The 20-year-old will get his campaign underway later today in the qualifying round of the slopestyle event in Sochi, and Nicholls has admitted that he is ready to go at 100% if he needs to.
He told the Yorkshire Post: "My aim is to go out there, have fun, enjoy the experience and land the run and hopefully do well. I'm not going to go there and just do a safe run like you would at the World Cups.
"When you train you try to go at 100% because at least you know if you go full out in training and you do crazy runs, then when you go to a competition you can maybe go to 80 per cent and you're going to land it.
"At the Olympics and I'll go at 80%, knowing if I need to, I've got that extra 20%."
