Speaking to the F1 Nation podcast, Allison shared what he believed were the reasons for a below-par performance.
"The main issue was hot rear tyres which would give you a snappier end and would give you the sort of tyre degradation we saw," he said.
"But also, an annoying amount of understeer. When you've got a balance that's all at sea like that, it's very easy to nibble away with every bit of throttle you put down, every turn of the wheel, a bit of the tyres.
"The tyres for everybody were tender here and we got it in a place where a single lap was ok. Very quickly became more than mediocre as we gobbled our tyres up and that's normally a strength of ours so particularly upsetting to weather that storm here."
Mercedes will be thankful that the upcoming Las Vegas Grand Prix is being held at a relatively chilly time of year, with temperatures expected to be half that experienced during the race in Brazil.
Indeed, the tyre benefit provided could help the Silver Arrows who, alongside their competitors, will have to trim a significant amount of downforce to prepare for the long straights.
