What does 'outside' mean on tires?
2 Answers
In cars, 'outside' refers to the external temperature. Here is a detailed explanation of the external temperature: 1. When a car displays 'outside' followed by a number, it generally indicates the current external temperature. When the outdoor temperature is below 4 degrees, it alerts you that the external environment is cold, and there may be icy roads, reminding the driver to pay attention to driving safety and avoid sudden braking to prevent danger. 2. 'Outside' in a car refers to the external temperature, reminding that the outdoor temperature is lower than the interior temperature, and suggesting the driver to turn on the heater to prevent window fogging. 3. The external temperature sensor, also known as the ambient temperature sensor, is usually installed near the front bumper or grille. Its sensing element uses a negative temperature coefficient thermistor. The detection method for the external temperature sensor is the same as that for the coolant temperature sensor, and its resistance can be measured with a multimeter in resistance mode—the lower the temperature, the higher the resistance.
I remember when I used to drive a small truck and changed a tire, I noticed the word 'Outside' on the sidewall. That indicates the side should face outward toward the road, while the inner side would have 'Inside' marking the wheel's inner side. If you accidentally install it backward, like I did once during a hasty winter tire change, the car would make a constant roaring noise, as if the bearing was damaged. Later, when I took it to the repair shop, they found it was a tire issue. After reinstalling it correctly, the noise disappeared. Otherwise, uneven tire wear could affect braking. I recommend regularly checking your tires, including tire pressure and tread wear indicators. These small details can save you big trouble, especially when driving on highways in rainy conditions to maintain proper drainage design. Don’t end up like me, wasting money on repairs and time.
