Hello group. New guy here. Looking to buy a new 4 cylinder FWD Equinox and I noticed two deferent axle ratios. Is this due to tire size? Does one perform better than the other. Does one give better gas mileage? I realize if all things are equal, a lower ratio will give better mileage and a higher number will change the performance. Just checking to see if the tire size compensates for the two ratios.
