Will the 4.7 final drive ratio kill MPG and TOP end speed for use as practical daily driver?

[Ronaldo]

The tire diameters makes up for the ratio mostly And with that ten speed I’m sure it will be close. That being said the 4.7s on the Sasquatch with high drag mud tires is going to hurt your mileage a bit. The fastest bronco may be a big bend with 255/75/17 tires, 4.45 locker, V6 EcoBoost, and ten speed auto. 4 wheel drive launch! After that tune it.

Would it be over simplifying to say, keep 4.46 if you plan to use 33s, or, upgrade to 4.7 if you want 35s?

What if you plan on 285/75/17? That's where I'm gonna live and I failed many math and science classes
