Question: what are load range on tires?
Answer: Load Range Is Based on 'Ply Rating' A tire's 'Load Range' can be found on the tire's sidewall represented by a letter, usually after the tire size (35X12. 50 R17/E for example). This code represents the ability of the tire to hold air and weight; the higher the load range (A→G) the heavier load the tire can carry.
