Just put these front tires on my Polaris Sportsman 500. I had them mounted on my stock rims and was nervous about them rubbing tie rod/struts. THEY FIT PERFECTLY! They makes a BIG difference over stock tires in the mud. I also put 25-12-12s on the rear. Again, they fit perfectly. My machine is bone stock. The added width and tread depth make a huge difference in the tuff stuff. Yet they are still a 25 inch tire and only slightly heavier than stock, so no noticeable loss in power. IMHO a real good tire choice for mid size machines........Haydo from MA.
