Filling (or fixing) a gash in the tyre? (now with photos)

After a puncture, I now have a gash in my rear tyre that's about half an inch across and about 4mm wide (when the tyre is pumped up).
I's there anything I can fill it with or anything else I can do to make it less vulnerable? It seems a shame to throw the whole tyre away as the rest of it is fine and it's only a couple of months old.
I seem to remember some people on these forums talking about filling it with glue. Is that a good idea or not?
Edit: copying photos into this opening post so that people who are looking at the thread for the first time can get straight to seeing them.

Hello !
Here's what will fix your tire: 60 bucks and a trip to your LBS. Don't risk safety on a dead tire. Better to patch a tube than a tire because you just never know.Your confidence just won't be the same on a buggered tire.0 -
Sounds like a big hole - if it were me, I would bin the tyre.0
-
One thing I should have made clear is that this is not really a hole due to the fact that the measurements I gave only apply to the external surface of the tyre, the inside surface only has a very small hole the size of a pinprick.
But having that large slice on the outside means that particular section of the tyre is at higher risk from repeat punctures in future and I wondered if there's anything I can do to rectify that.0 -
If it's a surface rip, then you may be Ok, but bear in mind the puncture resistance will be compromised. If it's deeper, then bin it.
Personally, I'd bin it anyway.
It's just a hill. Get over it.0 -
Bin the tyre.
I've tried patching the inside of a tyre and the tear propogates anyway because the patch (be that from a patch kit or part of a tube) stretches whereas the tyre sidewall should not.
A patch is the way to get you home though..... indeed by coincidence, I too was swearing at the side of the road this morning as I discovered a torn sidewall and I've had to double patch the tyre.0 -
I'm gonna post a photo of the cut at some point in the next hour or so, as I think I may have made it sound worse than it actually is.
After the photo, if you all still think I should bin it then I guess I'll do that.0 -
Ok, here are two photos, one showing the scale (with a five pence piece for reference) and the second is an enlargement of the cut for closer inspection. Have a look and let me know if you still think I should bin it or whether there's anything else I can do. 0

What tyre is it? (not that it makes any difference, i'm just interested)
The sensible advice is to bin it and i am not going against that but what i have done in the past in a similar situation is fit a tyre liner to protect the tube, run the pressure lower and carry on using it.0 -
bin it.point your handlebars towards the heavens and sweat like you're in hell0

It's a Scwalbe Marathon Plus.
In fact, your thread about those particular tyres is why I'm even on this forum. I went through a patch (no pun intended) of getting lots of punctures on my commute and so I Googled for "best tyres puncture protection" (or something similar, I can't remember exactly) and found your thread on here, so I bought some, joined the forum and the rest is history.
Anyway, my concerns about wasting money have gone out the window now since discovering a crack in the rim of the same wheel with the dodgy tyre pictured above. I've got to replace the whole wheel now anyway so changing the tyre doesn't seem so bad anymore.

Ewww - the photo helps

Interesting. The SMP i have on the rear of my racer has one slash that looks almost identical to that (same angle, same part of the tyre) and one larger. It is the tyre i used the solution above on so it does work at 90psi on a 700x25 tyre, although i wouldn't recommend it.
What size is your tyre?
What pressure were you running it at?
Do you know what caused the slash? I dug the piece of glass out that caused mine.0 -
If you really wanted to you could put a standard tube patch on the inside of the tyre, or even glue a bit of old inner tube over the gap.
In either case I'd personally treat it as a temporary fix until you can get to the LBS and buy a new one.

It's a 700 x 38c tyre.
I run it at 85 PSI (the maximum according to the sidewall).
There was nothing in the slash when I discovered the puncture so it must have already fallen out.0
