Repairing road tubeless tyres

My schwalbe one tyre punctured last week. Although the orange sealant sealed it at about 30 psi it would blow out when I put more air in.

When I got home I sanded the inside down and stuck a patch in it. Blew it back up and it held air. The hole was actually very small and I even struggled to find it.

Half way round my ride it blew again. When I checked it the patch had a small hole in it. Obviously the patch idea works but at high psi it doesn’t.

What are you using to repair road tubeless tyres? Are there any stronger patches I could use?

I’ve currently got a tube in it and I don’t want to give up on tubeless.

The jury is still out on road tubeless for me. When it works its great.

Has anyone had any better results using glitter in the sealant?

Thanks

When I checked it the patch had a small hole in it

That’s either outrageously bad luck / coincidental or there’s something in the tyre still
(or you’re using 10,000 psi to force a glued-on patch through the carcass until it pops 😀 )

I’d re-patch it after supergluing the orignal hole (dig out any glass/flint first) – should be fine (could press on the patch by putting in an innertube overnight but if you’ve cleaned & applied it right should be no need)

+1 for wot scaredypants said…

I’ve used tube patches to fix road tubeless tyres without problems – some decent size holes too (4mm ish). I use the more chunky patches that are 1-2mm thick.

I couldnt see anything in the hole when I checked. I’ll double check.

It’s not even a big hole.

25mm and I’ve always run 90 to 100 psi

did you use a normal innertube patch or a tubeless patch?

A normal patch. I’m now off to Google tubeless patch

OK, I didn’t even know such things existed,

Any recommendations?

These look good

I use the Weldtite one, but it’s probably the same. They are tougher than a tube patch, and glue is more like ‘cement’.

FWIW I’ve only ever used normal patches

(and your “failure” was re-holed, not adhesive failure or anything that a “special tubeless” one might address)

The tubeless glue is superglue (cyanoacrylate). On which note, I found I could glue MTB tyres back together with superglue if sealant didn’t fix the holes, no idea if that would work on a road tyre but might be worth a try.

I’ve always struggled to fix tubeless road. The inside of road tyres are textured and the super glue stuff is too runny/watery. I suppose it depends on decent preparation, but I’ve never been able to get the patch to hold, even having sanded the inside of the tyre at the puncture site – unless I wanted to also glue my fingers to the arrangement too 😳

the weldtite tubeless glue isn’t like superglue. Well, it doesn’t look anything like it at any rate. It’s more like araldite consistency, and blue.
