06 4WD Ranger wheel and tire fitment

Yeah, the '11 got 16's as an option to "modernize" it, even though it was considered a legacy chassis by then. They didn't change gearing, just ran lower profile tires to stay close. Apparently the speedometer accuracy is just a general guideline and not an end goal. I have learned a lot about that kind of stuff lately.

Rabbit holes...

Most manufacturers set their vehicles up so the speedometer reads about 2 -3 mph faster than you are really going. They say it helps reduce the chances of getting a ticket for speeding.

I think it's more for giving them more flexibility in tire sizes for different trim packages. The later Rangers came with 29", 30", and 31" actual size or metric size equivalent tires.

I forget what the inch size is for the 225/70R15 tires on the RWD Rangers is. Probably 28"

You wanna really have some fun. Look up specs of the actual tire you're considering running. There are quite few cases of being an inch smaller than advertised on the sidewall.

I remember one (Kenda maybe) listing for a 30x9.5R15 being exactly the same dimension under the same air pressure as the 235/75R15 at 28.9in.
