I maintain that the Right Rear Inner is the most abused of the six tires. Like its left inner partner, it bears a little more than its share of the load because the crown of the road gives the outers a little break.
I'm not quite sure about that, the crown of a 2 lane road runs from the centerline to the shoulder in a single run. In a divided (Interstate type highway) the slope is a single run from side to side.
There is never an instance where the crown is designed to be in the center of a vehicle.
Jaxdad didn't say that the road lane is crowned in its middle- I took his point to be that the (continuous) slope from the crown being high-to-low, it shifts weight from the crownside wheels to the shoulderside wheels. Might not be a LOT of weight, but I agree that it may be enough to make a difference over time.
