Dumpling:
Quick calculation on spacing between wheels with tires mounted. I run 275/40/17 fronts and 315/35/17 rears both of which have a posted diameter or 25.7". Given a 90" wheel base that puts the distance between the back of the front tire and front of the back tire at 64.3".
On paper, it should clear but that's purely theoretical. Still waiting on more information from the manufacturer.
