275/40s will be great in the back. If you have a 9" front, a 255/40 would be good, but a 245/40 will fit and look ok. For an 8" front, a 245/40 will look best IMO

 

On Foxes I would go with 17x9s in the rear wearing 275/40/17s...the fronts I would go with 17x8s wearing 245/45/17s...

Another option would be to go with 17x8s all around with 245/45/17s on all four...

Due to the differences in these cars,some might need a little BFH treatment on the inner wheel wells but usually nothing outrageous.Also wether you drop her or not can make a difference and might need you to also do some lip rolling...You never really know until you get in there with the combo you want...Theres always a way!!!!
