Id say 90% of the F14 setups we've done out there is with a 255/35/19 since the 19x9.5 +20 fronts fits semi aggressive. The mild stretch on the 255 allows you to get pretty low without any rubbing.
As long as you aren't trying to slam it and tuck tire, the 265/35/19 in front fits.
Heres 265/35/19 RE-11s on the 9.5 fronts.

Let me know which you prefer Johnathan, and we'll get your F14 build going
