Although it is obviously that no tyre could have repelled that puncture, I have to admit that I am not so sure Marathon Plus are so great, or maybe to be more accurate not so good for users of smaller wheeled bikes i.e. those with 20" rims and less.
On smaller rims they are a nightmare to fit and often the bead gets damaged when fitting or removing the tyre. This is actually worse as what happens is the metal bead is exposed where the rubber covering is scraped off and the coiled wrapped round wire, is burred over.
Initally the tyre eventually goes on and all looks great. Then over the next few months, especially in wet weather, the bead starts to rust. This then ends up rubbing the inner tube and eventaully a tiny puncture develops, usually ending up with the tyre going down over night. I have had this happen three times overall on two of my bikes over a 12 month period. I guess this is better than a roadside punture though.
Fortunately my tyre fitting technique has improved to a point where I can get them on without levers though levers are still required to remove them.
I have been trying other tyres with kevlar and nylon bands in them and so far they have proved to be as punture resistant as my Plus's.
I guess tyre selection is a personal thing and I am tending to prefer faster rolling tyres these days to heavy full pucture resistant ones. Then again where wheel removal is required for us ebike users, the objective must surely be to minimise punctures given the hassle that often involves. I know you can fix a punture with a wheel in situ but its often hard to identify the pucture site unless the tube is submersed in water. Its always easier to carrier a spare tube, whip the old one out, refit the new one and repair the old one at leisure when you are home.
