Re: Larger Tires, 2014 GC, Overland Diesel, QL2
I also have the QLII and I have no rubbing at all even at park height. I have 275/65/18's on mine which equals a total tire size of 32.07 inches (814.7mm). Your 275/55/20's would be a total size of 31.91 inches (810.5mm) which are slighty smaller. You should be fine with those, I would be surprised if they rub.
