I've bought Super Swampers twice, and I haven't been impressed with how long they last. Then again, it all depends on what you are planning to do. I go off road occasionally, so most of my driving is done on the road. I imagine most people are in the same boat. In 6 months I noticed that my tires were worn quite a bit. I had to replace them in less than two years, and that was with a 6 month cross rotating. So I went with a more highway friendly tire that has some tread for off road usage, and I'm pleased. They were much cheaper too.
