I am starting a wiki entry on tires for dual sport adventure bikes. One on each diameter, 21" and 19" fronts, 18" and 17" rears. I though this might be a good place for people to share their experiences with different types of tyres.... Why add them to the wiki? Well people who join after the discussion, who are away while discussions take place or don't want to search through a load of post to find the good bits can read the tyre wiki. If the wiki is popular then other things could be added e.g. panniers, tank bags, sleeping bags, tents, .... oh chairs, food.
