Does This Tyre Need Replacing?

Secteur

Hi, both of my Durano's have multiple "nicks" in the rubber, in several cases I can see the blue kevlar belt which doesnt appear to be penetrated (though it's hard to be sure).

I've not had a puncture, or any other problems.

Should these be replaced?

Thanks

Personally... I would...

Naaaah. They've got thousands of miles left in them.

As long as you don't compromise the structure of the carcass you'll be reet.

If I changed my tyres every time they looked like that, I'd be having a new set every month.

I do draw the line at this though:



I could see the damaged threads on the carcass on this one and it was bulging there when pumped up.

Stick a tyre boot in and get on with it. Thousands of miles left in that!

Looks ok to me. My Durano plusses look like that after a bit of grotty winter road action, never been a problem.

Not all that easy to see but from the looks of it it's not bulging and although you can see white (the threads of the carcass) they look to be in tact.

I don't worry about anything unless I can see the inner tube. Take it off and have a look from the inside if you're unsure.

'tis but a scratch

i replace if there's a cut that penetrates the carcass big enough to cause the tyre to bulge or allow the tube to work through

Hi all,

yes the kevlar belt seems intact and I certainly cant see any innertube and there's no bulging.

I have heard people talk about superglue? - should I use that? if so, how?

Its a nylon belt I think. Deflate Tyre, stick some super glue in the hole, press it together on the edges of the hole so they stick together and wipe off excess super glue

That's embedding something hard and sharp into the tyre. Never seems that useful an idea to me. I've generally not noticed cuts growing much on their own and the likelihood of an existing cut being more likely to pick up a new shard of glass or whatever and causing a puncture that the glue would have avoided seems slight to me. I think you are better off keeping an eye on cuts and regularly making sure that they are empty of glass rather than filling them with a substance that is kind of like glass!

+1. I've never subscribed to the superglue idea. It's the carcase that holds the thing together. The tread is meant to be sacrificial.

No, unless you are Richie Rich.

I don't change the tyre on my traning bike untill the tube is poking through, or it keeps getting punctures.

No, it's as new

Would it be worth filling the hole with puncture patch glue? Presumably that stays rubbery...

Good question... Does anyone know?

Waste of time. It won't hold in place. Leave the cut, I have dozens of cuts on my tyres and I puncture less than people with no cuts. If the tyre got cut and did not puncture, it's a good tyre, a keeper!
