    Hello!

    Is there anyway to get the speedometre to read correctly after changing the diameter or the wheel?
    It gets thrown off and I was wondering if I did go ahead and buy the wheels can I make it give me correct speed and mileage.

    The car in question is a 1998 Skoda Felicia, after the VW facelift, so it has all VW parts.

    Thanks.

    The wheel size (diameter) WILL alter the ROLLING CIRCUMFERENCE of the wheel. Therefore when you go up on the diameter of the wheel you will have to go down on the aspect ratio of the tyre. This will then compensate for the change. Your wheel and tyre supplier would know which size you require.
