I think you'd need to make a number of changes to ensure no rubbing on the outside edges under high load.
I went outside just now and put the Telly up on one ramp in the back, to get compression on two opposite corners. The ramp isn't quite tall enough to drive compression to the point of touching, but this is providing some good data. Here are some photos, and explanation of what I'm seeing.

Looking at the driver side rear. I put a tape measure in on top of the wheel and placed the end of it right at the point in the wheel well where the inner plastic starts to ramp up the ~2" extra clearance. Looking straight down from above (sorry the photo doesn't do a good job of this), there is almost 1" to the outside edge of the tire. So, in order to tuck into the wheel well the outside edge of the rear tire needs to be 1" inboard:

Moving up front to the passenger side front. The methodology was the same - find the inner wheel well recessed point, measure from there out to the outside edge of the tire. Up front the tires stick outboard by a little more than 1 1/4" inches. The photo does not do the measurement justice, since I didn't the photo straight above. But the measurement showed that the outside edge of the tire would need to be 1 1/4" to 1 1/2" inboard in order to tuck under and in to the wheel well recessed section.

I then cranked the steering wheel hard over and took a look at the gap between the inside tire wall and the strut. In here there is about 1 1/4" of gap, so could comfortable go Inboard 1" with the tire wall. It doesn't appear it would rub anywhere doing this, but hard to say if perhaps on full lock the opposite direction it might up front.
So, in terms of your question about being able to fit by going down to 55 height, no, this alone won't get them to fit in the wheel well entirely. I think you'd need to reduce the width as well. Another option is the 2" truxx lift, which others have done and like. (I'm considering it).
