Tire pressure changes as the temperature. If the tire pressure is insufficient, it may cause tire punctured. Under normal circumstances, pneumatic tire without enough air blowout risk is higher. If the tires lose air continuing driving, which will deform the tire sidewall, driving for a long time, will accumulate a lot of heat inside the tire, and the heat will eventually lead to changes in air pressure inside the tire, causing a puncture.

Even before the start of the long-distance driving, to conduct a comprehensive inspection of the tire, the tire pressure is due to environmental factors change. Moreover, many luxury car tire pressure monitoring alarm is by tire speed monitoring, the principle is that when a tire pressure abnormality occurs, the speed is different from other tires. This vehicle with the same tire pressure monitoring alarm also has a big risk.
