Blister on my tyre

The laminates breaking down by the looks and that blister could turn into stank slapper egg in time. Replace sooner than later.

 

Whoops predictive text, slightly different to what I typed!

 

Looks like a heat bubble, what pressure front do you run. could it be that you hit a large stone/rock and it has damaged the construction

 

I don't like the look of that at all. If that blows you will be in a real shit-storm of out of control bike. Get a new tyre would be my advice and maybe a different make/model.

 

+ 1 I would not trust it.

 

Ditto to biglads advice, change it, doesnt look like there's a lot left on it to be honest

 

I thought it looked to be nearly on the wear bars too !

 

Get rid, biglad is right accident waiting to happen I`m afraid. Better to be safe than sorry

 

Had a bubble appear once on my spare tyre, managed to find a bloke to repair it for me and it's been fine since.
Here's a picture taken just after the repair :-

 

FFS !!!!!!!!! What was that!!

On second thoughts PLEASE don't tell me.

 

If it helps, I found this on fleabay which is a Metzeler Z8 180/55-17
It has been advertised as Dunlop Z8 Intereact but is of course a Metzeler and atthe bargain price of £79.74

If you needa quick, inexpensive quality replacement

 

Looking at another forum, it appears this can happen when a tyre is under inflated and you hit an object like a pothole. This damages the plies inside the rubber, and ruptures the inner membrane.
Quite often the inside of the tyre is a lot worse as the bubble also forms between the membrane and the plies seperating the rubber affecting an area a lot larger then seen on the outside

In short...not good

 

'Looks like a belly button hernia to me

 

Rosso Corsa is a great tyre and is less than a second slower around a race track, they work even better on the road as they don't suffer as bad as Supercorsa's on heat cycles
