[m1adam]

wheel size does affect ur speedo reading wat is ur wheel size?

 

[zzainudin]

i'm using 205/45/R16 tyres...
how the diameter?

Formula from manual apexi

Corr. Value = New Tyre Dia x 100
Factory Tire Dia

so if std wira come with 175/60/R13 right..

 

[m1adam]

mayb theres some thing wrong in the calculation

 

[zzainudin]

Nevermind..tomorrow i'll send it to setting again

thanks my friend
