I'm looking into getting run flats for our upcoming iQ on the accessory mag wheel shown on the Scion.com site. The only one I can find that is 175/60R16 is a Dunlop Winter/Snow tire. Both Pirelli and Bridgestone offer a 205/55R16 but that requires a 5.5"-7.5" width rim.

Does any one know the width of that rim? The stock steel rims are 5" wide.

 

My dealer got the Scion accessory rims in and they're 5" wide the same as the steel rims.

When it looked like they were going to be delayed I investigated putting on 5Axis rims and Pirelli run flats but after seeing the Scion rims and factoring in the additional $1,000 and the possibility of a harsh ride I decided to go with the Scion. Should get them on this week.

As a side note, I exchanged some emails with 5Axis and they were prompt and very helpful.

 

The stock 16" steel wheels are 6" wide.

 

Perfect size wheels for these cars is a 17-7 with a 45 offset using a 205-45-17 tire.
This will keep everything at stock geometry no rubbing and correct speedo readings .
