It's not a big deal to not find any record of Pilate's life in Rome, although you can find him recorded on other documents.
For example it was found a latin inscription about Pilate in Judea, Caesarea Maritima, that says "S TIBERIÉUM PO]NTIUS PILATUS PRAEF]ECTUS IUDA[EA]E FECIT D]E[DICAVIT"
Translated into modern english means "...Tiberius, Pontius Pilate prefect of Judea has dedicated..." The rest was damage thus impossible for me to translated what it says before and after that.
Moreover there is a letter from King Herod Agrippa I (in Philo, Legatio to Caium, 38) describes Pilate as "relentless, without respect, stubborn".
Not to speak that in central Italy there are a lot of stories about him and about his death place, but since they are all oral tradition with no objective facts, I'll treat them as other oral tradition, thus of no historical value. So your point is totally pointless.
We know that there is no proof of the existence of Umar, Ali, Muhammad's wives ect. Does this mean they never existited? No, it does not mean anything, though it's strange and funny that Arabs have no recorded any relevant islamic figures on documents...
Of course Hadiths and oral traditions are of no value.
