New to site, new to quads!

Newby here from the beautiful hills of Tennessee, just picked up my first quad (never actually even sat on one untill last week!) a 2000 Grizzly 600 with 1,500 miles (it was cheap).
Been "exterminating" wild hogs on the farm and finally figured out that a quad would make dragging them out of the woods (and up-hill) a lot easier!

I do have a question, the machine has aftermarket chrome wheels and oversized tires (ITP Blackwater XTs in 27×10-12 & 27×12-12) that have some wear on the fronts (rears look new). Since I won’t be mudding and the hills are steep and wooded, would I be better off to replace the tires with the original 25s with a less mud grip tread?

Looking forward to making some trails in the woods!
