I have a bone stock '93 explorer sport 4x4, would like to put 31x10.50 mud terrains on it but not sure if they will fit, stock tire size is a 235/75r15.....or should I jus go with some 30x9.50's, I dont wanna have any issues with rubbing when the suspension is flexed or when steering, what do u guys suggest, want something wider and little taller than stock
