Stop'n'go tyre plugger

Been using them for years in cars, van and bikes without a problem.Both mushroom and sticky stringy types. The worst that can happen is a slow puncture but it's never happened to me.

What's the worst that could happen? I don't really know but if the plug falls out surely just another puncture and being a tubeless not a blow out but a steady deflation. Sure it will be faster than the original puncture but not a blow out. Right wrong???? I dunno but the twice I have used stop n go they lasted the remainder of the tyre.

live and learn - before longer trips check if the rubber plugs are still rubbery! Have been dragging around Europe a puncture repair kit for last five years until I needed it for a first time last summer. All the rubber plugs hardened and did not work anymore! :pinch:

luckily got the puncture in a city, so managed to sort it out quicklyish.

You ream the puncture into a clean hole about 2mm in diameter, before fitting the plug that'll be 4mm by the time the plugs been in there a while.

If the plug did come out, and I'm not saying it will, plenty people seem to treat them as a permanent repair, deflation would take seconds.

That isn't good if your on a motorway, about to tip into the next corner, or about to get heavy on the gas, for instance an overtake (rear tyre) or about to haul on the brakes, for instance motorway slip or roundabout on a dual carriageway (front tyre).

When I have plugged tubeless the reaming didn't create an open hole. In my experience (twice only admittedly) it cleans it in preparation for the glue on the plug and opens it up enough to get the insertion tool in, but inspecting it before installing the plug and the tread and carcass pretty much closes it right up. Not air tight for sure but not a gaping 2mm hole. I agree a sudden deflation in any number of scenarios would be unpleasant, but it doesnt have to be a plug letting go for this to happen.

Mine did, but then the hole was reamed twice as the first plug didn't hold, it was basically the same size as the reaming tool, the point is to create a nice even round hole for the plug to fill. Once in the tyre it was easily big enough to find the plug just by rotating the tyre and looking for it, like I say probably a 3-4mm hole.

A mate used a plastic screw from his number plate to plug a hole. It was still there with no leaks when he finally replaced the worn out tyre (thumbs)

I did end up with a slow puncture on the car after about a year from a repair site where I used a sticky string.

It's not a permanent repair and will prevent the tyre from having a permanent repair being done as it'll stretch the hole too far. Chances are you'll be fine and it'll last the life of the tyre. I've personally not seen one with any issues more serious than a slow leak in which case you've got a few extra miles over replacing immediately.
The permanent ones are done from the inside, have a patch about an inch or so across that is glued to the inside of the tyre after the surface is smoothed and a bung pushed through. Any average or better bike shop that does tyres should be able to do this, car places are tending to shy away from bike tyres these days.

cheers fellas, no horror stories so as it was a clean small pozidrive screwhole and the mushroom has taken well (no air loss in 3 days, after a few rides) and the tyre is 3/4 worn anyway, and will only be used on road, it'll be lived with.
