Im about 600 miles into my recently purchased F800... After a few off-road rides, new tires are definitely being purchased ASAP. The stock pirelli's are crap off-road, since they look to be a street tire. I was going to purchase a set of K60's, but when looking at my current tires to confirm size, they are marked as "tubeless"............ How is this? From all that I read, and according to the dealer, they are tubed tires... Is this a tubeless tire fitted with a tube, or am I missing something here??
