Dunlop D404 Tires

Dunlop D404: The Versatile Standard for Cruiser Performance

The Dunlop D404 has earned its reputation as a staple in the motorcycle community. Derived from Dunlop’s legendary Harley-Davidson original equipment (OE) tread patterns, the D404 is designed to offer a balanced, comfortable ride for a wide variety of Metric Cruisers, Standard bikes, and older V-Twins. If you are looking for a tire that delivers predictable handling and solid traction without the premium price tag of a specialized touring tire, the D404 is the industry benchmark.

Tread Design & Wet Weather Confidence

Engineered with an offset center groove, the D404 provides excellent straight-line stability, helping to prevent the bike from “hunting” or wandering on rain grooves and metal grate bridges. This is paired with a tread compound that balances durability with grip. The deep lateral grooves are specifically shaped to channel water away from the contact patch, maintaining a high level of “mechanical grip” during sudden rain showers. Whether you are navigating city streets or cruising rural backroads, the D404 keeps you planted and in control.

Expert Fitment Warning: D404 vs. D401/D402

There is a common misconception that the D404 is a direct replacement for all Harley-Davidson models because it looks like the OE tires. Pro Tip: While the D404 is excellent for Sportsters and lighter cruisers, it is not recommended for heavy Harley Touring bikes like the Road Glide or Ultra Classic. The D404 lacks the additional “bias-belted” plies found in the D401 and D402, meaning it has a lower load rating. Maintenance Note: To maximize the 8,000 to 11,000-mile lifespan of a D404, keeping your PSI at the manufacturer’s recommended level is non-negotiable. Bias-ply tires generate more internal heat than radials; running even 5 PSI low can cause the tire to wear prematurely or develop a “choppy” tread pattern.

The Best Value in the Cruiser Market

For the rider who does not need a 20,000-mile “super-touring” tire, the Dunlop D404 represents the smartest investment. It provides the “Dunlop Feel”—stiff sidewalls and predictable feedback—at a fraction of the cost of premium competitors. It is the perfect choice for riders who want to refresh their bike’s handling and appearance while staying on a budget. From Shadows and Vulcans to Rebels and Sportsters, the D404 remains the world’s most trusted “workhorse” tire.

Always ensure you check your tube requirements. Many D404 sizes are “Tubeless” (TL), but must be used with a tube if you are running spoke wheels.
