Tyre leaking from the bead?
« on: February 22, 2021, 10:57:40 am »
Put some Karoo streets on in December. No issues.
Did a trip to Sabie.  No issues.
Did a few rides over Chirstmas/new years, no issues.

Then for the last 3 or so weeks, I haven't had a chance to ride, Bike sat.  Took it off the centre stand on Friday and the front is completely flat.  No sign of a puncture. pumped it up and gave the bike a wash and noticed it's bubbling out from between the rim and the tyre in multiple spots. Rim is fine, no bends or anything.

Any way to fix this?  Was basically flat again by Sunday afternoon. Could it be from not riding somehow?

Remove tire.
Clean bead and tire bead-seat properly
Refit.
Inflate.

We have found on occasion that k@k somehow enters that area and causes deflation - ie wet sand/ mud gets into the bead, but does not initially deflate the wheel. When it dries out, it creates the perfect gap for air to escape.

Just a thought.

Ok I'll give it a bash.  Was wondering if maybe there was a Karoo Street issue but no evidence of it on forums...where okes usually moan about stuff, :biggrin: so I'm sure it's something like that.

Of course it can Stu: leave it for a decennium or longer and rest assured the tyres will be flat!
No, don't thank me, and also no, I won't wait for your post checking me on this  :P

You didn't go ride some dirt skelm somewhere alone did you?
Fooi man, you got my number...  ;D

Yip, take the lot off (tyre OFF rim!), wash & scrub the lot, let dry, then inspect minutely to see if you can spot some leakage potential.
On my 300 (with Tubliss system) I found out that the tyre's bead had thousands little moulded radial ridges (NOT a tubeless tyre mind!), and this caused the tyre to leak slowly.... so I had to put another new one on, this one not having these ridges.
Your tubeless tyre won't have these, I only mention this because one has to have a genuinely good look, I missed them during the first quick-fix attempt to repair  :(

With an 8week old baby, any riding currently a quick sneak off if I see mom and baby are asleep on a Sunday morning unfortunately!   But soon!!! 

I am thinking about going back to more knobblies anyway, these streets are a bit scary in sand and mud.

I've found this to be an issue only with Mitas E07's on both front and rear of my 1150,  and it's a mild PITA.  Been back three or four times to the supplier - Neptune Tyres PE - and they have been patient and persistent, removing tyres cleaning and inspecting minutely and water testing after re-fitting. No leakage apparent, but I can still expect to lose at least 0,5 bar over a week.
They tell me I'm not the only E07 customer with the problem. I'm just living with it........ :-\

Same problem with EO-7 on the front on my 1150. Took it back, rim corroded. Never happened before. We reckoned it was the muti they used to slide it on. Cleaned and used non-water based this time. Seems to be holding.

My rims were never porous with Annakees. Would hold pressure between each check most of the time and only need the occasional puff.

Remove tire.
Clean bead and tire bead-seat properly
Refit.

We have found on occasion that k@k somehow enters that area and causes deflation - ie wet sand/ mud gets into the bead, but does not initially deflate the wheel. When it dries out, it creates the perfect gap for air to escape.

Just a thought.
Remove Karoo street’s and replace. Worse tyres ever. If you off road and get a puncture they are impossible to plug. Karoo 3s great but streets are kak

I actually only bought them for a 98% tar trip I do every year in December. And they handled that, and a VERY wet ride home very well. But yeah when things get sandy they're a bit scary!!
