[Closed] Split sidewall - best way to fix?

Bin it.

Stiff piece of plaggy (pop bottle maybe?) with filed ends so its not catching your tube, glue it in with bathroom silicone sealant.

Variation on this works for my mtb tubeless tyres

😥

For holes that size I just do exactly the same as fixing an inner tube but on the inside of the tyre with a large patch...has worked fine on many of my tyres. If it doesn't work, you've only wasted a bit of glue, a patch and 20mins of your time.

i bin road tyres with a split, but repair mtb tyres.

mtb tyres aren't pumped up with so much pressure. if road bike tyre goes on you then you're f%^ked.

Aye, fair point there alpin...as I don't have a road bike, I've only ever repaired mtb tyres using the patch method.

Ah, nuke - I like that idea. Have some tubeless patches that should do the job. Not sure if I've got the tubeless glue for it though.
The fact that it survived 10 miles of pretty rough roads with the hole, makes me think it'll last being fixed in some way.

use a patch on the inside of the tyre (there are specific tyre patches available) and then sew it up using dental floss (pref. mint flavour).

Personally I'd bin it, but if you go down the repair route stitch it up with dental floss before you patch it up on the inside. Oh and run it on the rear coz then if it does give way at least you'll have a better chance to steer out of trouble

Good tips folks. Thanks. Now to find a needle 🙂

I've used a similar fix with milk bottle ad gaffa tape before on a road bike. Only as a get me home but it easily did about 20 miles

Also could be worth considering...

Think I might get those myself...in stock on Amazon

Bin it. Road crashes are just now worth the risk!

^^ or just carry an old toothpaste tube with the ends cut off. pressure of the innertube against it will hold it in place.

How would it make me crash? Serious question! It can't go any worse than when I hit the drain, surely?

If the tubes comes through the hole again and bursts you'll go from 100+ psi to 0 in a fraction of a second. At the speed a road bike goes that will not be fun. Guessing you'll see speeds 40mph+ fairly often?

Mtb instant punctures can be tough to hold with nice big rims. A skinny flat tyre, skinny rim and fast speed on a roadie are really not going to end well.

Guessing hitting a drain was either fairly slow or not instant (or just lucky!).

Not worth taking the risk on a roadie IMO and I try not to spend money whenever possible!

[i]Guessing you'll see speeds 40mph+ fairly often?[/i]

Er, no! You guess wrong! Commuting only and there ain't no downhills like that round here!
Drain hit was an instant pinch flat, but yeah, wasn't moving too fast.

It's DezB, not Thor Hushovdt. Dezzie rarely sees 40mph even in his car...

carry a cleaned out section of a toothpaste tube in your repair kit. use it to stop the inner tube from bursting through so that you can get home safely. i have ridden mtb tyres with a patch for the sidewall for ages. for road tyres which are under higher pressure i would bin it and get a new tyre.

just bin it. for all the time you could faff around with trying to bodge it, you could pop into a local shop, and buy a £10 - £15 Schwalbe Blizzard type road tyre the same size and carry on as normal. I appreciate its your commuter, but dont be that much of a skin flint on it.

Skinflint?? 25 bleeding quid them tyres cost!

LOLs at Elfin 😀

Throw it away once you get home, but here is the US there is a common emergency repair, using a hopefully small denomination of American money. US currency is printed on a special form of paper made from linen and silk, and it is incredibly strong. I have seen emergency sidewall patches made from a dollar bill, which is big enough to cover a sizable rip.

Not sure what UK money is printed on.

Instead of carrying part of a toothpaste tube I find that a used energy gel wrapper does the trick and more likely to be in a biking bag than the toothpaste tube!
