Dunlop Harley-Davidson D402 Tires

Dunlop D402: The Official Harley-Davidson Touring Tire

The Dunlop D402 holds a unique place in the V-Twin world as the only tire designed in collaboration with Harley-Davidson for their heavy-duty touring lineup. Unlike “universal” cruiser tires, the D402 was built specifically to complement the chassis and suspension of Harley-Davidson Touring models. It is the tire that came on your bike from the showroom floor, engineered to deliver the exact ride quality, stability, and safety margins that H-D factory engineers intended for the Electra Glide, Ultra Classic, and Road King.

Built for the Heavyweight Long Haul

The engineering behind the D402 centers on structural integrity. Because full-dress tourers carry immense weight—especially when loaded with a passenger and luggage—the D402 features a three-ply polyester casing reinforced with two fiberglass belts. This “bias-belted” construction minimizes tire deformation under load, which is critical for preventing high-speed wobbles and ensuring predictable tracking through corners. The computer-optimized tread profile is designed to provide a consistent contact patch, giving you a “planted” feel whether you are cruising at 80 mph on the interstate or navigating a parking lot at low speeds.

Expert Advice: Why Stick with the D402?

Riders often ask if they should switch to the newer American Elite or stay with the D402. Pro Tip: If you love the “factory feel” of your bike and want the peace of mind that comes with 100% OE compliance, the D402 is your best bet. It is specifically tuned to the dampening characteristics of H-D air shocks and late-model emulsion shocks. Maintenance Note: To avoid the common “cupping” issue associated with heavy tourers, you must be strict with your cold tire pressure. For a fully loaded Road King or Ultra, we recommend 36 PSI in the front and 40 PSI in the rear. Checking these levels before every trip is the single best way to ensure you reach the 10,000+ mile potential of this tire.

The Professional Aesthetic Choice

Beyond performance, the Dunlop D402 is about the look. For many purists, a Harley-Davidson simply doesn’t look right without the official logo stamped on the rubber. Available in several sidewall configurations, including the striking Wide Whitewall, the D402 allows you to maintain the showroom-fresh appearance of your bike while benefiting from the most tested carcass in the industry. It is a tire built on decades of partnership and millions of miles of real-world touring experience.

Important Fitment Note: Always check your Load Index. The D402 is a “heavy-duty” tire. If you are replacing tires on a smaller cruiser or Sportster, the D401 or D404 may be more appropriate for your bike’s weight class.
