Blowing tires on 5th wheel

On the days you have tire issues was it a hot day and you had reduced the inflated pressure, of the tires blown did they have abnormal tread wear or uneven across the face, had you checked the tires each 60 miles by putting your hand on the sidewall for hot sidewalls or had the tread separated from the casing? Does the trailer sit level on both axles to equalize the weight, what position on the trailer did they blow or it didn't matter? Have you hit many curbs/potholes or scrubbed the sidewalls on corners? This is not a smart ass answer but the very basics in investigating causal factors for tire failure and pertains to all tires despite brand or manufacturer.

Thanks all for your inputs getting some good ideas and advice.

All of the blowouts except one was on days over 90 degrees. Blow outs have been from different positions. Tread on all is almost new like. No uneven wear. All have been side wall blowouts. Some rough roads in some of the travels but mostly highway. No curb hitting. Did not stop every 60 miles to check sidewall temps. When my truck is hitched it only goes down 2". I have not checked to see if rig is level when hitched but truck does not have lifters or anything so is at standard height.
