    Default tyre size effect on speedo reading...

    Hi folks

    I've been reading on here about putting 225/45/17 tyres on as a cheaper replacement for the 215/50/17 on my vec.

    I have a question about that.... I know that the difference in the tyre height profile is only 5mm but does this have any significant effect on the speedo reading?

    I've been doing the maths...
    I am wondering if the 225/45 is actually a misprint and should be 235/45 as that is a closer match to the 215/50
    I've also noticed that both Good Year and Toyo also use the same alternative 235/45 to the 215/50 when you use their tyre chooser

    So will a 245mm tyre actual fit on the rim? that fitted the 215?

    Thats almost 30mm wider?

    It would depend on the aspect, but I have checked and the 215/50, 225/45 and 235/45 will all fit
