There are many myths and misconceptions about tire pressure detection, which can lead drivers to make mistakes that affect their safety and their vehicle’s performance. Let’s debunk some of the most common myths to help you keep your tires in top condition.
Myth 1: You only need to check your tire pressure when the TPMS light comes on.
Fact: The TPMS light is designed to alert you when your tire pressure is significantly low—usually 25% below the recommended level. By the time the light comes on, your tires are already underinflated, which can affect handling and increase the risk of a blowout. You should check your tire pressure manually at least once a month, and before long road trips.
Myth 2: The pressure listed on the tire is the recommended pressure.
Fact: The pressure listed on the tire is the maximum pressure the tire can handle, not the ideal pressure for your vehicle. The recommended pressure for your vehicle is found on a sticker inside the driver’s door jamb, in the glove box, or in the owner’s manual. Using the maximum pressure can lead to overinflated tires, which reduce traction and increase the risk of a blowout.
Myth 3: You don’t need to check your spare tire’s pressure.
Fact: Many drivers forget to check their spare tire’s pressure, but a flat spare tire is useless in an emergency. Spare tires can lose pressure over time, even if they’re not used. Check your spare tire’s pressure at least once every six months, and follow the recommended pressure listed on the tire or in your owner’s manual.
Myth 4: Underinflated tires are only a problem in cold weather.
Fact: While cold weather can cause tire pressure to drop, underinflated tires are a problem all year round. In hot weather, underinflated tires can overheat and blow out more easily. They also reduce fuel efficiency and cause uneven tire wear, no matter the season.
Myth 5: You can’t overinflate your tires if you use the recommended pressure.
Fact: Even if you use the recommended pressure, you can still overinflate your tires if you check them when they’re hot. Driving heats up tires, which increases pressure temporarily. Always check your tire pressure when the tires are cold (meaning you haven’t driven more than a mile or two in the past three hours) to get an accurate reading. If you check your tires when they’re hot, you might accidentally add too much air, leading to overinflation.
By debunking these myths, you can make more informed decisions about tire pressure detection and keep your vehicle safe and efficient on the road.
