Tire Inflation Pressure Limits
What I meant by what I said is that you stay within the maximum pressure capacity of your tire. Lower profile tires tend to have a higher max pressure (44psi as opposed to 35psi). As such 40 psi would not be over-inflating for the 225's, but would be for the 195's. (Though in reality due to safety factors the tire COULD potentially run between 20-50% more air than what is listed; I do not recommend this)
