? on getting 17 front and 18 rear
If you put a 17x9.5 up front, you'd wanna put a 275-40-17 tire. The overall diameter of which would be 25.66". If you put a 18x9.5 in the back, youd want a 275-35-18 tire. That diameter would be about 25.58. You wont start upsetting ABS or TCS until you get to about a 1/2" difference.
Nevertheless, IMO, staggered diameter rims DO NOT belong on an f-body. The wheels wells werent designed for that like a vette.

If you had a 17x9 rim up front, a 275-40-17 tire would be appropriate.
If you had a 18x10 rim in back, a 295-35-18 would be the best choice of tire size. A 305-35-18 will be a little larger and thus more likely to upset ABS and TCS. I myself have 295-35-18s out back with stock diameter tires up front and I have no problems.
