It looks like the 5 x 100 bolt pattern with "H" offset is the same for the '99 and newer Jettas that came stock with 15" steel wheels. Tire rack recommends 15 and 16" steel wheels for the tC.

Has anyone used that wheel as a winter option for the tC?

 

should work. but the jettas/gti's have bigger center hubs so u might need a hub spacer to fit it.

 

i think u can use the same steelies from 04+ Corolla...

 

Here is good site to find out info on wheel sizes. Just in case you didn't know about it.
