Hi! I have a 2014 Rex with 5" front and 5.5" rear wheels. I'm planning to install Ecopia 175/55R20 in the front and S001 195/50R20 in the rear.

I've been reading a lot of consuming information, but wanted to understand if I can do this setup without any spacers, or are they mandatory? I understand they help improve stability, but I'm not sure if I've got the budget to spare at this moment.
