I know that the SL is not as tough as the C laod ratting would be (see below for what each are. My concern though is that I dont need the higher load rating because my off-roading needs arent quite has high as others, but was wondering if there was still justification to get one over the other. BTW the C rated tires are $26 more a tire (or 130 more for 5 shipped).
Load C:
Load Range Ply Rating Load Pressure (psi)
C 6 50
Load SL:
Standard Load P-metric tires will have nothing branded on their sidewalls or may be branded as "Standard Load," while Extra Load P-metric tires will be branded as "Extra Load," and identified by an "XL" in their descriptions, as in P235/75R-15 XL
