need some tire recommendations

2014 outlander800xt running the stock xt tires now which are pretty good but they took a beating. I ride in northern Pa in the mountains,coal region and there is allot of rocks I hit after two trail rides the lugs have chunks taking out of them from rocks. Looking for another set of tires ones that can withstand the beating of Rocky trails but can give me a pretty smooth ride and can dig down in the mud when I need them too. Thanks in advance
