What exactly is Rod force......when tyres r balanced the rod force on the tyres r checkes and placed (FL,FR,RL,RR) accordingly based on their rod force....isnt it??
Sorry, I'm afraid you're going to have to rephrase that. I don't really have a clue what you are trying to ask.

Could you possibly refering to tie rod force? This is the force required to overcome the centrifugal (some say centripidal) or gyroscopic force to change the tire's direction of travel. The lighter the tire (less mass), the less force required. You can do the same thing with a gyroscope and see the result when you try to change the direction of travel.
