Typically, a driver should receive this warning when the pressure is 25% below than the recommended level. Once the message is received, you are required to check the pressure in all the tyres using pressure gauge and inflate the tyres to the required pressure if any one of them is found deflated.
How do I reset the TYRE pressure warning light on Mercedes?
With the vehicle off, turn the key to the “ON” position without actually starting the car. Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait 20 minutes so the sensor can refresh.
The first place to look for the correct air pressure for your specific tires is your vehicle owner’s manual. Correct air pressure should also be listed on the tire placard attached to the vehicle door edge, doorpost, glove box door or fuel door.

Is 40 PSI too high for tires?
Specifically, the level of 40 psi can be suitable for passenger cars or sports cars. But this is too high for small cars with a recommendation below 35 psi, while 40 psi is too low for large trucks. The recommended level for the tires of famous sports cars and passenger cars is between 32 -40 psi.
Should all 4 tires have the same PSI?
It is not true that all 4 of your car’s tires should have the same tire pressure. However, all the tires you buy for the same vehicle will require the same tire pressure, regardless of the tire manufacturer – the PSI specified in the car’s owner’s manual.
How do you adjust tire pressure at a gas station?
Should tires be filled to max PSI?
Your tires’ max PSI almost always exceeds the recommended pressure. It isn’t advisable to fill your tire to this pressure for everyday driving. At max PSI, your car does not handle as well, braking is impaired, and you could risk dangerous blowouts.
What tire pressure is too high?
Here are some ideas to know if the tire pressure is too high for your vehicle: Small cars should not reach more than 35 PSI. Passenger cars and sports cars can have tire pressure not more than 40 PSI. Large trucks can reach more than 40 PSI.
For instance, if 35 psi is recommended, and the maximum safe pressure listed on your sidewall is 44 psi, you can safely put 38 or 40 psi in your tires. You can even go to 44 psi. You’ll experience a harder ride, but you won’t create a blowout danger. You may even experience sharper cornering and increased fuel economy.
Is it bad to slightly over inflate your tires?
Tires will wear out prematurely. Overinflated tires round out on the tread section and cause the center to wear down significantly faster than the outer edges. This could cause them to last only half as long as they typically would. Overinflation can cause loss of traction.
Why do car dealers over inflate tires?
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. It is supposed to be part of the delivery check process that the service department deflates the tires to the proper pressure.
What happens if I over inflate my tires?
Most seriously, overinflated tires are at greater risk for a blowout. A tire blowout can cause you to lose control of your vehicle and negatively affect braking distance, endangering yourself and others on the road.
How do I know if my tire has too much air?
4 Symptoms Of Over-Inflated Tires
Lack Of Traction. The first sign that your tires are over-inflated is a loss of traction.
The tire should be inflated to near the limit of the tire. That is, if the limit on the tire is 44 PSI then you should get it up to 42 or 43 PSI. The recommended tire pressure on the driver’s door (usually around 30 PSI) should be ignored.
Is 49 too high for tire pressure?
In most of these cases, 40 psi should be more than enough, and since most modern tire designs will allow up to 44 psi (in some cases more) this is not a problem. If you have a heavily loaded vehicle, up to 44 or even higher is ok if the tire allows it, but this is a little high for most vehicles.
Is 45 psi too high for tires?
Is it OK? It is technically “ok”, but I would deflate the air to 35 psi. Reason being is it will ride rougher with more air in the tires, and it will wear the tread much faster. It will give you a little bit better gas mileage, but not to the point where it will break you even on tires.
Why does my tire say 50 psi?
Fifty psi is a lot of pressure for a passenger-car tire. That number is on the sidewall because it’s the tire’s maximum allowable pressure. That means you can put up to 50 pounds of air in that tire without worrying about the tire exploding or deforming to the point where the car won’t handle safely.
What does 44 psi mean on a tire?
Tire pressure is typically determined by vehicle weight and type of tire. In other words, the 44 psi you refer to is the maximum inflation of the the tire at its maximum load rating. You can safely inflate the tires to the maximum pressure, but it may not give you the best ride or performance.
Is 50 psi too high?
Press. 340 kPa ( 50 PSI)”. This means that the tire will safely carry up to 1477 lbs. and can be safely inflated up to 300 kPa (Kilopascal) or 50 psi (pounds per square inch).
