Plentipotential Posted February 5, 2015 Posted February 5, 2015 Well you have a great set of rims IMO. I run Mavic 819's and following your question about tyres I use Conti. Race King on the back and a Mountain King on the front with SlimePro sealant and I have not had a flat yet in 4 years! Nice thing about the slime is that it does not stick to everything making the clean up prior to a fresh application easy. Remember to smear a bit of vaseline to your valve to keep the slime from sealing it. I run 1.1 bar up front and between 1.1 and 1.2 in the back, I am a featherweight at 95 kg's. Slime Pro Tubeless Sealant.jpg How and where do you put the Vaseline on the valve ? Remove the valve core from the valve, I use a pair of long nose pliers, small smear of Vaseline on the fingers and then just rub it onto the end that fits inside the tyre. You can see where the seal is, black bit in pic. and you need to keep the slime off of that.
SwissVan Posted February 5, 2015 Posted February 5, 2015 They are rocket rons, and it says tubeless ready on the tyre. The leaks are all over, pretty inconsistantThe tyres were brand new, and they are rocket ron, tubless ready.. Tubeless ready is not 100% tubeless, it just means the bead is suitable for a tubeless installation. Do a soap n water test with max allowable pressure to see were the leaks are, look very closely as the wont be that obvious. If its a few small leaks from the rubber with no apparent hole then its normal with a lightweight tubeless ready tyre. Learn from the Stans support videos how to sort it out yourself, saves you going to the LBS ok then it sounds like your lbs did a rush job to fit them. either return the bike to them to install properly or learn to do it yourself: https://www.youtube.com/watch?v=9RzASr-cPPs You don't need new tyres, just a bit of patience in the sealing process.Make sure you do the horizontal swish and shake routine a few times then just ride them. They might loose a bit of pressure overnight between rides From Stans website:Video: watch after 3 minuteshttp://www.notubes.com/help/index.aspx http://www.notubes.com/help/troubleshooting.aspxPin-hole leaks in the side of my tireStan's Sealant will fill all holes left in the tire from the manufacturing process. Some tires, especially lightweight tires may develop new pin holes in the side walls during the first week or two after inflation. It may be necessary to repeat the sealing process several times. Some tires may also have tiny rubber bubbles, often near the raised letting on the sidewall of the tire than need to be broken and sealed or they may pop overnight and leak air on their own.Tire not holding airCheck for leaks with soap and water. Use a smooth sheen of soapy water as to not create suds, but allow the air leaks to create suds. Shake sealant to areas of the tire where soap bubbles occur. If using Stan's rims check the yellow tape for proper installment and any holes or cuts. If using a rim strip check the strip for proper installation and holes or cuts.
nonky Posted February 5, 2015 Posted February 5, 2015 yip, first hand experience. my current setup includes a raceking protection at the rear and it took about 3 weeks for the sealant to work its magic and stop the sidewalls from leaking, which you can see as the sealant forms little "sweat" beads along the sidewall.Thanks!What impact does the sidewall leaking have - pressure loss only?How hard are the protections to fit on rim, seat and inflate? Can you do it yourself?
karlito Posted February 5, 2015 Posted February 5, 2015 Would love to know why this is happening. I converted my rocken ron's (not snakeskin) to tubeless myself at home and no issues. Used two cups(stans cup) per tyre, inflated with floor pump. Syncros xr2.0 rims, had no need to use rim tape just put in tubeless valves.
fanievb Posted February 5, 2015 Posted February 5, 2015 Thanks!What impact does the sidewall leaking have - pressure loss only?How hard are the protections to fit on rim, seat and inflate? Can you do it yourself? loss of pressure and sealant, and you only realise you are short of sealant when its too late. fitting is the same as "regular" conti's
Skylark Posted February 5, 2015 Posted February 5, 2015 no, the protection version sucks and leaks through the sidewallsContinental tyres of many varieties are notorious for leaky sidewalls, are the tubeless specific ones not leaky?

Adrian Fogg Posted February 5, 2015 Posted February 5, 2015 Could also be loosing pressure through the nipples of the rims, my 2cents before you put on the rim tape. Place some insulation tape covering all the nipples and then add the rim tape.
GoLefty!! Posted February 5, 2015 Posted February 5, 2015 any tyre can leak. Simply add enough sealant agitate the wheel to get teh sealant to the problem areas. Agitation could also involve having your wheel open a Hub account
ChrisN Posted February 5, 2015 Posted February 5, 2015 I recently did my first successful tubeless conversion. My first attempt was with continental x kings, and Ryder latex sealent. It was a complete disaster. The sidewalls leaked a lot and the sealent clodded to one single ball of fibres. My second was with maxis crossmark and merida race-ready tires, both non tubeless tyres. I used the cheap ryder slime sealent. The one with the small rubber pieces in it. This worked perfect. Both hold air like I expected. The biggest mission was to get the tyre beaded the first time. I used the air hose at the garage. I know there is no way I will be able to re-bead them in the veld.
Skylark Posted February 5, 2015 Posted February 5, 2015 Co2 cannisters will seat a bead out in the trails or at home for that matter. They are getting quite pricey these days though, the 40g or so sized ones they recommend for 29ers sell for around R50 at some lbs.
MphatiPyga Posted February 5, 2015 Posted February 5, 2015 What is a good pressure to get a tyre seated? Looking at getting a 12v compressor for a little trip up to the Okavango, but would be good if the same compressor could work on my MTb. Any ideas?

Any ideas?Mine has seated many tyres tubeless, some with a real struggle though and with some tyres the only way is with a normal compressor. Suppose it depends on the 12v compressor you buy, they get damn pricey but most have no tank and limited cfm/air flow capacity.
GoLefty!! Posted February 5, 2015 Posted February 5, 2015 the max rated pressure for the tyre, aggitate and leave over night
