Warranty Disclaimer
 |
The use of any brand other than SCHWALBE's "self-sealing" products and/or aftermarket "sealant" systems for the purpose of converting a non-tubeless tire to tubeless, used either on non-UST rims or UST rims, will void any warranty given by the tire manufacturer. |
|
The use of any brand other than SCHWALBE's "self-sealing" products may over time degrade the interior wall of tires, especially non-tubeless tires, resulting in a blistering of the tread and surface layer on the exterior of the tire. This is not a manufacturing defect but the result of an incompatibility of the sealant with the rubber compound and therefore not considered a warranty issue. |

use of self sealing products with a tubed tire
Umm how come I have never experienced this with any other tire??
Not limitied to Schwalbe tires
The failures have happened with other brands. I have seen Conti, Kenda, Schwalbe and Nokian tire casings fail when run with Do-It-Yourself (DIY) tubeless methods. Does not happen with all tires or all users, but it does happen.
Going Tubeless
It appears that a rash of physical tire failures does correlate with the use of tubeless conversion; but why? Everyone should know that a high correlation does not indicate a cause and effect relationship. I suspect that these failures are not caused by the "juice," but rather by running lower inflation pressures than the tires are designed to accomodate.
Warranty Disclaimer
If you have your tires long enough for "blistering", or delamination to occur...you are not riding enough! I have used conversions since Dec.2003, and have never had an issue, except with a M*xx*s Crossmark, which had a whole batch of bad tires. Oops, that would be all of them...
Anyway, as far as Scwalbe is concerned, I think the disclaimer is just a precaution against law suits, right? I know of people mixing their own sealants, using all kinds of epoxy gells even....

You state that "The use of “self-sealing” products and/or aftermarket “sealant” systems for the purpose of converting a non-tubeless tire to tubeless, used either on non-UST rims or UST rims, will void any warranty given by the tire manufacturer"
If that is the case then why is Schwalbe in Germany and the UK using Doc Blue, a Schwalbe product used for sealing tubeless systems. The product states it will seal holes in tubes, tubulars and tubeless systems which sounds to me like it is universally friendly to all tire types.

Don't do it
Ain't no BS. One of the guys on the team was running stans and double flatted in a race. The tires were blistered and shot with hardly any miles on them
If the sealant has Ammonia in it
"stans", the sealant will eat away at the bonding agent that holds the tire casing together. Cafe Latex, ProtectAir, Slime, Superjuice do not have ammonia.
non-Schwalbe sealant tire degradation
Has anyone thought that much of this concern about blistering has to do with use of tube tires as tubeless and has nothing to do with the sealant component(s) "degrading" tire material? I have had this happen to a couple of Specialized tube tires over the past couple of years, but attribute it to the ability of the inflation air to have "direct access" to tire material of a tubed tire. Had a tube been installed, the interior tire layers would not have been exposed directly to high pressure air, thus the blistering would not have occurred. Since I chose to use a tube tire in a tubeless application, my fault, my risk. That said, the blistering happened only after many months of use. Perhaps it is worth considering removing most or all of the air from tube tires that are being used tubeless during extended periods of non-use. Of note, I ride over 2,000 miles per year, about 30% on roads and 70% off-road.
self-sealing
It reads "The use of any brand other than SCHWALBE’s" so their own brand should be fine.
That is a mainenance issue
Anyone that starts a race with tires that are "blistered and shot" does not take racing seriously, as he did not prepare his equipment before racing. Taking equipment like that on a race course makes me believe that your racer probably has a lot of mechanical problems that he blames other people for, but are totally avoidable. Winning races involves hundreds of hours of your OWN maintenance. I have run two years of tubeless with only one flat, which happened after the race due to a massive tearout.
I don't mean to be offensive, I just want to note that a lot of racers point fingers. If you want to run a system in a way it was not designed (i.e. a lighter configuration) you have to inspect it every single time you ride it, and take responsibility for your own setup.

Doc Blue
Thanks for pointing out this oversight. Doc Blue is of course also available in Canada and the U.S.A and formulated to not react aggressively to rubber. The use of Doc Blue will certainly not void the manufactures warranty and Schwalbe will fully guaranty the compatibility of this sealant with its tires.
The Warranty Disclaimer was obviously written before Doc Blue was available to the market and we apologize for the oversight in correcting the statement.
