Cant really say that i could give good advice on the tires,for all around use,but i just installed 27" Mud Machines,Tri Claw,Bi Claw combo,on my 2005 grizzly...It is awsome in mud and for riding in cut downs,but will stick you fast in sand..I really like the tires, so i think i will put some good sand tires on the factory rims..I dont go in much sand, but will change them over when i go to the beach...Anyway, these are a very aggressive mud tread,and like i say, they will pull good across cut downs..I am kinda new to the atv scene,just thought ya might wanna look at these...I realize just because i bought them ,dont mean they are the best,lol..I just like them so far!!

 

I have ITP 589 on my brute anf they work great. Here is a link for tire weight tooTire weights
