I'd also recommend the Maxxis tires, have had great luck with mine. As for deflection, part of the reason ST tires don't have as much deflection as LT tires is because the ST tires are designed to be scooted sideways when turning and backing so sidewalls are generally stiffer to keep tires from rolling off the rim, thus the higher weight rating of ST tires. Manufacturers use STs predominantly for a reason, and its not so you'll have more blowouts. They just haven't made good choices in the brands that they use. I've seen LTs used on car trailers and when they turn it looks like the tire is ready to roll off the rim...not a pretty site for sure! In my opinion, a lot of people use the LTs just so they can run as fast as they want without having to worry about the speed rating on the tires. Of course some will argue that comment too.
Experiënce with ST tires is that they blow more often then LT tires, let it be 3% instead of 1% , so the gross of TT users drive without problems. And those cases are written down in fora, so it looks a lot.
My conclusion of ST tires is yust that they deflect more, if you put the pressure in acording to Pressure/loadcapacity lists.
If you always put "Maximum"pressure in as often is adviced by TT makers , you give the tire for the lower load then maximum load, a lesser deflection.
And a stiffer sidewall produces more heat at the same deflection , and sertainly at that more deflection the ST tire has when filled to P/LC lists for the lower speed they are calculated for in their maximum load.
The tires wont come of the rimm by the more sideward shifting, that only happens at a pressure of below 20 psi, and then not even on the nowadays rimms with 2 humps on them to prefent that.
In the 1980s I read a story about a Canadian vehicle that could drive over the yust unfrosen mudd. Remember GVW of 10000kg/22000lbs, and a tirepressure of 0.8bar/12psi? and a special construction of the rimm to prefent the tires from going of them in curves. Think that special construction to be that 2 humps( 2 times PANG when tire mounted to rimm) wich where not always used in those times.
Question to KBOntheroad, what pressure do you keep, always "maximum cold"of tire or going from P/LC lists.
Mayby there the difference is , that OP uses second and you first.
But also for LT tires its better to give them a deflection that dont produce to much heat.
The tire on the pictures of OHIO Engeneer, are tore at the overgoing from sidewall to treath , where they bend the most so produce more heat , and so that ring is probably getting to hot.
To my opinion a to much deflection for that tire and speed related damage.
