After thinking about this larger tire -- better MPG thing, I have the following ideas/questions....
Too many posters say larger tires cause worse MPG
Smaller tires put down more torque to the road.
Since the axle rotates faster with smaller tires, it's like higher gears, right?
Going to larger tires is like having less gear.
Less gear may make it harder to propel the HEAVY VX from a stop.
Larger tires creates less rpm on the hwy but requires more to launch.
Maybe larger tires raise MPG if primarily driven on the hwy?
Maybe larger tires lower MPG if doing a lot of stop-go driving?
Maybe larger-tire-owners should activate the "POWER" setting so the transmission stays in lower/higher gears longer.
By running in POWER mode, they'd gain back some of the leverage/torque of the smaller wheels.
Just some random thoughts.
