A 295 tire is my target width for the rear, and it is designed for 9.5'-11" with an optimal 10" rim width.
So a 14" is pretty much for show in my case. Could you stretch a 335 or 345 tire on a 14" rim, sure...but why. What does one gain?

no, that is the measuring rim. The best performance would come from using the widest wheel, 13"
for a 295/30 x18 RS you would want to use an 11" wheel, the max it is spec'ed for.
