it seems as though most of these stupid trends are pioneered by VW owners. not saying they cant look nice sometimes, but just the overall idea of everything they come up with is just so stupid...
like tire stretching that ReplicaR mentioned. tires are the one thing i would never want to mess around with, especially when when you talk about stretching them. i totaled my last car because of a blown tire. most wheel sizes have "play" with the min/max tire sizes they can handle, but i wouldnt go exceeding those sizes in either direction.
