On my 2 wheel drive vehicles, or part time 4wd I never rotate the tires (how do you know you have a problem if you are applying the problem to multiple tires so they all wear down equally). On full time 4wd I do rotate about every 8-10K after checking them carefully for abnormal wear.
All of my two wheel drive vehicles in the last 30 years have worn down tires perfectly. No weird or accelerated tire wear. If there is weird or accelerated tire wear get it fixed by an excellent alignment shop and I cannot stress that enough. In San Diego, back in the day when I worked in a garage, there were only two shops that we knew of that did outstanding alignment work. There were many hundreds of other shops that were on some level bad to horrible. The tire shops were the worst! We had an alignment rack, but didn't do alignments because it is a science that very few people can get right every time. Many shops make your problem worse. I have stories, but I'll just leave it at that.
