I have always used levers and up to now got away with it. The video is really good and I will try that method next time I fit M+s, which won't be long. I fitted 2 a few hundred miles apart last time and have got around 5,000 miles out f them, as opposed to around 2,000 from the Specialized Armadillos that my bike was fitted with when new. I had noticed they were getting worn quite smooth recently and yesterday I had the first puncture with them and was about to d a roadside repair, but then realised I was about half a mile from an LBS so thought why not go and replace my worn tyre now. The shop fitted one there and then and charged me £6 for doing so. Only thing is the valve on the new tube is very short and when I went to check the pressure this morning I can't get my pump to grip it, so now I am going to replace the rear worn tyre with another M+ and put in another tube with a longer valve in the front one.
