You should run the max pressure if the load is at max for the tire. Running 15 PSI under max when you have loaded the tire to it's maximum weight capacity means you have just underinflated it. Per the tire rep, the tire runns coolest when it is not flexing to an excessive degree. Under inflating it means you are allowing the tire sidewalls to flex more than if you are at the maximum pressure listed on the sidewall before you start out.

Hoping your tires warm up enough to bring them up to the proper operating temperature by flexing has just put excessive wear on the sidewalls in the process. That's asking for a premature failure. I trust the folks who designed, tested and manufactured the tire to know their product and operating procedures far more than any one who does not have the credentials or testing procedures on the product.

Inflate the tires when cold to the proper pressure before you start out and leave them alone during the drive other than to make sure they have not lost pressure and are getting hot. Check and adjust as needed cold the next morning before you start out again.
