Tyre pulling is today firmly established as the way to train all year for polar expeditions where you are pulling a pulk. Three months before our Hardangervidda crossing, I have started training with tyres myself. I may be a bit late, to be honest, but this will still be valuable exercise for me. There are many blog posts out there on the basics of tyre pulling. The best I know is The fine art of pulling rubber tyres by Børge Ousland. You may as well learn the basics from the best instead of from me, so I am going to focus on the things I learned on top of that article.
