Just had our new mojave at silver lake last weekend, that is exactly what it was made for, the suspension is awesome. We have a 2010 jku with a aev lift and much prefer the mojave
Cummins did a study, under 50mph tires hace the biggest effects on mpg, over 50 mph it is aerodynamics. Whilwe they were talking about trucks I guess it applies to everything. We drive a brick with big tires.
