The purpose of the TPMS (Tire Pressure Monitoring System) is to alert you when tire pressure is too low and could create unsafe driving conditions. If the light is illuminated, it means your tires could be underinflated, which can lead to undue tire wear and possible tire failure.

Why is my tire pressure light on when my tires are fine?
There are times when the low tire pressure light will turn ON even if the tires are fine. Your best recourse is to manually check the pressure of each tire to confirm the problem. After this, you can simply reset the TPMS to get rid of the low tire pressure warning light on the dash.
When should you worry about tire pressure?
A TPMS warns the driver when tires are low on air, but this warning isn't issued until a tire's air pressure is 25 percent below the automaker's recommended pounds per square inch. That amount of underinflation is severe.
How low is tire pressure when light comes on?
Since the tires' optimal performance and safety benefits are realized within a specific range of air pressure, measured in pounds per square inch (psi), the warning light may illuminate when pressure has dropped as little as 10 percent below the recommendation—long before low pressure is visible to the eye.
Why won't my low tire pressure light go off?
If you've inflated your tires to the proper air pressure, but the warning light stays on, you may have a leak or there's a problem with the TPMS in one or more of your tires. It's simple enough to check if there's a leak in a tire. Just use your tire gauge to recheck the air pressure in all your tires.
Can you take a driving test with the tire pressure light on?
Can I take my driver's license test with the TPMS light on? ... Just inform your drive test examiner of that fact. First thing they will do is to “eyeball” your tire. If they see that your tire is not low on air, there is a very high chance they will believe that is the case and give you a pass on the light.
Is it safe to drive with tire pressure sensor fault?
No, driving with the TPMS Light on is not safe. It means one of your tires is underinflated or overinflated. ... This can cause undue wear on the tire, potentially lead to a tire failure, and cause a blowout dangerous to you and other drivers on the road.
Why do dealers overinflate tires?
Did you check the pressure after driving the car while tires were warm or did you check pressure first thing in morning when tires are cold? Tires are overinflated during the shipping process, so as to help prevent the flat spot from forming in the tire as it sits for days on in during the shipping process.
At what PSI will a tire explode?
To cause a car tire to pop, you would likely have to over-inflated the tire by 200 psi or more. This is why car manufacturers don't even list the number it would take to pop a tire.
Is 30 psi enough for tires?
Being low on pressure doesn't hurt the tire or the wheel at all, unless they get very low, like 10 PSI. Also, you should check your owner's manual to see what the correct tire pressure setting is. 30 PSI is a safe bet, although the odds of your car specifying exactly 30 are rare.
Should you put air in your tires when it's cold?
Yes, you typically need to inflate your tires in cold weather. As we'll explain, low temperatures often mean low tire pressure, and low tire pressure could mean dangerous driving.
Is 40 psi good tire pressure?
1. What's The Recommended Tire Pressure For My Car? ... Normal tire pressure is usually between 32~40 psi(pounds per square inch) when they are cold. So make sure you check your tire pressure after a long stay and usually, you can do it in the early morning.
