Edwin Watson Posted March 7, 2011 Posted March 7, 2011 Hey Guys Went to groenkloof this morning and had a awesome ride but right at the end i slid down a rock and my front tyre which is tubeless popped off and all the air escaped and some sealant. I was worried it was not going to pump back up but it did fine however 2 min latter it was flat again. While I was cleaning the bike I pumped the tyre up and put some soap around the rim and you could see air escaping. How do I fix this problem? Must I buy more sealant clean out the tyre and put new sealant in and then try mount the tyre again? I unfortunately don't have a air compressor and the only pump I have is a small carry one. The tyre went completely flat and I can still pump it up but so it must have quite a good connection besides the bit where it popped off. Or should I just take off the rim pump it up and then shack it from side to side until it seals? I am just worried I might not have enough sealant for this exercise. Or is there something I am missing all together? Thanks for all the info,its ALWAYS appreciated!
Unicycle Posted March 7, 2011 Posted March 7, 2011 Take everything off the rim, clean and fit the tyre with new sealant. You will however need a compressor to reseat, but any garage pump and adaptor should work. What tyres are you using? I have seen Vredenstein and Michelin pop of the rim - try Conti, Maxxis or Geax if it happens again.
AIRMAVRICK Posted March 7, 2011 Posted March 7, 2011 This happened to me about 6 months ago. Clean out the tyre put more sealent in and bomb it. Should get it to catch and then pump with normal pump. You will find thatit looses some air over a few rides but then after some rides and pumping it sealed it self perfectly.
CAAD4 Posted March 7, 2011 Posted March 7, 2011 Edwin most of us work on Monday mornings, so don't come here with your k@k stories man! We would also love to be out there while the rest of the world is working.......

I am currently running Kenda converted,are they no good? If I was going to ride in races I would be quite worried,the last time I went to Groenies I got like 2 punches and they would not seal.Worst of all it was right in the beginning however this could be because of my bad sealant. This happened to me about 6 months ago. Clean out the tyre put more sealent in and bomb it. Should get it to catch and then pump with normal pump. You will find thatit looses some air over a few rides but then after some rides and pumping it sealed it self perfectly.Thanks Mavrick,what sealant should I use? Should I spend the extra and buy stans or just that cheap green bottle? Edwin most of us work on Monday mornings, so don't come here with your k@k stories man! We would also love to be out there while the rest of the world is working....... Agg I wish I had a job! I have been at home for 3 months now,waiting for a contract job to start. I should be studying my international IT exams but I am just to lazy! Going to start soon and I will feel the same way you do Its very surprising how nanny cyclist's are out in the day,you don't realise it when you working but when you off for 3 months you kind of do! I just wonder how they make their moola to do it. happy cycling
Edwin Watson Posted March 7, 2011 Author Posted March 7, 2011 Hey guys,I took the tyre off my rim and cleaned both my rim and tyre of sealant but now there is a load of hard sealant around parts of the tyre,should I rub this off or just leave it and load the sealant back in with all this mucky stuff on the side walls. http://i152.photobucket.com/albums/s186/splinter_watsup/IMG_0899.jpg?t=1299507390 Also should I use Stans sealant or just that cheap grean stuff for half the price? And which adapter do I need to be able to pump up a preata valve at the garage Thanks again for all the replies and future help on this topic!
Edwin Watson Posted March 7, 2011 Author Posted March 7, 2011 Use stans. Never had issues with it.Thanks
Weight Weenie Posted March 7, 2011 Posted March 7, 2011 anyone any idea as to why the tyre came off? Depends as he doesnt say what tubeless system he uses. Normal rim with normal tyre it seems ? If it was a rimstrip I'm guessing low pressure together with a weak bead that does not fit the rim well meant it climbed off under pressure or if it's ghetto it was probly not seated well initially and came off under pressure. Anyone else care to hazard a guess ?
dirtrider Posted March 8, 2011 Posted March 8, 2011 You don't need to clean inside the tyre , just clean around the bead . You will find a tyre pop-off or burp when riding over very rocky stuff and ur pressures r a bit low or it is a new installation . After a few months you gonna need a serious set of tyre levels to get that tyre of the rim once the sealant has properly bonded the tyre to the rim . Where do you okes get punctures in Groenkloof ?

Anyone else care to hazard a guess ?Its was a ghetoo conversion,I bought the bike second hand with the conversion already done.The seller did mention that he did it using a BMX tube so that if a spoke breaks or something he wouldn't have waisted on rim strips. The sealant was also green so(to my knowledge)Is not Stans and most certainty doesn't work like it! You don't need to clean inside the tyre , just clean around the bead .

After a few months you gonna need a serious set of tyre levels to get that tyre of the rim once the sealant has properly bonded the tyre to the rim . Where do you okes get punctures in Groenkloof ?I was riding on the very rocky bit at the end where you ride down accross the stream just before the new wooden bridge and it burped all the sealant out in two places. I got home grabbed 1 tyre leaver went out side and it took me about 5 min to dismount the tube. There was a fair amount of sealing around the tube to rim but was not like you mentioned however this is probable due to using the cheap green stuff instead of stans.
Just Keep Pedaling Posted March 8, 2011 Posted March 8, 2011 "Its was a ghetoo conversion" UST tyres are much tighter around the rim to prevent this. Depending on your weight you should pump Ghettos harder than normal to try and prevent this. Note: if it comes off at high speed be prepared for some pain.
Tubeless Posted March 8, 2011 Posted March 8, 2011 which adapter do I need Over the weekend I bought a cheap adaptor at Sportsman Warehouse. http://4.bp.blogspot.com/_ftJqHS4aWPw/TAgKDodD9eI/AAAAAAAAAJo/87xU5NNgA0Q/s1600/valve+adapter.jpg
Weight Weenie Posted March 9, 2011 Posted March 9, 2011 I keep one of those adapters screwed onto both of my bikes, so I can use a garage pump if in a pinch on a ride
