I'm running 165 x 14's on my 2c Berlina, originally she would have been on 155 x 14's but when I put her back on the road in November 1999 I could only get 145 x 14, and although she ran ok she always felt under tyred, with the 165's she rides much better if slightly harsher, but it's improved the handling no end.
Ask anyone who was on the Fulvia Knights Rallye to Turin last year

if you stick with 145's I have a pair of part used FOC, that just need collecting from Central Bedfordshire
