轮胎方面的请教

[ps3]

请问原配轮胎大小是225/50 17的轮胎，能不能用225/45 17得胎呢？ （轮箍大小一样，都是17*8。5 的）

好像是在车门打开之后的门边还是哪儿写有各种可用SIZE的.

可能可以用，如果不擦到frame，但是速度会比实际快

周长变了

周长变了

原配轮胎直径是 225mm * 50% *2 + 17inch, 225/45 17的直径是225mm * 45% *2 + 17inch. 所以周长变短了. 同样转速下, 速度会略慢. 里程表的读数会偏大. 同时对刹车系统, ABS 等的影响也会略有变化.

Technically, NO.

那为什么可以用245/40 18的轮胎呀？

It is not recommended, but certainly can use.

As several posters have indicated, the diameter is changed. Therefore, the speedo meter and distance will not be accurate any more.

As far as ABS, it sense either the differential, or the mouting of the wheel (behind brake disc). Therefore, it is a wrong assumption that with 5% different, the ABS will malfunction.

See Howstuffworks "The ABS System" for ABS operation
