The air pressure in your spare tire should be the same as...?

The lowest pressure tire on your vehicle
The average pressure of the tires on your vehicle
The highest pressure tire on your vehicle
A standard pressure recommended by the manufacturer

The correct answer is: The highest pressure tire on your vehicle

The air pressure in your spare tire should be the same as the highest pressure tire on your vehicle. This is because the spare tire is typically used as a replacement for a flat or damaged tire, therefore it should be able to support the same amount of weight and have the same level of inflation as the tire it is replacing. Option A is incorrect because the lowest pressure tire on your vehicle may be under-inflated and not provide enough support for the spare tire. Option B is incorrect because taking the average pressure of all the tires may not accurately reflect the pressure needed for a specific tire. Option D may also be incorrect because the manufacturer's recommended standard pressure may not take into account the weight and inflation needed for a specific tire on your vehicle. Therefore, the best option is to match the spare tire pressure to the highest pressure tire on your vehicle.
