Had to drive up a steep road that required chains or traction tyres. It took my boyfriend and I about 15 minutes to put them on and 10 to take them off. It took a bit of trial and error and wasn't as easy as the video shows, but I think next time I get familiar with them it will take a little less time. I love that I can stow it in the trunk on top of the spare wheel and have it there when I need it.
