Hi Jerry, You might want to have your tachometer recalibrate. At 65 MPH you should be turning about 2500 RPM. Do the math. 5.13 rear end gear, 32" diameter tires, .71 OD ratio. Or if you have a 5.38 gear, then you should be turning about 2600 RPM. You might have to slow down a bit to drive at your 2200 RPM torque peak.
16" IS NOT the "rolling radius" of a 32" tall tire!!!
