For clarity, a "Reinforced" or "Extra Load" 
passenger-car tire appears to fall between 
passenger-car load ranges B and C.  As the load 
range increases, so does the inflation pressure 
for max load rating -- for standard (LR B) tires 
it's 35 psi, for RF or XL tires it's 42 psi, for 
LR C tires I believe it's 50 psi.

Sources -- various, including Falken tire, Kumho 
tire, Continental tire, and  US FMCVSS �571.139 
Standard No. 139; New pneumatic radial tires for light vehicles.
