I stated all of the tire sizes for myself and the OP.
The 17s were either 45 series or 50 series. Both sizes were tested. The 15s are a 65 series. Revs/mile were also listed.
RPM is too difficult to monitor because of the power split device and how it regulates RPM.
Speedometer and odometer effects were monitored, however.
