Short of trying a set of tires, I think it will be hard to figure it out. It will be close. I was just looking for reassurance.
I don’t think it will pinch low on the plastic cladding like the taller 215/55/16 does, but I think there is a chance that it will hit higher on the fender when the wheel is turned during cornering. I just can’t quite figure it out for sure, even though I have been measuring and measuring and measuring.
My car is 1 inch lower at all 4 corners. Depending on the wheel, it is 25.25 inches to 25.5 inches at the fender lip.
I don’t remember the stock offset, although I can just check my stock “Special Edition” wheels that are stacked in my garage to find out. I think they might have been ET44 and they are 15 inches x 6.5 inches.
Below is a view of the front of my car that shows how far the tires are tucked under my front fenders and a side view that will give you an idea about the drop.

I think it might be like always going back to that same bad relationship with an ex girlfriend.
You feel you love them too much, or you are just too stupid to know any better.
