Tyre repair suggestions?

I have a steel fast road bike with narrow wheels (Mavic MA40) and 700x25 tyres which are very nearly slicks. I only use this on fine days and good road surfaces. The tyre has a cut through the outer rubber layer and through to the carcass , which is in good shape itself. The whole tyre is in good shape apart from the cut. The photo I have posted does show it with a clothes peg holding the beads together, thereby exaggerating the slit. When on the wheel with the tube inflated it is barely visible but I could put a fingernail underneath the rubber and lift it.

Whilst I am not concerned about the chances of an explosive decompression of the tube, I think the tyre will make punctures more likely. I would appreciate any suggestions as to what adhesive would be suitable to fix the rubber to the carcass ply.

Never seen a hole like that. Do you know how it hapenned?
No, I have no idea what caused it. As I originally posted, it's only visible like that because the beads 180 degrees opposite are pinched together. When it's on the rim, there is hardly any sign of the slit. When the inside of the tyre is inspected, there is no sign of anything at all, so I know the ply in the carcass is intact and am really only bothered about a small piece of sharp grit getting in the slit and puncturing the tube. A repair by the roadside is not fun when it comes to getting the tyre off and back on the rim, as anyone with MA40s will tell you.

Whether it's normally visible or not, the slit is still there. Even I'd bin it and I'm a Yorkshirewoman.

Thank God you saw that before it failed going down a hill at 30 mph or trying to stop before hitting something. Please replace that before you injure yourself or someone else. Having broke my pelvis about 18 months ago on a bike, I can say that if I could have avoided that accident, the hospital stay, 2 weeks in rehab and months on crutches for 50 bucks it would have been a bargain.

That tyre can be rescued. The procedure I would use is to remove from the rim, and place in a special curing bin, usually a light green one is the right one, but that can vary by area, so do check which is the correct colour. A specialist operative will then collect it and resolve the issue for you at a place called 'landfill'.

Then buy another bleedin' tyre!
