I see that on our Compasses, the rear wheel is not centered in the wheel well.

Why is that? Not that I was going to go with a larger tire, but it limits the diameter without lifting.

Nobody knows for sure but possibly as simple as something they elected not to fix after copy-and-pasting the basic design of the Fiat 500 / Renegade to use as the starting point for this car. Somebody in design apparently did more stretching than the engineers were able to keep up with. Maybe became an issue of desired track width vs wheelbase length, like another inch would have somehow negatively affected the handling or rollover resistance. Its annoying, for sure. Maybe someday there will be a differential relocation kit available in aftermarket, but I wouldn't hold my breath. Two wheel drive versions could probably move it very easily but nobody buying a two wheel drive jeep likely gives a hoot anyways.

Look at the angle of the rear strut, it's not straight vertical, it's rearward. As the strut compresses the wheel moves up and back in the wheel well. It's by design.

Yeah its this. It is a design element added to make the ride more comfortable. When you go over a bump, rather than the wheel going straight up and pushing the car up, the wheel can move in accordance with the motions of the car and give a much smoother motion. It is also the same reason why if you go over a bump in reverse, it is very rough (as this desing limits the motion of strut in reverse direction).

So if the wheel was centered with the design, the tire would hit the rear of the wheel wall. In a sense they need that much of space between the wheel.

I good question is why didnt they made larger space for the rear wheel so that it can be centered and this suspension system still works. I assume the reason is the size of the car. On a car that is relatively small like this, you cant make a very large wheel space. If they made the front of the wheel wall as wide as the rear, it would take a lot of space from the rear doors and would probably make the car look strange (since front and rear would be different sized). It might also cause other issues like wind noise and a drop in MPG due to drag. Other options were to change the wheel base (which is expensive since they need to modify the chassis).

Aesthetics as you mentioned different wheel arches and occupying interior space.

All four of my wheels are perfectly centered in all four wheel wells. Want to know why? It is because I ordered Mopar splash guards at the time I purchased my Compass new. Everyone who complains about this did not get splash guards. The Compass looks much better with them, so just order a set to correct this.
