guys Posted January 5, 2013 Report Share Posted January 5, 2013 The title says it all I think. I had two cuts in the sidewall of my rear tire and tried to fix it with an inner tube. I did a testrun on my driveway and almost tore off the valve from the inner tube because the tire rotated a bit. Then I removed the tube, cleaned the rim and tire and mounted them. I poured about 10oz (300ml) tire sealant via the valve (removed the valve core) in the tire, inflated it rotated the tire for the sealant to contact the sidewalls and hey presto! tyre is sealed! It should last about 7 months and help prevent future punctures (up to 1/4 inch) Stan's Notubes tire sealant is very wel known by mountainbikers. My son used it on his tubeless mountainbike tyres and never had a flat, although he could be riding with thorns in the tires without him knowing it. If it doesn't hold I'll post it here...

copemech Posted January 6, 2013 Report Share Posted January 6, 2013 Cuts in a tire carcass are generally related to impacts, as compared to a puncture(round) and can be difficult to plug or repair as many times patches will not hold due to the flex of the sidewall and such. A dog turd may actually spread(open) a cut, making things more difficult. There is a US company called Safety Seal that produces a rubber bonding compund that is used with their primer to bond dog turds in place from the inside the tire that seems quite good stuff and should hold and seal forever on a normal puncture. My thoughts are this stuff is soo good it seems, it may well work even on cuts in a trials tire, if fairly small, as it flows in to seal the area, adheres, ans cures like rubber. Mind you, I have not tried it on a cut, but if anything will hold, this stuff should doo! Look up their website. I will try to find the link later. 1 Quote Link to comment Share on other sites More sharing options...
guys Posted January 6, 2013 Author Report Share Posted January 6, 2013 @ copemech: The cuts in my tire came from sharp rocks or something like it and the punctures were very small. Safety Seal http://www.safetyseal.com/index2.htm looks very promising. With other patches there's the problem that, besides the fact that the sidewalls of a trials bike flex a lot, you have to sand down or roughen the area around the puncture. If you do this on the inside of a Michelin X-Light tubeless tire, you will sand away the very thin layer of rubber that makes it air-tight. Also: The problem with other liquid tire sealant products is the fact that they leave a very sticky goo on the inside of your rim which is a bitch to clean of. That's why most tyre specialists don't like the stuff. Stan's Notubes tire sealant stays liquid and doesn't stick to your rim (you can get it off with water). And when it hardens after time, it forms something like little round balls, and doesn't stick to the rim. (No, I'm not sponsered by any of the brands! ) Quote Link to comment Share on other sites More sharing options...
