Hmmm. 245/45-16 would be a pretty fat tire on the skinny 16" rims! You'd have some serious balloons there. Don't know if they'd even seat a bead on the factory rims, would they?
I borrowed the wheel/tire from a friend - perhaps I'll try them on again in the spring and do a test drive to see how they handle, but they poke out waaay to much the way it is now. These were 17x8" rims, but I think if I'd ever try a low offset like the Justice's had, I'd opt for a 225/45-17 to get closer to plus one sizing.
