I had the Firestone Transforce 245/70R17 tires provided by the factory on my truck. They were good tires in terms of handling, load capacity of 3195@80 PSI, good tire life, and very quiet for a moderately A/T truck tire. They do need to be fully inflated for even tread wear going by the truck manufacturer's recommened front and rear pressure specs and not using the tire manufacturer's load capacity table.
I replaced them with Nitto Terra Grappler 285/70R17 tires and found that in addition to the 3750 load capacity they provided a firmer ride with better handling with a full load in the bed on the corners. Oddly enough with a full load on the rear axle the new tires with the load were the same height as the stock tires without a load so my speedometer and odometer were more acccurate with the new tires when traveling.
