Highlifter tires or??

I have the stock Highlifter 2015 tires on my buggy, after spending plenty of forum surfing. I see that most have taken off those stock tires and have gone with other tires. WHY??? I like how they look, but I’m older and will never have that thing in that type of mud, I’m a family rider and would like to stay a little cleaner. So do different tires help keep the inside cleaner?? And what type of new tire did you go with? And is there anyone who left those on?? Thanks
