what is 省位备胎?

GRMVT

就是比实际轮胎要小的备用轮胎，一般日本进口车都是采用这样的备胎，好处是成本低，环保，占用空间小，汽车在事故后比较容易更换， 容易辨认，提醒临时使用备胎者及时更换会正常轮胎。

不利的是不能如正常轮胎般使用，更不能长途使用。

Space-saver wheels

Some cars have a space-saver wheel as the spare wheel. Space-saver wheels are much smaller than the vehicle's other wheels so they take up less storage room.

Space-saver wheels are for emergency use only and are not designed to be used over long distances. If you get a flat tyre and replace a wheel with a space-saver wheel, you should only use it to get directly home or to a place where the flat tyre can be repaired or replaced.

The vehicle is likely to handle differently with a space-saver wheel. Drive carefully and don't drive faster than 80km/h. If the space-saver wheel has a sticker showing a lower speed, then that speed applies.

Space-saver wheels must have a safety label that states that the tyre is for temporary use only, what the maximum safe speed is for the tyre and what the correct pressure is. Make sure you read and follow the label.

Note: make sure the space-saver tyre is inflated to the correct pressure. This is much higher than normal tyre pressure.

一般来说，最高速度不超过80KM/H在使用这备胎的时候。
