Is anybody aware of testing results for the speed, load and 
temperature limits of bicycle tires? 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,
