I have a 98 Yamaha Big Bear 350 4x4, and it currently has the stock style tires on it right now, but I'm wanting to go with an aggressive tire with a lot of bite in and out of the mud. Also I was thinking about going a size up from my 25x10x12 in the rear and 25x8x12 in the front, what tires would you guys suggest for this application??

 

i suggest mudlites.... or mudsharks.. those r the 2 tires of choice around here.. also 489 and 589s r good tires.. put 589s on the rear and 489s on the front..

 

itp 589's or mud lite xtr's if you could turn'em.
