"At Phillip Island it was a bit hard because Dunlop aren't doing anything wrong - they've made a fast, grippy tyre but the set-up that it requires goes out of the parameters that they give us so it becomes a bit dangerous.
"You are basically de-tuning your car to make the tyre last.
"At a place like Bathurst safety is paramount. You are doing 200km/hr over the top of the hill and there is no run off so you definitely don't want a tyre failure."
The move sparked some criticism from Erebus driver David Reynolds who thinks teams that had the set-up right at Phillip Island are not being rewarded.
"That's a point as well," van Gisbergen said. "We could de-tune the car a lot and make it safe but that is beside the point of it all.
"Someone is going to get greedy and want to go a bit faster and risk it a little more and they could crash and maybe take David Reynolds with them."
The next round of the championship is at Queensland Raceway next week.
