Tubeless repair

[Lwatson]

Anyone on here tried to repair tears in UST tyres?

I've used standard puncture repairs kits for some holes previously but i have tears on the sidewall that dont seem to take the patches too well.

Is there a thread you can buy; to stitch small tears? I think Ive seen it before, but not honestly sure :confused:


Any thoughts?

New tyre I'm afraid!!! What happened, lend a wheel to Speedfreak? ;)



But seriously, how big is the tare? Do you use sealant? I'm thinking plastic + super glue and sealant in the tyre.

I know not to lend anything to him after the mess he made of yours!

Yeh, i use sealant.

One tyre has a small slice where the rim come in contact with the tyre, its about 1/2 an inch. Me other tyre has a slice on the side wall about an inch.

What about that stuff above?

Get the Panaracer tubeless repair kit. Works a treat on anything under 3mm. Let it set over night and you'll be fine.

Are you using any wheel milk?

125ml in each tyre, no good for the holes i put in them!

**** one. I holed a brand new Racing Ralph within 5 mins of hitting the first bit of singletrack a couple of weeks back. 100ml of tyre milk didn't help as it would only hold about 20psi. The new one is going great though.
Rob, I will never go back to tubes after changing to UST 3 years ago. The pros more than out way the cons. I've only had 3 punctures in that time!

You have just scudded yourself now Paul.

Tubeless is the way forward I'll not be going back to tubes anytime soon.

I've used the Weldite (http://www.justridingalong.com/?product=81) repair for a tear that wouldn't seal, in the tread of the tyre. Still in there 3 months on.

That tubular stitching repair might work to hold tyre together (leave a decent edge distance when stitching, so it doesn't tear out), then put tubeless patch on top.

[Lwatson]

Weldite kit and thread ordered along with two new high rollers for the weekend :o just incase.

Rab, cheers for the lend of the swampy today, still all in one piece so your not getting a new one off me :p

[Pauly]

I hope not Rab, as I'm racing in the Charge Set2Rise 12 hour night race next weekend!
How's you anyways? Is the wrist better?

Use a big tube patch i.e. one designed for vehicle tubes.

Scrub the inside of the tyre to get any latex/residual gunk of the repair area (ideally using buffing compound - don't use any abrasives, as you're likely to go through to the tyre cords), then apply patch just like you would to a tyre.

Then leave it to cure for a while, and check it's stuck.

For the appropriate materials (big patch + buffing compound), go speak to your friendly local tyre fitter.

i patched a one inch rip in the side of a nobby nic ust.

there are proper tyre patches,bout same price as tube patches.

was bit thicker and larger,just stuck on sidewall,left to dry, and that was it.

think i got them from justridingalong.com

Is that like a tire boot?
I've a couple of park tire boots in my road bike saddle back as I have slashed a tire badly enough more than once for the tube to bulge out through the hole when you pump it up :o

[mc]

The park tyre boots aren't really ideal, as they're just designed to just stick to the tyre, and not vulcanise into it.
A proper patch with glue (it's actually cold vulcanising solution), creates a far better bond/seal. Then some tyre sealant will seal up any remaining leaks from the patch - due to the thiness of the sidewalls, it's unlikely you'll get a perfect seal with a patch alone.

[bob8925]

not a tyre boot,its just like a thicker patch

[Lwatson]

Needle & Thread arrived today along with patches etc.

Repaired 30mm tare on sidewall, stitched it and covered in super glue on the inside, back on rim with sealant and not a hiss :)

tubeless is the way forward
