Something like the DOT specs for load range and speed rating for auto tires, but applied to bicycle tires? It's obviously not relevant to bikes apart from tandems engaged in downhill racing. Perhaps not even that. This is an admittedly obscure question, but maybe there's an answer lurking somwehere I've not found. Probably manufactureres do it as part of design and production quality control, but whether results leak into the public sphere is unclear. I ask because I have a very nice bike cargo trailer (cycletote) which I've pondered attaching to a small motorcycle. It isn't something I'd do under normal circumstances, of course. Merely wondering what might be possible in a pinch. Thanks for reading, bob prohaska
