I ended up purchasing the 15x8 with 4.5 backspace for rear and 15x7 with 4 backspacing for front, I figured that it’ll be a safe combo with room for error and can easily be solved with some spacers if needed. I think tonight I’m gonna order the 255/60/15 for the rear and the 215/60/15 for the front. I’m not making Over 450 wheel so I don’t think that a 255 will feel much different from a 275 and I think it’ll look just as good. As I said earlier If there’s still too much tuck in the rear I’ll just buy a couple spacers and call it a day:)
