Tire/Wheel Question

I have 27x9x12 and 27x11x12 mud tires currently on my 07 700 with 1 inch spacers. I am buying new tires as these are worn out. If I get ITP Delta Steel wheel with 4+3 offset will I still need my spacers. I would like to not use them. Thanks
Here is what I am getting:
Blackwater Evolution
27x9x12
27x11x12
ITP delta steel wheels
12×7 w 4+3 offset
