No. They didn't.
Firstly, ...you don't "get" a TSO. A TSO is a Technical Standard which a manufacturer must MEET in order to make the claim.
Secondly...THIS PRODUCT is not yet mfr'd to that standard according to the advert. They hope to do so by late Feb. (The question is... Will they?)
One more thing about Desser Tire. I like them. But do not recommend their 90-degree brass Schrader-valve inner tubes.
I ordered two of them. They both damaged my Cleveland wheels by creating a sharp edge at the Schrader-valve opening which subsequently cut ordinary inner-tube valves causing the regular tubes to leak and fail in an unrepairable fashion. Also, the 90-degree angle does not exit the wheel as advertised/anticipated/promised. Instead, the valve lays hard against the wheel-rim making it almost impossible to re-service the inner tube with air because a common air-chuck cannot fit upon the valve due to interference with the wheel. Even a moderate effort to fill the tube with air SNAPPED the brass Schrader valve completely at the mid-point bend! (In my disgust, I reverted to the installation or regular rubber Schrader-valve tubes, ...the first of which immediately leaked due to a cut valve. Further disgusted (and not discovering the sharp edge caused by the failed brass tube) I removed it and installed another, ....which promptly was also ruined with a cut. The cut was virtually invisible, as if made by a razor at the base of the Schrader valve.
Upon very close examination, the sharp edge was discovered on the inside-surface of the wheel's Schrader port. Careful dressing of the wheel with a small Swiss file was necessary to remove the damage within the passageway.
A third inner-tube was finally installed with success.
Moral: The 90-degree brass Schrader inner tubes are not suitable with Cleveland wheels as they do not properly exit so as to be re-inflation serviceable, and their design can create a sharp edge which could seriously damage the wheel.
