Demon rear tire/wheel combo question??

He isn't asking about 18" wheels he is asking about 15" wheels.

Thank you, definitely not an 18" wheel guy..

Doesn’t matter. Look at the section widths and do the math. Yes, you’ll need more clearance with the tall tires and 15” rims because of the flexibility of the sidewalls, but I addressed that in my post. You’ll have the extra room because those tires are smaller than mine.

The point was, and is, that I have wider tires on my car at a lower ride height than what you were asking about, and yes, you can fit 10” wide rims on there if you want to do the 1/2” spring offset and are willing to do a little trimming on the quarter lip. With the higher ride height and smaller tires you should have the clearance you need.
