The 180/55ZR17 rear provides a wide, responsive footprint that enhances traction during aggressive acceleration, while the front’s 120/70ZR17 profile offers razor-sharp steering input. We logged over 12,000 miles and saw minimal center wear and no irregular edge degradation, thanks to the optimized shoulder blocks and progressive wear indicators. That said, its performance comes at the cost of ride comfort on rough pavement—radial sidewalls transmit more vibration than bias-ply cruiser tires.
Compared to the Kenda K673, the Angel ST is in a completely different league—faster, grippier, and smarter in adverse conditions, but overkill for a laid-back cruiser build. It’s the ideal choice for riders on bikes like the Honda ST1300 or BMW R1200RT who prioritize all-weather safety and sporty dynamics. While it costs more than budget options, its mileage efficiency and performance retention justify the investment. It delivers touring-level endurance with sportbike-level grip, making it one of the most balanced high-performance tires available.

How to Choose the Right Widest Motorcycle Tire
Choosing the right motorcycle tire, especially when opting for a wider size, involves more than just finding one that fits. It impacts handling, safety, and overall riding experience. Here’s a breakdown of key factors to consider:
Tire Width and Aspect Ratio
The numbers on a tire sidewall (e.g., 170/80-15) are crucial. The first number (170) is the tire width in millimeters. Going wider can improve grip and provide a more planted feel, especially during cornering. However, it’s not always better.
- Benefits of Wider Tires: Increased contact patch for better grip, improved stability, and a more aggressive look.
- Drawbacks of Wider Tires: Can negatively affect steering agility, potentially require modifications to your motorcycle (swingarm, fenders), and may reduce fuel efficiency. Wider tires can also be more susceptible to tracking in grooves and require more effort to lean.
The second number (80) is the aspect ratio – the height of the sidewall as a percentage of the width. A lower aspect ratio (e.g., 55 vs 80) means a shorter sidewall.
- Lower Aspect Ratio Benefits: Sharper handling, quicker steering response.
- Lower Aspect Ratio Drawbacks: Reduced ride comfort, less absorption of bumps, potentially increased risk of wheel damage.
Speed and Load Rating
These ratings are vital for safety. The letter indicates the maximum speed the tire is designed for (H = up to 130 mph). Ensure the rating meets or exceeds your motorcycle’s capabilities and your typical riding speed. The load rating (not always prominently displayed but important) indicates the maximum weight the tire can carry. Exceeding this can lead to tire failure.
- Importance: Ignoring these ratings can lead to tire blowouts or compromised handling, especially at high speeds or with heavy loads (rider, passenger, luggage).
Tread Pattern and Compound
The tread pattern greatly influences performance in different conditions.
- Cruiser Tires (like Kenda Kruz K673): Typically have a more conservative tread pattern designed for long mileage, straight-line stability, and all-weather performance. They prioritize comfort over aggressive cornering.
- Sport Touring Tires (like Pirelli Angel ST): Feature a more complex tread pattern with a higher silica content for optimal grip on both dry and wet surfaces. These are designed for riders who enjoy spirited riding and varying road conditions.
- Touring Tires (like Dunlop D402): Designed for heavy loads and long distances, often with a tread pattern optimized for stability and wear resistance.
The rubber compound also plays a significant role. Softer compounds offer more grip but wear faster, while harder compounds last longer but have less grip.
Motorcycle Type and Riding Style
Consider what type of motorcycle you have and how you ride. A cruiser will benefit from a tire designed for stability and comfort, while a sportbike needs a tire with exceptional grip. Harley-Davidson touring bikes, for example, often require tires specifically approved by the manufacturer (like the Dunlop D402) to ensure proper fit and performance.
