Mawbs Posted July 28, 2014 Posted July 28, 2014 So this weekend i got a cut in my brand new Nobbly Nic. To big for the Stans to work but i hope to repair it . So it's on top of the tire ( not sidewall ) and is sort of an L shape. Can someone advise me the best way to repair it so i can save the tire and remain tubeless
Super Sywurm Posted July 28, 2014 Posted July 28, 2014 As far as I know, if your tire gets a cut, you need a new tire. I am able to plug a small hole, but I can't fix a cut.

Get a kit at your LBS...most of them have...also carry with you when riding
dirtrider Posted July 28, 2014 Posted July 28, 2014 It all really depends how big the cut is and how far the hole opens up when you inflate the tire . Have done a few sidewall repairs with a normal patch , solution and a bit of nylon tread .
JA-Q001 Posted July 28, 2014 Posted July 28, 2014 You should be able to patch it from the inside with one of the older type car tube patches. (Those that has the red base and black top) Remove the tire, clean the area around the cut properly (on the inside) and allow to dry completely. Then take normal patch glue and apply generously to an area larger that the patch and allow to dry. then add another layer and allow to dry, until tacky. Apply the patch and heat it with a hair dryer, while applying pressure. when nicely heated, then clamp it in between something (like a vice and 2 peaces of wood), then leave overnight. It should keep it properly airtight after that. After remounting, pump the tire and check how much it opens, then fill the gap with some black silicone and allow to dry properly. That should fix it.

Skylark Posted July 28, 2014 Posted July 28, 2014 As long as you have a patch that completely covers the cut with around 10mm on either side, maybe even try a car or motorbike patch if a mtb one is too small. As long as the patch has been correctly applied all it will add is a little bit of weight. Once the tyre is inflated the air pressure will be holding the patch onto the inside of the tyre so the chances of it coming off is slim. Just make sure it is properly applied, clean/dry that part of the tyre inner, roughen and then apply glue and then take a hammer or similar and softly hammer on the patch once it's applied to make sure the glue has bonded properly all over the patch.

Mawbs Posted July 28, 2014 Author Posted July 28, 2014 yep it's to big ( funny L shape ) for a plug i think so i thought the patch on the inside would be the deal. Thanks for the advice will give it a go tonight

Thanks for the advice will give it a go tonightGet a plug for a motor bike or car tyre. They are bigger than the ones made for MTB and work great on the bigger holes and cuts.
camelman Posted July 28, 2014 Posted July 28, 2014 (edited) I have tried to patch a sidewall cut from the inside. It got me home but the bulge of patch sticking out though the cut was too much so I had to ditch the tire. Maybe if there was a patch that did not stretch(with some reinforcing) it would work. Anyone seen those? And please do not try to patch the inside and superglue the cut on the outside. Superglue and rubber solution are mutually exclusive. You can throw away the tire after that experiment. I have done it so you don't have too. Edited July 28, 2014 by camelman ValeYellow 1
Captain Fastbastard Mayhem Posted July 28, 2014 Posted July 28, 2014 Stitch it together with dental floss (the waxed variety) - No, I am NOT joking - and then patch it with a thick, large patch from the inside. The Dental Floss will hold it together properly, and prevent the patch from trying to force itself out of the gatjie in the tyre. it'll be a lot stronger than a patch by itself, and if you do it right the floss won't come undone until the tyre is well past its sell by date. Ridden like this for quite a while on my old rear tire and it lasted VERY well. fanievb and MeridaHFS 2

ValeYellow Posted July 28, 2014 Posted July 28, 2014 (edited) Step 1 - Remove tyreStep 2 - Throw tyre in the binStep 3 - Take a drive to your LBSStep 4 - Purchase Maxiss Crossmark tyresStep 5 - Refit tyre and never worry again Jokes aside, I think that doing a repair job is going to give you endless drama. I ride a Crossmark at the rear and an Ardent up front - my riding style is pretty aggressive and I have taken them tyres where no tyres have gone and they keep asking for more - b omb proof combo Oh, Chris Willemse Cycles has them on a great deal, check it out - http://www.cwcycles....k-ust-29er-tyre and http://www.cwcycles....ust-lust-29x225 EDIT: yes they are a little on the heavy side, but run them tubless, small price to pay IMO Edited July 28, 2014 by ValeYellow
