Only put wheels 18" and larger on a a Ranger if you're bagging it. Otherwise it'll just look like a stupid donk. If you're static dropping it, go with 18s with a 35 profile on a 4/5 drop and you'll sit nice without looking stupid. Make sure to get some wider tires too, like a 225/35/18, so they dont look like pizza cutters.
Those rims you want are super gay btw. May as well just stick some tinfoil pie plates on your existing rims for the same effect.
