GR Yaris GR Yaris Tire Size Guide

[AHSwede]

Have not seen it mentioned anywhere, but does anyone know the largest tire size (diameter/width) that will fit the stock rim, and not rub the wheel well on stock suspension? I have realized that for the dirt roads I drive on, I would love a little bit more clearance and a taller tire is the easiest way to do it. I would prefer to keep the stock suspension and rims. Was hoping to get at least 1-2cm increase in ride height.
