Now that the mtb is in use for the commute to work, its time to start considering what tyres to put on.
Its still got the original fit knobbly tyres, and its rarely gone any distance off road
I'm considering the Schwalbe Marathons, but am wondering about sizes. The current tyres are 26x2.1, and the marathons are available in 26x1.75, and 26x2. Any reasons why I should choose either size over the other?
I've seen a few totally slick tyres as well, but am unsure about those on the slippery roads of London, especially at this (wet) time of year.
