Full set of Maxxis BigHorn Radial 26x9-12 and 26x12-12 ATV Tires (4)

Will these fit a 2011 polaris rzr 800s

Are theses the original bighorn? These are not 2.0 bighorn right? They do come with the while lettering on the side wall correct?

I have a 2019 grizzly with 26x8/12 in front and 26x10/12 in rear. Will these fit the wheels properly?

Are these redial tires? The listing doesn't have the R in front of diameter like it should for radials.
