Why does my tire pressure say psi?
Why does my tire pressure say psi?
The acronym P.S.I. stands for Pounds per Square Inch. Generally speaking, it is the unit of measure inside a chamber containing gas. In the case of car tires, its the amount of pressure air exerts when inside of the tire.
Why does my TPMS light say low tire pressure?
So check your tires carefully. If your vehicle has a TPMS, it’s probably monitoring the pressure in your spare tire. Therefore, if you get a low tire pressure warning light, and if you’ve checked all four tires that are touching the ground, than you might need to put some air in the spare. Recommended tire pressure can be very confusing.
What should the pressure be on a SL tire?
The maximum allowed pressure listed on a tire’s sidewall can be higher however. Some tires list 44 psi and many higher speed tires will list 50-51 psi. This added pressure does nothing for load capacity. Pressures above 35-36 psi for SL tires and 41-42 psi for XL tires will not increase the load capacity of the tire.
What’s the lowest tire pressure you can drive with?
If you have standard passenger tires (ninety percent of vehicles do) the lowest tire pressure you can generally drive with is 20 pounds per square inch (PSI). Anything under 20 PSI is considered a flat tire, and puts you at risk for a potentially devastating blowout. How low does tire pressure have to be for the low tire pressure light to come on?
What’s the best way to reset a low tire pressure light?
Probably the easiest method is to drive about 10 miles at 50 mph. Use the cruise control to keep the speed constant. Some vehicles reset the sensors at higher speeds than others. Shut off the car.

What to do if your TPMS warning light is still on?
If you’ve checked all your tires (including the spare) and the tire warning light is still illuminated, reset your tire pressure monitoring systems. Some models require the TPMS to be reset every time pressure is added. Instructions for how to reset your tire warning light vary from model to model.
Where is the tire pressure light located on a car?
As discussed earlier, the TPMS is located on the rim of the tire. Thus, there are chances that this electronic box gets damage during the tire change process. So, whenever you are going for a car’s tire change, do check the pressure light there and then.
