see glhs386 response above ^^^
Measuring rim width for a 245/50-16 is 7.5", an inch narrower than 8.5" measuring rim for a 245/40-17.
Rim width range for 245/50-16 is 7" to 8.5"
Rim width range for 245/40-17 is 8" to 9.5"
For a *handling* intensive fitment, you kinda want to be on the wide end of the rim width range.
17x8 is not a good wheel width for a 245/40-17 IMO. It is the narrowest allowed for that tire size. I'm running 245/40-17s on 9" wheels for street/track.
