[i][b]昨天去给车子打了一下气，检查了一下轮胎的压力。
我这个小轿车，标称的标准轮胎压力是29PSI，我多打了一点点，在打气之前，把pump上的气压设定为31PSI，然后在对四个轮胎都加压至31PSI。今天开车，感觉车开起来轻松很多，比较爽的那种感觉。
注意两点：[ul]
- 轮胎加压之后，要更加注意刹车距离。因为同样的反应时间下，刹车距离会变长一些。
- 急转弯的地方，速度一定要更加降低一点，防止轮胎变形爆胎。

请开车有经验的朋友点评一下我这个做法。

理论上来说冬天不是应该低一些，夏天高一些吗？
我个人一直以来的习惯就是，冬天里，轮胎气压稍稍加大一点点。不过还是小心为好。下面的资料是比较权威的。
Tyre pressure
Tyre PressureCorrect tyre pressure can help to extend the life of your tyre, improve vehicle safety and maintain fuel efficiency. Pressure is measured by calculating the amount of air that has been pumped into the inner lining of your tyre in pounds force(PSI) or BAR pressure.
The manufacturer of your vehicle specifies the suitable pressure, and it is your responsibility to make sure that the pressure is checked and corrected on a regular basis, at least every couple of weeks.
Maintaining correct Tyre Pressures
There are three main reasons why maintaining the right tyre pressure is important. The first is safety. Tyres that are under inflated can overheat; and over inflated tyres can lead to poor vehicle handling on the road.
The second reason is economy. Over or under inflated tyres suffer more damage than those with the correct pressure and need to be replaced more regularly. Vehicles with under-inflated tyres have increased rolling resistance that require more fuel to maintain the same speed.
The third reason for maintaining the correct tyre pressure is the environment. Correct tyre pressures help to maintain optimum fuel efficiency. This can equate to lower Co2 emissions coming from your vehicle than those with incorrect tyre pressures and that has to be good for the environment.

It’s important to check tyre pressure regularly. It’s not always apparent that air is being lost, but it generally escapes at the rate of up to two pounds of air every month. More air is usually lost during warm weather, so more regular checks are needed when temperatures rise.
Look for the tyre pressure recommended for your vehicle in your vehicle hand book or within the technical information usually found on the inside of your vehicle’s front right hand door or fuel tank flap.
Always check the tyre pressure with a tyre pressure gauge when your tyres are cold. Finally, if you are using your vehicle to carry additional load or weight, always consult your vehicle handbook for the correct loaded tyre pressure.

不同的车型和轮胎
不同的气压吧
前胎和后胎也不同
外行
等看行家的意见
理论上是这么回事：
冬天温度低，所以轮胎里的气体体积会收缩，造成实际压力降低；夏天则反之。
理论是：Gas Law。
对，不同的车是不同的。
楼猪，你真是个女汉纸！这种事情不直接扔给男人去干就好了。。
每年一次的mot
加上定期遵丛车场的建议换新胎
应该就能cover 轮胎气压这个问题
我是外行所以从来不操心轮胎的事
呵呵，我是人见人爱的女孩子，不是女汉子。
记得苹果上几个男生很懂车
他们的说法比较可靠
冬天路滑，气压不用太高，容易打滑
有道理，合了我第二点注意事项，弯道更加降低速度减速。
lz的大字报让我想起大学时代的某某考研
您这样还真不行，这意味着你的车每年可能只有一次MOT的机会检查胎压（换胎更是要好几年一次了），但是最好还是养成习惯，每过几天就目测一下，有没有明显瘪了的论坛，然后每几个月（已经很懒了），加油的时候用打气机再检查一下。
不懂这方面的
外行
轮胎的气压多打没事，可以增加点儿mpg，但是打太多会造成轮胎中心磨损比边缘快
我标准33，都打到38的
在英国东南这种不怎么下雪的地方，冬天多点儿也没什么问题
小车也应该是32左右。低于30不太对。
你车里有气压读数的吗？
Standard for my car: 29
胎压每个车不同，有些车前后轮也不同。像BMW还把载一人还是四人分开两种胎压。总之按照车门贴纸打气就行了
汽车跟自行车一样，轮胎没气阻力就大，轮胎气多阻力小省油但是会磨损边缘导致寿命简短。个人认为没啥好取舍的这个厂家已经找到最优解给你了为啥不用。加气刻意多加少加的都是小聪明。根据贴纸加就对了
还有一般一个月肯定要检查一次。胎压表几磅钱一个不用省。买一个吧
PS：现在只有sainsbury 加气是免费的
求推荐：轮胎气压表和汽车轮胎打气筒。
