I am absolutely convinced that folks are going to be amazed by how well the G.O.A.T modes work in conjunction with open diffs.
A year or so from now, we may be sitting back in amazement watching videos of a Base Bronco (perhaps with a mild aftermarket lift and some 33s) following a Sasquatch...
The rabid first year buyers will buy a Bronco regardless of these perceived limitations. A certain number of frustrated folks will wait and, magically, Ford will address some of the issues for MY22, then a few more for MY23 and so on....to keep the public interested and bolster sales. As was...
The Ranger Base offers this 18" wheel upgrade "standalone" for $999 (from 16", so different tires as well). Ford could certainly offer some sort of wheel/tire option on the Base Bronco if they wanted to.....but their approach is to create pain points to try and force buyers to one of...
The Ranger Base trim offers these as a standalone upgrade option for $999. They're 18", so not desirable (to me) as a Base Bronco upgrade....but it is a good example of what Ford could do if they wanted to.
There would be some obvious fitment issues with "just" a tire/wheel substitution (i.e., I'm pretty sure the Sas 35s won't fit properly without the associated suspension lift). That being said, I would love to see a standalone 265/75-16 all-terrain option on the Base.
I look forward to the day when we know specifically which suspension components (other than the coil-overs) are different between Sasquatch/Badlands and the other trim levels.
The rotational inertia is affected more by tire weight, than by weight of the wheel. Tire distributors typically list tire weights....not sure about the comparative weight of the wheels, but I bet it isn't as much as you think. While alloy is less dense, it also tends to be a lot thicker.
