Michelin Bib Mousse are great for preventing flats but a pain to install. I was happy to learn there is a tire service to mount these things during the rally. The first two we installed were rears, one on the suggested 2.5″ rim, the other on a 2.15 rim. The smaller rim combined with a rim lock was not easy, made me want to never have to do it again. Rob and I mounted a front the other day, with plenty of lube and no beed lock it was surprisingly easy.
