Why does a new car show low tire pressure?
4 Answers
Mainly because the car has been parked for too long. Specific reasons and solutions for low tire pressure: The tire pressure decreases when the car has been parked for too long; manufacturers intentionally lower the tire pressure to prevent high-speed driving; tire damage; any of these issues require inspection and repair at a 4S shop or auto repair shop. High tire pressure: If the car's tire pressure is too high, driving comfort will decrease, leading to more bumps, susceptibility to external impacts, and increased wear. If the tire pressure is too low, it can cause uneven wear and increase the wear area. It is essential to use tires correctly. Improper use can lead to tire damage, increased fuel consumption, and in severe cases, tire blowouts, which pose a safety hazard. Original tires or parts are relatively better, so try to protect them. Pay attention to road conditions while driving to avoid punctures, and slow down when encountering speed bumps or uneven roads. When parking, try to park in the shade, as exposure to sunlight can reduce the tire's lifespan.
Low tire pressure warnings in new cars are quite common, often due to imprecise factory settings or minor leaks during transport and storage. I've encountered this alert several times with new vehicles, especially when temperatures drop. Cold weather affects gas expansion, so slightly lower pressure is normal, but persistent warnings require inspection. First, use a tire gauge to check all four tires—standard pressures are listed on the door placard. If all are low, simply refill at a gas station. If one tire is significantly lower, it might indicate a puncture or valve leak. New car sensors sometimes give false alarms before full system calibration; driving 30-50 km may resolve it. Ignoring this accelerates tire wear and increases fuel consumption, so prioritize tire checks during the first service. Don’t panic—just test and address it promptly.
I feel a bit annoyed when I see the low tire pressure display on my new car, probably because the tires are still in the break-in period or the sensors aren't calibrated properly. Tire pressure can fluctuate before the new car is delivered, such as during the temperature changes from the factory to the dealership. I checked common causes on my phone app, and the TPMS system might give false alarms, especially during initialization right after startup. I tried measuring the actual pressure myself—just buy a digital tire pressure gauge; they're very cheap. Low pressure can increase tire noise and make steering less responsive, affecting safe driving. With a new car, I always worry about punctures, so I carefully inspect the tread to avoid hidden issues. I recommend driving to a nearby service station to inflate the tires and clarify the warranty coverage for the new car. This way, small problems can be resolved quickly.
The low tire pressure warning on my new car makes me uneasy, possibly due to suboptimal factory settings or transportation oversight. I've learned that pressure drops with temperature are normal, but persistent alerts warrant inspection. Manual pressure checks can be done with tools available at gas stations. Incorrect pressure increases blowout risks, especially at high speeds. For my new vehicle, I prioritize complimentary dealer inspections to prevent tire imbalance. Safety first—don't delay addressing this.
