What got me thinking about these topics is that a friend of mine is considering selling his XJ. It is a 1998 SE model. The odometer reads 106k, and it has had 33" tires since 65k, and 30-31" before that. I have estimated that the actual distance traveled is closer to ~121k. With that said, the majority of the drivetrain has only rotated 106k worth of times.
What I am trying to figure out is the overall wear and tear on the vehicle. There are many things that affect this including the total amount of time the vehicle has been operated, total distance traveled in relation to rotations of the drivetrain, and stress applied to the various parts of the vehicle. For example, I would think that total time operated would have more of an effect on the engine than distance traveled; the vehicle can be at be at rest while the engine runs. Operation time is consistent across odometer readings though, meaning it shouldn't take you longer to get to your desination on 33s than it would on stock tires. With that said, this vehicle would still have 121k worth of operating time on it.
What about the rest of the drivetrain though? The axle shafts, etc have only made 106k worth of rotations, and I would think that the wear and tear on those parts would be less related to time operated and more related to distance traveled (rotations). It does take more force to rotate 33" tires in comparison to stock though, which could be translated into more stress on the drivetrain. So I guess the question is, does the added stress from larger tires cancel out the fact that there are less rotations of the drivetrain? Should i accept that the my friends truck has 121k, or should I think it has 106k and a longer engine operating time?
