Subject: In a four-wheel-drive car which tire will get thinner?

Sir
 This is my last question - In the mid engine car the center of gravity is in 
center then which tire will get thinner the front or the rear ?

You Said:
 "Whichever tire is providing the force to move
the vehicle:  front tire in a front-drive car,
rear tire in a rear-drive car."

Suppose in the four-wheel-drive car: which tire will get thinner the rear or the 
front (Which will wear faster?)?
