what is the largest diameter of tire that i can fit
 

Hi, i own a 2010 F150 xl double cab. and i dont really want to get involve into change or lift it but i do want to by a set of bf goodrich mud terrain II for it.

The question i have is withouth changing a thing of my truck what would be the largest diameter i can make fit on to it without haveing the risk of damage the truck. i tried some 305 i think but they say i was going to hit the front wheels everytime i turn.

my rims are 17" and they are ok, i just want to fill the rest of the space with tire.

I dont have to many experience and i have no way to know how the tire look because i have to pay the wheels before they can mount it on the truck.

thank you all
