Slot Car Corner has new 15 x 12 wheels that are designed to take inserts.
These are as wide as the F1 wheels Alexis mentions, but are a bigger diameter.

They also have gold 15x12's 5 spokes that are a good resemblance of the Ferrari wheel..

If you need to go wider than 12mm, you might want to look at the rear wheels from Carrera's Can Am Porsche
Hope this helps...
