The important calculation that was ignored was the load capacity for the two rear tires. With a drive axle total load of 6900 lbs. that works out to 3450 lb. per tire. I would bet that your factory tires are rated at 3195@80 PSI and so you are most likely overloaded where it counts the most. Overloaded tires are going to have more sidewall flex and run hotter and are much more likely to fail catastrophically - i.e. a blowout.
They're rated for 3,500 lbs each. Don't see a need to upgrade at this point.
The Transforece LT 275/70 R18 is rated at 3640 lbs per tirerack.
Curious if the OEM version is different than that.
