An E rated tire at 65 psi attains a load range rating equal to a D rated tire. Check out the chart I linked above.
And therefore, your "D" load tire (E rated inflated to 65 psi is a D rated tire) will comfortably carry your 7600 lbs. I went with "D" rated Maxxis knowing that the max pressure allowed by the wheels was 65 psi. I saw very little benefit in putting on E rated tires if I could only inflate them to 65ps. My biggest gain and increase in peace of mind came from taking off the factory C rated tires and installing the Maxxis D rated.
