How to repair tyre cuts?

[StreetCowboy]

Young J has joined us on our weekly explorations, and he rides a proper road bike with road bike tyres.  Despite his youth, he’s good natured and stoic - he must have some mettle to come back after his first ride - knocked off his bike and poisoned, but still cheerful!

 

Unfortunately, many of our rides involve a bit of - not off-road, but maybe ‘other road’ - sometimes, nearly-new roads… we’ve been on DASH highway prior to opening, prior to surfacing, prior to final concrete pour and at the hardcore formation stage. And sometimes roads that fall below ‘alternative recommendation’ on Google Maps. Summnday was one of those.  It was definitely road gravel, and not river gravel, but it was still pedal-deep in places.”

And this morning he mentioned the cuts that his tyres had suffered.  Not through to the tube, no punctures, but I worry that the slits will pick up muck that will work it’s way into the tyre and make the cut deeper until it results in disaster.

So what do you recommend, to keep the tyre in faithful and reliable service?  Maybe fill the crack with a rubbery adhesive? Anything hard would probably fall out as the tyre flexed…

You add an inside patch for emergency use, and buy/order new tires

The cuts don’t go all the way through, (not yet) and there’s still a few thousand km life left in the tyre otherwise.

If the cuts have severed any of the reinforcing ply structure there is no life left, it is new tyre time. It also looks as if the wear bars are giving the same information.

Still it will reinforce the tire from inside, but to me it looks like new tire, and saved frustration maybe. 
 

Anyway let us know what you come up with as a fix. A gas torch and some rubber? Preheat the damaged part of tire to melting point add excess  rubber stick and melt  to the cut?

One can repair some  cuts ,they can be vulcanized  at some tire repair shop. 

That can take some time if they can do the repair.

If there area few cuts in the tire and side wall it will be cheaper to bye a new one.
