Visited Eneous 1Utama yesterday for a closer look of tyres size available..looks like they have many Falken brand. Currently Im using 205/55/16, plan to upgrade with bigger wheels up 18 inches with low profile tyres from 40-45 series.. I refer tyre calculation over this link http://www.kouki.co.uk/utilities/visual-tyre-size-calculator .
So if I upgrage to 18" with tyre size 225/40/18 my speedo meter will read less 0.5km/hr than the actuall speed. Should I consider 215/45/18... speedo meter reading will read less by 1.8km/hr from actuall speed.
The price of the tyre ain't cheap as well!! Not yet inclusive of the rims....OZ rims is in my list.
