The tires sat for months without being exercised. That allows a set to develop in the sidewalls and the oils in the rubber to leach out where it contacts the ground. The tires should be allowed to roll about once a month so the rubber gets to distribute the oils and there is no spot where the sidewalls can harden. Those brittle spots can allow more heat to be developed in the areas leading to sidewall failure.

The second issue is you are starting out with low pressure. The pressure should have been 125 PSI cold when you start. Do not concern yourself if the pressure rises above that point when the tires warm up. That was taken into account by the manufacturer. Starting out with low pressure causes excessive flexing of the sidewalls that are already weak due to sitting a prolonged time in one spot.

Finally, have you weighed your rig to see how much it weighs? Are you traveling with a full fresh water tank?
I thought G614's should be inflated to only 110 psi cold before traveleing. Where did you get the 125 psi figure?
