Looking at putting some wheels on the new bus to make it a bit more bearable to drive. I am pondering a nice staggered setup of 8x18" on the front and 9x18" on the rear, but information is pretty scarce on Touran's, let alone whether or not the rear arches will take a 9J rim or not.

Can anyone shed any light on the subject? Before I make what could be an expensive mistake!
