Higher load range tires would actually make it safer, not just make it "feel safer", and I did not imply that heavier springs and/or higher rated tires would make the combo legal.
People are going to do want they want, no matter what the weight police say - otherwise there'd be no weigh stations. Pointing out the OP may want to consider higher load range tires adds another $1200 in expenses that may or may not change his outlook on the truck or trailer. I appreciate the weight police for keep reminding us of the rules though, however human nature causes us to frequently overlook rules and risk.
And insurance is paid so we can do dumb stuff, when human nature takes over. Not that I would or would recommend anyone else driving illegally for fear of causing an accident, injury, or death.
