Dunlop D401 Front Tire - All Sizes & Sidewalls AvailableThe Tire That Came On Your Harley From The Factory If you ride a Harley, you have probably already seen these tires. Because they came on the bike from the factory. The D401 has been Harley-Davidson's front tire of choice for years. And for good reason.Dunlop built this tire specifically around what cruiser bikes need. Stable steering. Consistent wear. Grip you can trust in the rain as much as the dry. The tread compound is formulated for cruiser use. Not borrowed from a sport tire or a touring tire and relabeled. That means it behaves predictably under the weight and geometry of a V-twin. And it does not go off a cliff in wet conditions the way some harder compounds do.Why The D401? One thing worth calling out. The tread profile is computer-optimized specifically to fight that center cupping issue that plagues a lot of front cruiser tires. It is a small detail that makes a real difference over the life of the tire.Harley-Davidson branding is molded into the sidewall. It is the only tire brand licensed to do that. That tells you something about how tight the relationship between Dunlop and HD actually is.Available Sizes Four variants cover the most common front fitments on Harley-Davidson cruisers:Part NumberSizeLoad / SpeedSidewallDUN45064660100/90-19 M/C 57H TL57 / HBlack WallDUN45064215100/90-19 M/C 57H TL57 / HWide WhitewallDUN45064638130/90B16 M/C 73H TL73 / HBlack WallDUN4506454590/90-19 M/C 52H TL52 / HBlack WallWide Whitewall The Wide Whitewall variant is the same tire mechanically.
