Stock tires and Hatfield McCoy

We are planning a trip to HMT.
Both quads have stock Polaris tires (Carlile PXT). These tires appear to be more agressive but they say they are all terrain. Am I off base?
Looking for a better tire for both.
The 1000 is also used as a yard hauler. The 850 is all play.
Do not want to break the bank and want to keep stock rims.

Let the opinions fly!
