Repairing a 1cm slit in a tyre ?

[bonj2]

Put a piece of old tyre inside the slit tyre, covering the slit, and use it only on the back wheel. Keep an eye on it to ensure that the slit isn't bulging much (opened out more than a mm or so), checking whenever you pump the tyre up.
I've got full life out of a slit tyre that way, and I've known a fair number of other people who've done likewise.

I DON'T agree with that method. The extra piece of tyre is going to cause a bulge in itself and make your wheel rotate unevenly!

It doesn't.

It doesn't.

tyres are the only point of contact between your bike and the road - not a good idea to have some make-do-and-mend patchwork bodge.
Besides, one side of the tyre doesn't wear faster than the other. It's split because the tyres worn - if it's split in one place, it's not long till it splits in others.

It's quite a well considered bodge, especially when you can't afford a new tyre, which is rare these days I'll admit. As Jimbo says, PR kits used to have a bit of cloth in for that purpose.

Anyway if the split is a cut why would it spread or break out elsewhere?

I'll tell you what. You send me two of your tyres, one new, one old, new one with a split in and I'll send it back fixed and you can try it out.

You'll be telling me next that when your inner tube splits at the valve you don't fix that either.

How about that self sealing insulating tape ? (wish I could remember what it is really called).

Self-amalgamating tape? Damn useful stuff.

It was sliced open by a nasty piece of road debris - the tyres went on back at the end of April / start of May, so aren't old.

By way of demonstrating that I practice what I preach, here's the current state of my back tyre, complete with 8mm cut that goes right through. A couple of suitable bits of old tyre live in with my spare tubes.

Very neat repair ! I may slice up one of the old Kendas that came with the bike and put some 'emergency sidewall patches' in my saddlebag for future get-me-home-with-a-slashed-sidewall emergencies.

Ok, I'll bit. So how do you fix those?

You don't.

Well it's not a permanent fix, just a get you home one.

Ordinary patches won't do it, you need to be carrying a large rubber patch sheet which you cut your own to size from or just a very large patch, say3x3 cm. If you are, make a narrow cross cut in the middle of the patch and force it over the valve, letting the valve make the cut bigger. Use the glue as per normal and a judiscios amount of pressure, sprinkle with prayer, re-insert and pump up - It'll get you home.

Best to do all that before the inner tube splits at the valve. I bodge all my tubes in this way, they all get a patch (I've experimented with pieces of inner tube glued on, but not as good) in the way you describe to reinforce this area.

Do you. I think I've only had 3 or 4 tubes split this way, though one was in the middle of nowhere on a track.

Yeah, I do it mostly on my MTB and when I remember on my road bike, too. It happens more on MTBs because all that hard braking sometimes makes the tyre rotate on rim, dragging the tube with it which puts tension on the valve seat. Another tip is to put plenty of talc in your tyre so if the tyre does rotate there is a chance it won't take the tube with it (effectively lubricates the rubbing surfaces). As I said, a phenomena more closely associated with MTBs, really.

In the past I have cut the entire tread from an old tyre and stuck it on the inside of another one. Virtually puncture proof but quite heavy.
However, this was in the time when I was early 20's and did everything to put weight on my winter bike - as a training aid!

Made them a bugger to put on and take off!
