How does extreme cold affect tire pressure, and what should you do about it?
- A.Pressure drops as air contracts in the cold, so check pressure with a gauge when tires are cold and inflate to the recommended level
- B.Pressure rises sharply in cold weather
- C.Cold tires never need checking
- D.Overinflate by 20 psi to compensate
Correct answer
A. Pressure drops as air contracts in the cold, so check pressure with a gauge when tires are cold and inflate to the recommended level
Why
Tire pressure falls roughly with temperature, and an underinflated tire flexes, overheats internally, and handles poorly even in winter. A gauge check matters because a tire can be significantly low before it looks flat.
