由于胎压与胎皮使用循环数息息相关，针对能否提高现行胎压标准，与波音做了较多的沟通。最终波音的解释如下：
一是胎压变化影响轮胎与地面接触面，与设计的刹车距离会有差异；
二是轮舱内爆胎的取证压力问题，对其他管路、线路等的影响。基于以上初始适航取证问题，不可以进行随意调整。
因而与轮胎本身额定设计压力会存在一些区别。
Even though Ref /A/ reference guide lists a MLG tire pressure higher than what is required in Ref /B/, Boeing notes that 737-800 is certified to operate only at MLG tire pressures specified in Ref /B/.
Increasing the tire pressure above allowable limits changes the tire footprint on the ground which directly affects its certified stopping distance. In addition, the airplane wheel well components (cables, pipes, brackets, etc.) were all certified to withstand potential tire burst event at maximum pressure as listed in Ref /B/. Operating MLG tire pressures higher than values specified in Ref /B/ would be deviating from allowable airplane certification limitations and are therefore not authorized.
