酷热天气下轮胎气压会升高。如果轮胎很热,您应该:
英文原文: In very hot weather the tire air pressure rises. If the tires are hot, you should:
- 放气直到气压正常
- 补气以平衡热量
- 开快一点来降温
- 不要放气 (not let air out of the tires)
答案: D. 气压随温度升高,所以不要放气,否则轮胎冷却后气压会过低。
来源: North Dakota CDL Manual (AAMVA model), Section 2, p. 53Do not let air out or the pressure will be too low when the tires cool off.
