Multiple blowouts in short time

Thanks guys for all the suggestions thus far. So yes this set we've just installed I told the guys to balance. I've always been told at the tire shops to not worry about balancing but this time I told them to do it anyhow. I've weighed the trailer when I first registered it in Texas but that was only front and rear, not side to side. I'll check the equalizer links and alignment. We've checked the heat on the tires as it rolls through them on a constant basis and even on a hot Texas day when one blew last, the tire temp was in the low 110's while underway. It would only get higher than that when we'd stop for a break, then they'd get to about 120. The air temp was registering about 103 at the time. I like the spotter/go pro idea.

Thanks!
