Yup, with 73+ spindles and rotors a 17x8” about 5.5”-5.7” of backspace would be ideal for a 245 or even 255. That’s the maximum backspace, right around 5.7” of backspace is where the outer tie rod end clearance becomes an issue.
With a Barracuda the 255 would require the lower fender corner mod as the profile availble in 255 makes the wheel 26” tall. The 245 is more like 25.6” so that works without the mod with the maximum backspace
