So far the only issue I really ran into with the larger tires was the belt slipping (and axles breaking), which were both an issue even before that in the rocks. I will say now that I installed the Duraclutch, although I have not put a ton of miles on it yet, I did have a chance to do a bit of crawling with it and can say the thing is amazing. The combination of the 30" tires (beadlocks and airdowned to 6-8psi) and that Duraclutch is amazing. It really is like a caterpillar. I definitely don't have any complaints as of yet. I may have mentioned it before but we have a big trip coming up in a couple of weeks where we will do quite a bit of rock crawling and I will definitely have more to report back then on the setup. My main interests/concerns are going to be with the drivetrain. That being said, having the duraclutch allows me to control the power so much more as I can literally crawl it and control it so I think it should go well. I did purchase a front Rhino axle for a spare though lol, which Rhino's will probably end up all being the primary's when it's all said and done. As far as the power goes, I still have plenty to go around. I honestly didn't feel like I had larger tires going from the stock to the 30's. It was really quite impressive. I ran the pi$$ out of it on a motocross track (which is what screwed up one of the first front axles) with the bigger tires on it and it jumped and powered through it great!Welcome to the forum. I've managed to dodge the rzr bullet, but not by much. Very nearly ended up with a 570 or new 900. All your problems were my concerns. I wanted bigger tires but after talking to a buddy and him suggesting to stick with the stock size due to gearing and weight I understood. If you reclutch you're just going to lose out elsewhere in the powerband. I'm planning to run the tires off this thing and replace them with growlers or rockers of the same size.
