I've already tested my truck with the 37s off road so far no issues just had the shop check it out after the first 500 miles after lift ended up being more about 800 miles. Shop said no rubbing issues and no problems that they could see. They guarantee there work so if it rubs and messes up the tire they will replace it. I already some how got a scratch on one of my new wheels. The shop said they would order a replacement and take care of everything.
