Just bought a set of 27" 589's for my stepsons rhino. I put 27-11 12's all the way around and have a pretty smooth ride. You get a little bounce at around 3 to 5 mph but after that it is nice and smooth. They seem to turn much easier than the original stock tires, I guess this is from having contact more in the center of the tire than the whole width of the stock tire.
