Slime in tires

I’ve always have put slime in my ATV tires and in my bobcat tires and even in my zero turn mower tires but have noticed no posts about slime in rzr tires ??, but have read about what’s needed on the trail when a tire goes flat ?? ( spare tire- plug kit- patch kit- air compressor)
I just got a good price on 2 gals of slime should I slime my tires now or wait for a flat
