Question: what is the difference between e1 and e2 tires?
Answer: Load INDEX is equally important in determining weight capacity as load RANGE. For instance, a load range E, load index 121 tire at 50 psi can carry 2470lbs, whereas a load range E2, load index 121 tire at 50 psi can handle 2755lbs. However, either tire at max pressure, 80 psi and 65 psi respectively, can carry 3195lbs.
