I'm certainly no stranger to heavily modified cars. That 78 TransAm in my avatar originally had a 6.6L with 3 speed automatic. I then dropped in a 2001 LS1 with 6 speed manual, and it now has a 2013 LS3 with 6 speed and a Z06 clutch. Plus nearly every piece of the suspension, steering and braking has been completely changed, and the wheels are nowhere near the stock size. It's basically nothing like the original, except in appearance.
However all of that is basically mechanical. It can all be drawn out and/or calculated. There's no real mystery there. (yes, I know the engine itself is heavily based on electronics, but that's not really the same as what we're discussing)
With the '14 jeep, so many of the basic systems are based on computer algorithms and are basically "black box". Programming is my profession and as they say: "garbage in, garbage out". You give it the wrong data and it's going to give you the wrong answer. And without any visibility into the algorithms, I have no idea how to evaluate whether a 5% error is negligible or significant. My guess is it's more toward the negligible side, but I'm not sure I'm willing to bet on that right now. It also doesn't address whether or not there is an impact on warranty service.
Now if we (or the dealers) had a way of setting the tire size so that the computer was making the right calculations, I'd feel a whole lot better. And it seems like there must be a way to do this, especially if the TrailHawk-II does end up getting released with the 35" tires it was demoed with.
But anyway, I probably shouldn't derail this thread any longer since the original topic was simply trying to get people to contact Cooper and ask them for more sizes.
