A 1-0 victory at Wycombe on New Year's Day was their eighth road win of the season and the Grecians have taken 25 of their 38 points away from home including eye-catching wins at the likes of Gillingham, Bradford and Oxford.
"The thing that will fill us with most confidence is the way we are playing away from home," Tisdale said. "There is always the opportunity for me to ask the players to draw on the experience of some really efficient away form this year.
"It'll be about us continuing the pattern and the intent that we show away from home that is working regardless of who we play."
In contrast to City's impressive displays around the country during the first half of the season, the Minstermen have struggled at home with only four npower League Two wins at Bootham Crescent.
Tisdale, whose side have not won at York since 2005, understands the frustration of inconsistent home form having overseen just three victories at St James Park this season.
"I empathise with York's home record, we find ourselves in the same situation," he said. "You always run the risk that they are going to find the key to it soon, like we are ourselves.
"I've not won there and I've managed there twice, in 2006 and 2008. But this has been a season for beating teams that people have told me we haven't beaten on their ground for a long time so why not York City?"
