Not if using your stock wheels. The spacer (rear only) is to account for offset if using matching offset aftermarket wheels along with the new tires to account for track width differences. Some guys run them, some don't.Okay, this might be a dumb question, but if I upgrade to 30x10-15 on front/rear of my 21 1000R live valve, will I need to use a spacer?
