XL means Extra Load range which indicates the tire has a higher Load Index and Maximum Inflation Pressure (usually 51 psi instead of 44 psi) than a Standard Load range tire of the same size.
Standard load P-metric will not show a load range but rather a load index like a passenger tire. Extra load P-Metric will be identified with an XL, as in P235/75R15XL. Light truck (LT) and flotation tires have their load range listed with a letter, as in LT235/85R16/E or 31x10.50R15/C.
