Also, just more to think about.

If that lift has been on there for a long time the actual mileage could be greater than the odometer shows. The larger tires have a larger diameter and thus travel further with each rotation. Unless it was regeared (which I doubt) the actual mileage could be up to 25% higher (based off a factory 31? tire versus a 37? tire in regards to the difference in circumference). That would mean the actual mileage would be over 250,000.
