f******d 发帖数: 6361 | 1 我的车子是toyota camry,我最近发现(以前没有很留意)前胎看上去明显比后胎flat。
厂商recommend的最大胎压是35pound。无论是自己打气还是mechanic给我打气,我都是
要求32-33pound。作天我换engineer oil,还做了tyre rotation,mechanic说给我打
了32pound。我今早发现前胎仍然明显比后胎flat。我google了一下,这好像是正常
的,但还是想请教一下大家。
网上看到的解释:
1.
That's a characteristic of radial tires cars today have radial tuned suspension and there is a curvature in the sidewall that helps the car respond to curvy roads , swerving around an obstacle to avoid crash.etc. and the slight bend in the steel belts give the illusion of a tire being under inflated
2.
they look flat because that is the way radials these days are made. it is just a more flexible durable material. absolutely normal。 |

了吧。5-10K做一次比较好。

比车尾重不少。

setting. What is in owner's manual? If it states 32psi, which is under
assumption that car is cold. It the car is driven for more than 1 mile, it
is considered to be "warm/hot". In this case you need to raise the tire
pressure at least additional 4+ psi.
For better gas mileage, it's also suggested to raise the tire pressure a
little bit. In addition, the #1 reason of blow-out is low tire pressure. I
usually set the tire pressure to 38psi, which should have enough safe margin
as the tire allows max of 44 psi.

f******d 发帖数: 6361 | 7 不是吧?厂商建议的最大胎压是35pound,我所去过的mechanic也只推荐33pound左右,
不过我住的地方都是全美最热的。

b****n 发帖数: 3343 | 8 Which 厂商 are you referring to? Tire manufacturer? If 35psi is what is
marked on the tire, you should not exceed that. My tire allows max of 44 psi so I set it at 38psi to leave enough safe margin while providing better gas mileage and blow-out protection.
I thought you were referring to car manufacturer's recommendation when you talked about 厂商建议.
