Well done to Tony for holding his own and giving a great demonstration in front of a room full of people !
I like a good tyre video. You can always pick up the odd extra handy tip.
I still have much work to polish my skills for sure . From what experience i have, my advice to a newbie would be; 3 tyre levers really helps and take small bites. A little spray of lube goes along away. I like using window cleaner. It has an alcohol content making it quick to dry and ready to roll.
If your finding it hard work, take 5 mins time out and re-evaluate things. The process really is about technique as opposed to brute force as Tony effortlessly shows in the video. I must remember this myself when i come to install a taller, stiffer tyre next, including surprisingly my first ever install of rim locks
