CRITICAL LOAD SEGREGATION, TUBELESS LOGIC, 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 Harley-Davidson 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 a tube will cause immediate, dangerous pressure failure.
**Load and Speed Rating Compliance:** This casing carries a 73H metric index rating, meaning it is safety-certified to support a maximum static load capacity of 805 lbs at a peak continuous speed of 130 MPH. Do not exceed these parameters under full luggage and passenger weights.
**Critical 100-Mile Tire Break-In Protocol:** Brand new tires feature a slick mold-release sheen on the outer tread surface straight from the 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.
