Tubeless - Sidewall Tear

[Super_mil]

Has anyone else had any issues with sidewall tears running tubeless? I'm running Michelin XCR Dry 2 tubless tyres (which have been really awesome rolling resistance and traction/cornering wise) on Mavic 819's but I had the sidewall of my front tyre tear on the way home from work on Monday evening, heading down the hill off Republic on the normal Spruit route. I hit the first ladder (over the marshy stuff) and hit the dip on the far side fairly hard, but no harder than usual and the front tyre tore along the interface of the rim and the tyre (right at the bead/sidewall interface). I don't think the tear was caused by a rock since it was almost behind the edge of the rim and there were no rocks and no damage to the rim. Fortunately I was carrying a spare tube which got me home.

 

 

 

So, what can I put the cause of this to? My first guess is that it was a tyre defect since I don't think I was doing anything the tyre shouldn't be able to handle.

 

 

 

Also, would it be possible to repear this and reuse the tyre or is it kaput? I'll try post some pics in the next day or two.

I've done one repair on a tire the beading or "tire/rim" interface as you call it using the dental floss / needle and thread / patch / superglue technique and it worked fine.

Depends on how long the tear is. I am very hard on tires and tear them on a regular basis. I just patch them up from the inside using a normal patch you use to seal your tube, I normally use a black patch I get at my LBS. R1 per patch. Lot cheaper then replacing my RaceKings every time i tear it.

What I do is clean the tire so that there is no sealant where you are doing the repair. Wait for it to dry properly, an hour in the sun should be ok. Patch it and then ( i know some will not like it) burn the patch for a couple of seconds. Put tire and sealant back.

 

Never had a problem so far repairing it like that. But his all depends on the length of the tear.

I also repair tears on sidewalls etc but one between the tyre and the bead ? But XTC has done it before so then it's most probably worth a shot .

Great, thanks for all the replies.

 

 

 

The tear is about 2-3cm long (if I remember correctly), so I'll give the repair a go and see if I can get it sorted. These tyres were pretty cheap from CRC so I won't feel too bad if I have to let this one go.
