Tires, Reinforced, Extra Load
Tires with XL designation have a higher load rating than tires without this designation.
Some time ago, the designation "Reinforced" was replaced with the designation "Extra Load" by some tire manufacturers. In countries outside Europe, this designation has been conventional for some time. There are no technical differences.
Some tire manufacturers also use the "XL" designation for Extra Load tires.
Tires with the designations "Reinforced" or "Extra Load (XL)" are the same.
