When I bought the Griz, I had the dealer throw some wicked looking EFX MotoMTC tires on it.
EFX MotoMTC – All Terrain ATV Tire and UTV Tire by EFX Performance

I noticed the other day that sometimes my quad seems a little unpredictable while ascending a tree rooted or rocky hill. Kind of grabs and hops around some. It yanked the front end around pretty violently a couple times.

Too much tire? Or just me not being experienced enough?

I don’t ride deep mud. Just trail riding with light mud.
I am thinking of something else, like maybe ITP Terracrosses.
