains requires allot more from a Tyre than a smooth track surface with constant grip.

    I would recommend that each do their own research about this topic and make their own decision. Look at https://www.rideapart.com/articles/2...orcycle-tires/ or https://www.motorcyclistonline.com/t...torcycle-tires There are many more articles about this topic. You will see in the articles they mention that V rates tyres forfeit their speed rating and its recommended to not exceed 80/85mph when repaired and it seems even some insurance companies have clauses around this. There are so many variables to consider that there is probably not one expert that will say when you plug a tyre its all good. There's always a warning or a "but or if" involved.

    But like I said so many views and variables around this and because if the way I ride, carry pillions, heavy bike, lots of power, etc. I lean towards the safe side..

    As always, views will differ and yes, each should make the decision for themselves.

    A patch in the middle of the threaded part of the tyre is considered fine.
    A patch in the sidewall is not.
    A race tyre is much, MUCH softer than a road tyre.

    Just an update on the mushroom plug that was used to plug the puncture. My bike was returned to the dealership today as the rear tyre was not holding its pressure at all. After 2-3 days the tyre was losing about 1 bar of pressure. While washing the bike this weekend I actually heard the air leaking out from the plug. Hope the dealership can fix it properly this time round. Im a bit concerned that they might suggest a new tyre as the solution to the problem
