Yes, I calibrated my UG against my GPS. When the odometer shows 100 miles traveled, I've actually traveled 109.9 miles - a significant difference.
The OEM tires/wheels weighed 36 lbs each: 17 for the steelies, and 19 for the tires. The run-flats weighed 48 lbs: 22 for the wheels, and 26 for the tires. I haven't put the new wheels/tires on the scale, but they should weigh in @ 44 lbs for the combo.
