I am running the Interco Interforce and absolutely love them! I have 30's. I bought 30x8 for the front and 30x10 for the rear using stock wheels. $479 delivered to my door from Chapparal Racing and they were here in 3 days from order. I did a slight mod to the frame up front and completely removed the rear sway bar. I posted some pics of the frame mod. Took about an hour to do and looks great. Any good welder could do it for you if you dont weld. I got a much better ride than stock, insane good ground clearance and a much better traction. These tires are wearing incredibly well. Good...they bite and grab like you wont believe, the 500 almost seemed perfectly geared for these tires. 4wd is needed much less with these tires and it will climb like a goat. Bad...they obviously vastly increase height and I'm using the stock wheels to stay inside 50 inches to avoid issues with forest service natzis. While I love the huge ground clearance gains, I could see where it could get "tippy" in the most extreme conditions. Also I notice on pavement a hum/vibration at speed because of the massive tread. We generally drive slow and I avoid pavement for various reasons. Wife doesnt appreciate me driving on our lawn as every turn takes chunks from the lawn. We have been riding in steep, rocky trails at over 7000ft elevation and I love the tires. I was at a huge ATV rally over the 4'th and I had the only Pioneer 500. Numerous RZR guys were checking out my ride and at least 1 was pissed that he had just paid $21K for his 50 inch and he clearly had 5 inches less ground clearance and was crunched down in his seat like a sardine packed in the can. I dont think 30's are for everyone and if you are wanting to run the dirt roads as fast as you can run, sliding and drifting in to corners, dont buy this tire or any 30 inch tire for that matter. We like to trail ride at normal speeds and these tires in my opinion are a HUGE improvement over stock. p.s the "coolness" factor is off the meter. Definitely gets other riders attention!
