In my quest for the perfect tire for my bicycle tour I have e-mailed one of the biggest manufacturers of quality tires – Schwalbe.
I asked what would be the best tire for a long distance European bicycle tour. Here is the answer:
“Both tires (Marathon Plus and Marathon Supreme) would be an excellent choice for a bicycle tour you are going to do. So I can´t really give you a recommendation for one of these tires, I just can point out some interesting advantages. So if you are searching for a tire featured with best puncture protection and best durability you have to choose the Marathon Plus. This tire is often used for longer journeys and available for a fair price. On the other hand Marathon Supreme offers great performance as to grip and rolling resistance with an acceptable puncture protection and durability. In addition you will save half of the weight compared to Marathon Plus.”
