“It was tight removing it,” officer Scott Murdoch said.
“We would have preferred to cut the tyre and leave the antlers for his rutting activity, but the situation was dynamic and we had to just get the tyre off in any way possible.”
The elk was first spotted with the tyre more than two years ago, during a wildlife survey.

But officers waited years for enough sightings to track the elk and free it.
“This elk was difficult to find, and harder to get close to,” Mr Murdoch said.
Speaking in 2020 about how the elk may have wound up like that, Mr Murdoch speculated it would have become stuck while the elk was young, before it grew antlers.
“It could really have been a number of things, but it would have had to be in the winter months when the elk don’t have antlers,” he said.
The 270-kilogram elk was spotted with a herd of others over the weekend, before officers were able to successfully sedate it.
It was the fourth attempt made in the past week to help the elk.
By removing the tyre, officials estimated the elk shed about 16 kilograms, as the tyre was packed with dirt and pine needles.
They say they have seen deer, elk, moose, bears and other wildlife become entangled in a number of items, including swing sets, hammocks, clotheslines, decorative or holiday lighting, furniture, tomato cages, chicken feeders, laundry baskets, soccer goals and volleyball nets.
