Alurim's alloy wheels

[tlmark]

Hi

Ive only had my A10SR for 5 days and on my longest ride so far 30 miles I picked up a nail in the rear tyre (see Pic)
only thing is the tyre still hasn't gone down?
It's been a while since I had a bike with inner tubes but I always remember they went flat straight away if punctured. the tyres are Avon road riders (Tubeless)
Now my bike has alloy rims made a company called "Alurim" made in England, I was just asking to see if anybody knows of them and if they could be tubeless rims?
I can find nothing on the net at all.

Well the offending nail has been removed. As I'm not sure if it has an inner tube I thought it worth using my tubeless repair kit and plugged the hole.
And so far it's holding air tight?

G'day tlmark.
A tube has the steel valve stem with a nut, the tubeless valve stem is rubber and fatter as it enters the rim.
There are methods these days to seal the spoke nipples to allow tubeless tyres.
Here's a cheap DIY method.  http://www.dotheton.com/forum/index.php?topic=64367.0
The valve stem looks like a tube type from the outside.

You can get steel tubeless valves as well so that's not a foolproof way of telling

That is right Kickaha, the one shown at the bottom of the dotheton link is like that. I hadn't seen one.

Well 24hrs later is holding pressure so I guess the rims are tubeless or have been modified to run tubeless tires? 

To be honest I'm glad as fixing a tubeless is so easy these days and takes a few minutes and the type I used, I've tested on 100hp+ sport bike no problem.

my local dealer bins all tubless tyres wont do any repairs at all a honda fireblade with a screw in middle of rear tyre tread  was binned done 11mls

The externally fitted plugs are only a stop gap to get you home at a max speed of 140kph (that won't worry us). The only way to do it properly is to patch it internally, just like patching a tube.
A few years ago I borrowed a mates R1. I got her up to 285kph. When I told him he freaked. Not at the speed but said the front tyre had a plug in it! So they might have a safety factor of 100% or I'm very lucky.

He's being very conservative but there is only a narrow area either side of the centreline where a repair is suitable in tubeless and only up to about a 2mm hole (over here at least)

There is also a plug/patch that can be installed from the inside. None of the fixes are foolproof, and I've seen all fail, but I don't see that as any different in effect than puncturing a new tire.
Question: if you pulled the nail and it was holding air, why did you install a plug? Either the nail didn't penetrate the carcass, or there is a tube that wasn't punctured. Installing a plug requires enlarging the hole, and if there's a tube, you run risk of damaging it when installing a plug. Doesn't make sense to me, so I'm curious about your logic.

In the interest of safety I am going to have to chime in here.

tlmark your tyre has a tube in it. Before you ride the bike remove the tyre and replace the tube even if it looks ok. You may get away with the tyre if you cut the plug you have installed off flush inside the tyre and put a patch over it on the inside.

You may have damaged the tube and if not the plug you have installed will over time.

It is a very unpleasant experience having a tube deflate rapidly while riding a bike and could cause you to have accident.

Hi Timark, I'm with Brian in this and think you need to be 100% certain you do not have an inner tube as a matter of safety, it seems you probably have, and this almost certainly means having to remove the tyre.

Unfortunately when you buy a bike you often waste time finding things out the previous owner has done, and it will be annoying if you find it has a tubeless set up 

Nothing worse than taking a high speed bend and whilst cranked over things like "will the puncture repair hold out" pop into your mind!

The previous owner could also have fitted an anti puncture tyre sealant which could explain why it is not leaking, "Slime" is the name of a common tyre sealant here in NZ.

If they fail they weren't done right, I've done hundreds if not thousands of them (primarily car tyres) and done properly they will last the life of the tyre

Any tyres that has had a puncture should be removed and inspected, it easy to damage them by running underinflated and that won't be obvious from the outside

[tlmark]

I have checked and its tubeless alright (thank god) 

these plugs are mushroom shaped so they cannot come out once installed (the stop and go system)

I was actually recommended these by an AA man who rescued when my Ducati had a puncture. And now carry them in my rucksack all the time.

I do understand some of your concerns but these plugs are superb

Why doesn't the air leak out of the spoke holes?
