2006 rzr wheels & tires ???

I am considering purchasing a set of steel wheels and tires from a 2006 rzr, the are new take offs with zero miles.
I want to use these on my 2001 sportsman 400, the fronts are the same tire size, the rears are different. So I am not sure if they will fit yet or not.?
Does anyone remember how the factory tires preformed, where the acceptable or where they junk????

Thanks in advance….
