I love mine. 
I have the 33x13.50x15 Rocker. I wish it was a little taller.
Wheeling with them is awesome. The truck goes where I point it. On road is so-so. At 70, it sounds like you're riding in an airplane, and they shake the truck a bit, but it's all tolerable. I understand that they are a bias off road tire, not a high performance road tire.
I've had no issues with them, other than bead problems. The last wheeling trip i aired down to 7 psi, without beadlocks. I got dirt in one bead and had to break it down and clean it to hold air. Then I completely lost a bead coming down a hill. The sidewalls are a bit stiff, so that probably contributed to the bead issues. I ran 10 psi the rest of the weekend and they held just fine.
Here's a good idea of cost: http://www.4wheelerssupply.com/catalog/index.php/cPath/468_516?osCsid=0915c320f03a27d429be45ec5de14a56. Or you could call up Mike Green at Pit Bull directly. He's an awesome guy! 
What is the width of your wheel? Could that be contributing to the bead loss? I was advised to stay away from them by our local toyota guru..he said they suck on road, chunk and are not the right compound for MO wheeling...dont have any personal experience with the tires though
