Biggest bit of glass I have seem so far....s**t (5mm deep); and a hole in my trye

[beanzontoast]

Yes,that's a piece of glass,That'll learn you to gutter hug.

No need to hug the gutter to find glass - here in Derby, the glass can be found on any part of the roads on my commute. Nowhere is safe. It's on the streets outside the bars and pubs in town, on the cycle paths, in the side roads... Spend half my time digging the stuff out of my tyres. Front tyre's got more cuts in it than I've had hot dinners. I have to change my commuting route all the time to avoid the worst parts, and I'm sick of reporting it to the council, including trying to navigate the reporting system.

And if the glass doesn't get you, the potholes or debris from the road works will. Some of the roads round these parts should be reclassified as cart tracks. I honestly believe that with the glass and lack of upkeep together, the roads in Derby are the worst I've ever seen them - and this is a cycling demonstration town!

glass did me two days ago, I thought it was a nail, it was that long and thin and sharp, straight through the centre line of the tyre

this is as much an M+ tyres being whore to fit as much as tyre levers surely

I'm sure we've been promised they don't flat ...

 

[Plax]

That's a very clean chain and cassette you have!

I dont know if I can still keep the tyre as it now how a "hole" on in

 

[Keith Oates]

You may be lucky and can use the tyre for a bit longer but it does mean that the tube under the hole has no protection and will puncture more easily in the future. I would get the tyre changed as soon as possible, to be on the safe side.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[semislickstick]

I've wondered before about using superglue or similar in smaller holes, rubber glue?

Have used both in the past - neither lasts long. Once a tyre is cut, it's cut.

The tyre has exposed its protective rubbery layer (it is a M+), which it supposed to provide the protection.
If it is exposing the tube, then of course I know I will need to replace it, but now is a bit tricky

I'd be tempted to carry on using it tbh,especially as it's a M+.How much life is left in it tread wise? If it's fairly new then carry on until you're getting more p's than normal,if it's well used 1500-2000 miles+ then maybe get a new one.
I'll definately be buying more M+ when mine go,great tyre.

Not rubber glue - wetsuit glue and a bit of duct tape on the inside if you want a permanent repair. Run it on the back though so if it does deflate rapidly, you'll still stay upright. Probably.

I had my first mid commute flat last week. I turned a corner and had to ride over a pile of wet leaves (not in the gutter, beside some parked cars) when I heard a loud crunching sound. I thought it would be lucky if I get away with that.
100 yards up the road and I can hear air gushing from the tyre. Didn't find the culprit as it must have fallen out, but it was the biggest punture I had ever seen.
It was only when I stopped that I remembered that I had snapped one of my levers on the Friday night ride and I had forgotten to replace it. Changing a tyre with only one lever is not easy.
Someone on the Friday night ride used a set of Var tyre levers to help me, and they were really good. I think I'll put them on my Christmas list.

Do they hold a guarantee of any sort? We all expect them to be bullet proof don't we....or am I pushing it a bit?
