I wanted a Tera World with a sunroof, and the 20" rims always seemed to be bundled in with the cars I wanted to buy, so here I am.
Was my situation too, wanted the Tera
After a few months driving on the cr@p roads in the DFW area, putting bends on the inside of all four rims, and then hitting a major pothole and putting pinch blisters in two tires, ruining them, I dumped the 20's. Was going to get a set of the 19" Rial X 10-I wheels from Tirerack, but found a good set of used OEM i3 wheels on the local Craig's list for $300 for the set
The low sidewall summer/sport tires just don't have enough depth for protection from bad roads. Plus I like the ride on the 19" higher sidewall all-seasons much better. The 20's have a real harsh ride compared to the 19's
