I've been trying to weed through all of the lift/tire threads to see which tires will be best for me. I just had a 2" lift installed last week and i'm looking for a little taller tires. From what i've read if I get the 255/70 I will need wheel spacers to keep from scrubbing, is that correct? I would rather just get the 245/70s if I have to get spacers. Are my assumptions correct? Thanks in advance.
