I have a completely stock 2001 Tiburon and would like some information on what offset and tire size will work( no fender rubbing, no spacers, no fender modification) if I go to 17 inch wheels. Thanks, Victor.

check the "web links" section from the main page

hope those links help

If you have 17's with a 42 offset, you should not rub if you are using a 205 tire, if you go 215 tire you will rub a little bit when the wheels are turned and the suspension is compressed.
