今天就把你的16寸小胎换成19寸大胎吧。一点点投入，车子的milage可以增加20%。
里程表还走的慢，将来能卖好价钱 |

the wheel to turn at same RPM, your engine have to run harder, burning more
fuel.
The best efficiency is reached when the wheel's rotation speed combined with
gear ratio falls within the engine's optimal operating RPM range. Simply
changing the wheel to a bigger size generally result in lower fuel
efficiency. |

相应赚得多。 |
