Why do tires get deflated easily when fall and winter come in? You can understand the reaction of tire pressure whenever there are changes in external temperature by reading more of this infographic. There are cases when the owner of car wonders why the car which was inflated with the right amount of pressure during nighttime loses its pressure in just one night. That is simply because, during night time, the temperature drops much. The lower the temperature, the lower the tire pressure could be.
1. Pressure is measured in psi. This pressure is measured through how inflated the tire is. You can feel that the tire gets tighter. So what if there is enough pressure in the tire? For those who have driven the cars for a long time, they can definitely tell the difference between well-inflated tires versus those that have lower air pressure index. This is important because safety and control are well associated with tire’s psi.
2. You might already know how gas particles react to hot temperatures. These particles move in different directions causing the tire to get inflated. However, when the temperature is low, these particles slow down and does not go upward causing the pressure to get lower.
3. Generally, when the temperature drops by ten degrees, it will result in a drop in the air pressure index by 1 or 2. However, when you drive it going somewhere, the tires will be warmed up and will heat up the gas particles hence increasing the tire pressure. For every 5 minutes within the first 20 minutes of driving, you get an additional 1 psi.
4. PSI is used by Tire Manufacturers to indicate the air pressure needed. However, such number is set when the car is in its cool conditions. Normally, you would measure air pressure at home. But, you might not have the machine to inflate your tires, you will need to drive in a repair shop or gasoline stations. Hence, it will readily affect the tire pressures. It is suggested that you record the psi at your home and then add up the pressure you need.
5. Do not disregard underinflated tires because it can cause accidents. For one, tires that do not have the right amount of air pressure will be hard to control, decrease the car’s efficiency and increase friction. On the other hand, if the tire’s pressure is too high, the ride could be bumpier.
6. You cannot predict what may happen on the road. Sometimes, even if you have driving skills, other drivers may not have the best driving practices. Hence, control of your own wheels is very necessary. You must develop a habit of checking your tire pressure before leaving your home or office. You also need to be sensitive with your tire conditions. If you feel that something is wrong, you must not ignore it. Instead, follow your gut feeling because drivers develop such 6th sense about their cars. If you don’t have such intuition yet, visit a tire repair shop from time to time.
