Specifically engineered as the official co-branded original equipment street tire line for standard classic cruisers and custom V-twins, this tire establishes an absolute balance between high mileage, stable wet-weather tracking, and consistent steering response. Built with an advanced computer-optimized tread profile, it ensures exceptional front-end stability and long, even wear characteristics throughout the entire lifespan of the casing.
Part number 45064215 features a specialized high-performance metric cruiser bias configuration. Meticulously cross-referenced against factory assembly specifications, this 100/90-19 front tire is a verified direct fit for the following cruiser applications running a 19-inch front rim layout:
CRITICAL TUBE TYPE RE-INTEGRATION, COMPOSITE LIMITS, AND BREAK-IN WARNINGS:
**Tubeless vs Tube Type Rim Logic:** This tire features a standard Tubeless (TL) bead design construction. **It can be safely run completely tubeless on modern factory mag/alloy wheels**. However, if your cruiser utilizes traditional chrome spoke or laced wire wheels, **you must install a heavy-duty motorcycle inner tube and fresh rim strip during mounting**. Running a tubeless tire on a spoked wheel without an inner tube will cause immediate, dangerous pressure failure.
**Bias-Ply Construction Frame Warning:** The D401 is a **Bias-Ply** construction tire. It should **never** be mixed on a motorcycle with a rear radial tire, and it cannot be used on heavy touring platforms that were factory-engineered strictly for advanced radial tire tracking geometry. Mixing tire constructions can cause severe chassis instability.
**Load and Speed Rating Compliance:** This casing carries a heavy-duty 57H metric index rating, meaning it is safety-certified to support a maximum static load capacity of 507 lbs at a peak continuous speed of 130 MPH. Do not exceed these structural parameters under full multi-day luggage and passenger weights.
**Critical 100-Mile Tire Break-In Protocol:** Brand new motorcycle tires feature a slick mold-release sheen on the outer tread surface straight from the manufacturing assembly plant. **Riders must exercise extreme caution during the first 100 miles of operation**. Avoid sudden heavy acceleration, hard braking, or aggressive lean angles until the tread compound has been scuffed cleanly against raw pavement to establish full friction traits.
