Maybe, but their other reputed qualities are not so admirable, i.e Heavy beyond belief (I once picked one up in a branch of
Halfords just out of curiosity. I quickly put it back down again before my arm broke [This is half true, obviously my arm was not at risk of breaking but the weight was so shocking I had to check I hadn't accidentally picked up two tyres bundled together or inside each other]), harsh ride, questionable grip/handling and the real one of notoriety is the reluctance to go on/off the rim for fitting or if you do get a flat tyre for any reason. There is even Youtube videos showing the required technique and additional tools required to fit one without resorting to uncontrolled physical violence
If you are the kind of person who gets your helpful LBS to fit your new tyres and fix any punctures and would phone for a family member to rescue you in the case of a flat tyre then the Marathons might be for you, but otherwise I would recomend using something a bit more user friendly.
