Why would tire pressure light come on after getting new tires?
Each tire’s pressure sensor is housed in the valve stem. A few minutes after you start up the car, each one communicates, wirelessly, with the car’s computer. If the pressure is low, the computer makes the dashboard light go on. Or, if one of the sensors does not communicate at all, that also makes the light go on.
Do new tires have pressure sensors?
Tire Pressure Monitoring Sensors or TPMS is a relatively new technology on the vehicle market, however nowadays most vehicles will come with one.
What to do when your tire sensor is off?
While the sensor is off of the rim, it is standard procedure to rebuild each sensor and replace the grommets on the rim. Then you mount the tire normally. After that, you push the top bead down, reinsert the sensor unit, and tighten the nut on the sensor unit to the specified torque.
Why do you need a tire pressure sensor?
The system works and is one way to catch under inflation situations that are the cause of many tire failures. The tire pressure sensor represents a safety feature that is worth while having. Not everyone is going to go the cheap way out and then have the discipline to check tire pressure on a regular basis.
Why is my tire light not working after replacing a tire?
What happens is that when the tire tech is dismounting the beads of the tires, occasionally the lip of the tool used to remove the tire will strike the sensor and damage it. The sensors are not cheap. And anytime you replace a sensor, you must register the sensor with the vehicle. Otherwise the TPMS system will not function properly.
Can a low pressure tire light be replaced?
The TPMS doesn’t have an effect on the operation of the car other than turning on the “low pressure” light. So that $74 sensor can be replaced with a $5 pressure gauge, a piece of electrical tape over the light, and a few minutes every couple weeks to check the pressure. TPMS is a handy system, but its too expensive for what it does, in my opinion.
Can a tire sensor be damaged during a tire change?
A sensor can be damaged during: Normal tire service; Tire replacement; Brake system work; Tire rotation; A CV boot/axle replacement; An oil change; A filter change; Additionally, the air pressure gauge may be miscalibrated, or the battery that powers the sensor may have died. In these cases, the sensor will need to be recalibrated or replaced.
When do you reset the tire pressure sensor?
They monitor the speed of the rotations of the wheels for any change since underinflated tires are smaller and rotate faster. Though they do not affect tire balance nor corrode, they must be reset with a scanning tool whenever tires are replaced or rotated. Determine the type of TPMS system.
How does the tire pressure sensor work on a car?
Each tire pressure system monitors the tire pressure within each of the tires and alerts the driver of low tire pressure (25 percent or more below or above recommended inflation pressure); however, the two systems monitor that pressure in two different ways.

When does the low tire pressure light turn off?
The low tire pressure light, also know as the TPMS system, on your car should turn off when you have filled your tires to the proper pressure, or “PSI.” Sometimes, it just doesn’t work though.
