This tyre a bin job?

freehub

Got a cut in it, I think it's torn the top threads, but it's not massive, is it safe to keep running these tyres as long as I keep an eye on em? Seems a shame to bin because it's stick thick on the thread atm so plenty of life left.

first look at the foto suggests that its not over just yet. This kind of cut is more of a problem when dirt and the like gets in and starts wearing further.

You can protect it by filling it with super glue or "shoe goo" (stuff used to fix soles on sneaker etc.)

I put a inner tube patch in the inside of the tyre to give a bit more protection. I then pump up tyre to what ever and superglue it. It might take 6 or more very thin layers, leaving each layer about 10 minutes to dry. I might cut a small bit of old rubber and fill the slash then superglue it.

Shoe goo might be a better option but dearer (I get loads of superglue in Poundland). It will be more flexible.

Most of my patches last a few hundred miles before needing a top up.

BTW, I live near Broken Glass Alley

So you superglue with the tyre pumped up fully?

Garz

Last time I done this to get more mileage out of my tyre I deflated to superglue, let it set overnight, then inflated.

I found if you inflate too soon the high air pressure can cause the cut to open dependant on where the slash is on the tyre.

Buckled_Rims

I think some glue it fully inflated like me and as Garz mentions, others deflate it and glue it.

I've always done it inflated and had no problems. But I put many thin layers on filling the hole while others glue the cut once.

Time to experiment!

what about some contact adhesive, like Evostick

used to repair many shoe soles with this in the past

epic stuff - rebonded carbon cycling shoe soles and vibram ice climbing boot soles, etc.. rubberised so slightly flexable.

i'd probably pit a drop in deflated and let it cure for 12 hrs before inflating

onceopen, keep in freezer and defrost for use - stops it goung off in the tube.

ive had a cut in one of my Conti 4000S tyres about the same size as that for some time and have done about another 2000 miles on it since and it hasnt got any worse, so i.d keep using it, others might not risk it and change it.

That's a good piece of advice Gerry, never thought about the freezer. Thanks.

I'll give some super glue a go before trying anything fancy.

Keep a close eye on any superglue tyre repairs you do!

I spotted a cut in my front tyre the evening before flying to Spain. I superglued it and packed the bike away in its box. Then I forgot about it...

I rode the first few days of my holiday without any problems. We did a good day's riding in the mountains, including a fabulous 50+ mph descent off the last one of the day. There were some high-speed bends with very little protection to stop you falling a long way if you went off the road.

Next day before we set off from the hotel, somebody tapped me on the shoulder and pointed at my front wheel. The repair had ripped open and the tube was bulging out and ready to explode! :shock:
