My rims are 14”. And do plan on getting a clutch kit eventually but I need tires right now. I seen and read people putting 10” wide on front. I know the rims are 11” rear and 7” front. I’m just want the most ground clearance with the 2” lift. Do a lot of rock climbing and constantly dragging the belly and a-arms.I would not run the same size tire on all four corners on "stock" rims. Mainly because the fronts are not as wide as the back. Also, many stock wheels were just 12 inches in diameter. As for running a 30 inch tire on a Teryx with a 2" lift, I have heard many people say they can but with minor rubbing at full lock. Some remove or modify the front floorboard shields to gain extra clearance. And one last note, wheel spacers can actually make the rubbing situation worse at full lock.
I run the 28x10x14 Rockabilly on my bike with 2" lift and am very happy with this tire. I have over 2000 miles on my current set and have never had a problem.
You didn't mention anything about your clutch, but if you are going to run over-sized tires, you are likely going to want a clutch kit.
