What pressure should my 4×4 tyres be?
Do you check tyre pressure hot or cold?
You should always check your tyre pressure when the tyres are cold — i.e. before you’ve made any journeys that day. This is because warm or hot tyres that have recently been driven on may give inaccurate pressure readings.
What is the best time to check tire pressure?
first thing in the morning
Edmunds states you should check the pressure when the tires are cold, as the friction from driving causes them to heat up and affects the pressure. Check them first thing in the morning or, if you’re already driven the car, Consumer Reports recommends waiting at least three hours for the tires to cool down.
How long should tires sit before checking pressure?
three hours
Answer: The rule of thumb is that you need to wait three hours with the car parked before the tires are cool enough to get an accurate pressure reading. In addition, you should try not to drive more than one mile in getting to a pump if you want to recheck the pressure when you add air.
Should I check my tire pressure hot or cold?
