The recommended tire for the Jack Pine Kenda AMA National Enduro in Michigan is the Millville II, this tire works great in sand to intermediate conditions in Michigan. The alternate tire will be the Southwick II. The Kenda rider support boxes will be at this round, they will be at the first and second gas truck. The boxes contain Kenda Tuff-Tubes, bike stand, tools, tire spoons and air compressor. The tubes are on the honor system, just stop by after the race and pay for what you use. The support boxes are for all the riders regardless of brand tire you run. Tim Anderson the trackside vendor for Kenda tires will have a selection of Kenda tires and tubes, including the Kenda Super Tuff Tubes. We have restocked on the new Equilibrium tires, the 19 inch size is now availible. All feedback has been extremely positive on this new type of tire.
