熱胎之後的胎壓只會稍微上升,就算跑長途也頂多是個位數字的變化 (大多是5左右,不會超過10)不可能出現"多少倍"的情況除非你的"多少倍"指的是小數點部分,例如:36psi上升到40psi = 增加11% = 1.11倍
Air Pressure, Temperature FluctuationsThe rule of thumb is for every 10° Fahrenheit change in air temperature, your tire's inflation pressure will change by about 1 psi (up with higher temperatures and down with lower).
