Home / Low Tire Pressure Warning Light
Whether you use a tire pressure gauge or your vehicle’s internal tire pressure monitoring system (TPMS), this is the time of year you’ll see your low tire pressure sensor come on your dashboard. Don’t worry – it’s very normal. However, do not put off in fixing what your vehicle is telling you needs attention.
We see it every year in the fall when air temperatures begin to drop. Customers come into our shop and tell us: “My low tire pressure indicator light is on.” While these are a great feature to have in your car, truck or SUV, they can get annoying.
You may (or may not) know that as air becomes warm, it expands. As air cools, in contracts. So use that lesson in thinking about your vehicle’s tires and the air they hold. Your tire pressure monitoring systems tell you: “Hey! We’re low on air. So, you better fill us back up to our normal pressure!” This may happen when there is only a 4-5 PSI (pounds per square inch) drop in tire pressure. While your vehicle may have operated with correct tire pressures all summer, the air constricts in cooler temperatures and so your vehicle tells you that its tire(s) could be low on air. Hence, the low tire pressure light illuminates on your dashboard.
How can you correct this? There are several ways to correct this and they’re really simple:
The first use of nitrogen was in aircraft tires, which are constantly exposed to extreme temperature fluctuations. Some people think nitrogen is flammable or explosive. However, it is not and can be found in about 70% of Earth’s atmosphere.
So the question is: Why should I put nitrogen in my tires?
Unlike regular air, nitrogen does not expand and contract with a change in temperatures. Therefore, from Summer to Fall, the air in tires constrict and trigger the low tire pressure lights on your vehicle. With nitrogen, this should almost never happen simply because it is a very stable gas.
Consider replacing your tires’ air with nitrogen at Creech Import Repair. Not only will you have a more stable tire pressure, but you’ll gain peace-of-mind knowing that your tire pressures will remain constant throughout the year instead of having to deal with fluctuations.
