Standard passenger (P) tires MUST have their load capacity devalued by about 10% when used on trailer axles.
Light Truck (LT) tires maintain their load capacity when used on trailer axles. However, they are already rated much lower in load capacity when compared to a like sized Special Trailer (ST) tire. Here is an example…. LT235/85R16E has a maximum load capacity of 3042# at 80 psi….ST235/85R16E has a maximum load capacity of 3640# at 80 psi.
