Today's fruitless search for Bullitt wheels, LOL

Top photo is the present tire OAL width sidewall, about 9 5/8"

What you are showing here is the section width. I have a set of 225/60/15 that are 9.5" wide at the section width. 245/45/17 will be around 9.6 due to the shorter wall of the 45 tire. The shorter the wall the less section width "bulge".

The front will be your biggest issue, depending on the ride height you want.
