How do you determine what is the optimum tire pressure for best fuel efficiency?

Carbonbased Lifeform questioned:
Do you just go by the pressure manifest on the tires and pump up the tire to that pressure?

The tire pressure plotted on the tires is a maximum. DO NOT fill with air to that pressure. The optimum tire pressure for your car is on a sticker on the drivers side door sill. That is the pressure to fill your tires to.
Empirical normal.

To enlarge on the previous answers:
The pressure manifest on the tire is the maximum pressure which the tire is capable of effective at. By huge the tire to this pressure, you enlarge it such that the bottom of the tire (the go up touching the road) bulges. This earnings that you have less area touching the ground, and you will have less footing.
Your vehicle must have a manual that states what the optimum tire pressure is. The wits that the manual can quote an optimum pressure for a diversity of tire types (all time of year, chill, summer, etc) is in view of the fact that the consequence of the car does not chat very much, and therefore the total amount of break down to keep the car tires with the maximum go up area on the road doesn’t chat very much. (The domestic pressure break down of the tires, distributed on four wheels, equals the consequence of the car.)
Summation: Read the owner’s manual for your vehicle and it must give you the optimum tire pressure. This is always the pressure you want to fill with air your tires to.
The optimum pressure for the best fuel efficiency is the maximum pressure the tire can survive. The privileged the pressure the less friction.
The pressure elected by the automobile manufacturer and tire manufacturer is a negotiate to take up fuel efficiency and the comfort for the passengers.
Stick with the not compulsory pressure in your owners manual and you stand a better opportunity of not having a chow down and a possible loss of hegemony and really terrible accident.
How you handbook, that is, how you accelerate, brake and the speed you travel at has a much larger impression on mpg than just raising your tire pressure.
