My ground control plates are awesome, they make a pretty big difference. I'm running 255/40/17 on a 17x9 et 45 fronts are about a finger or less gap rears are ever so slightly tucked. little rub under heavy suspension loading on the rear fender and needed 3mm spacers on the front to keep them from touching the strut. probably would have been fine but just in case i run them. 245/40/17s would fit easy.
