Hi Netters, Robin Wills made a comment on tire size under the heading of speed. He suggested that the 600 x6 makes the KR Look "The bloody KR looks like a Mini with 19" rims on it now, these tyres are huge." There is no doubt that there will be more drag here. But it will work better on grass or a rough field. I had a pair of 600 x8 on mine but it would go slower still and could probably land on a field of boulders. Since the brakes would not fit the present axels I switched to 600 x 6. It may go faster but I will have to forgo the field of boulder and settle for grass.It is all in the eye of the beholder.
