Yup, I had my 34"s calibrated better than the OEM calibration with factory tires.Give it a shot and see what happens v. GPS. The factory speedo is typically conservative by 1 mph indicated to mitigate claims of "my speedo is wrong and I got a ticket". Just about every vehicle I've owned indicates ever-so-slightly faster speed. Confirm it's recording mileage properly by driving a calculated route via mapping software.
