Thanks everyone. This set is questionable, but the other two are just outright bald, bald, bald and needed to be replaced. The set in the pictures look a little more worn in real life than they do in the photo. You can see noticeable cracks, although the tread is fairly good. It looks like an old, dried up rubber band. I don't feel great about them. But the front two had to go. They were bad. I didn't feel good about them or safe.
From what you guys have said, there are a few things I can do. I'd like to get the extra inch lift, so I might just wait till next month and have them all put on at once, which is basically two weeks away. Thank you all. The help has really been so great. I haven't owned a car in a long time. I had a 76 Bug many years ago, and I've never had a truck or a 4x4. I'm really glad I do now, I've always wanted one.
