    OK so I got a new to me car a few weeks ago, one of the reasons I bought it was to save fuel, tax and money on tyres when it comes to changing them

    Went from a Freelander to a Seat Exeo Sport 2.0 TDi

    Anyways... tyres.... was checking prices on the tyres which are on the car at the moment which are 225/45 R17 however when entering my reg plate into black circles it suggests I should be using 220/45 R18

    I know what the numbers are, I just don't understand what they actually mean in the real world.

    Should I be using the recommended size ones? Should I stick with what I have? What's the advantages and disadvantages of both?

    Thanks,
    Keith

    220 seems a strange width. Just stick with 225 as its only 5 mm width and will fit no probs. Most people think the 45 is the profile in mm, its actually a % of the width.

    Stick with the current size or they won't fit the wheels correctly.
    If you changed the tyre size you would have to change the wheels to match.

    A sticker somewhere on the car should tell you the tyre pressures relative to the car wheel size.

    I'd stick with OE spec to avoid any handling issues and insurance company get out excuses.
