Should both front tires be inflated to the same number if they have different loads? Tires on the same axle should be inflated to the pressure required by the largest load
Driver's front is 2007 lbs, Passenger's is 1720 lbs.
Does ride improve as pressure is lowered? Yes it will to a certain extent but you should never go below the pressure required to support the load
Should the rear duals all be inflated to the same pressure?Same answer here. The duals should be inflated to the pressure required to support the max load and both duals should be the same pressure
Driver's rear is 5534 lbs, Passenger's is 5181
