Can I fit a wider rear tire on my 2009 Street Glide?

While some minor deviations might be possible with aftermarket modifications, fitting a significantly wider rear tire on a 2009 Street Glide typically requires changes to the fender, swingarm, or belt guard. Sticking to the stock 180/65B16 size is recommended for a direct fit.

What is the difference between 180/65B16 and 180/65R16?

The 'B' in 180/65B16 indicates a bias-ply construction, common in older tires. An 'R' signifies a radial tire, which is generally preferred for modern performance due to better heat management and flexibility. Both sizes refer to the same tire dimensions for width, aspect ratio, and rim diameter.

How often should I replace the rear tire on my 2009 Street Glide?

Motorcycle tires should be replaced based on both mileage and age. A common recommendation is every 5,000 to 10,000 miles, or after 5-6 years, whichever comes first. Inspect your tire regularly for wear indicators, cracks, or damage.

2009 Street Glide Rear Tire Size: The Ultimate Fit Guide

What is the Stock 2009 Street Glide Rear Tire Size?

The standard rear tire size for a 2009 Harley-Davidson Street Glide is 180/65B16. This specification ensures the tire provides the intended balance of contact patch, load capacity, and profile for your motorcycle's weight and intended use, crucial for its characteristic handling and stability.

Matching this is the primary goal.

When selecting a replacement rear tire for your 2009 Street Glide, adhering to this stock size is the safest and most straightforward approach. It guarantees compatibility with your existing wheel rim and suspension geometry. Deviating without understanding the implications can compromise the bike's ride quality, braking performance, and overall safety.

The 180 denotes the tire's width in millimeters across its tread. The 65 represents the aspect ratio, indicating the tire's sidewall height is 65% of its width. The 'B' signifies a 'Bias-ply' construction, though radial tires are common replacements and generally superior. Finally, 16 is the rim diameter in inches that the tire is designed to fit.

Understanding this tire size is fundamental to maintaining your motorcycle's designed performance characteristics. It ensures the tire works harmoniously with the chassis, suspension, and braking systems. This precision is paramount for a predictable and enjoyable riding experience.

A correctly sized tire ensures the bike leans and tracks as intended.

Factors Influencing Your Rear Tire Choice

Beyond the factory specification, several factors influence the best rear tire choice for your 2009 Street Glide, especially if you're considering alternatives or upgrades.

Rim Width and Tire Compatibility

While the 180/65B16 is the stock size, the width of your rear wheel rim is a critical factor. Most 16-inch Harley-Davidson touring rims are designed to accommodate a 180mm tire. However, always verify your rim's specific width. A tire that is too wide or too narrow for the rim can lead to improper seating, excessive sidewall flex, and premature wear.

Tire Construction: Bias-Ply vs. Radial

The original tire may have been bias-ply, indicated by 'B' in the size. Modern replacements are often radial. Radial tires generally offer better heat dissipation, longer tread life, and superior grip, especially in wet conditions. They are a recommended upgrade for most riders, provided they are dimensionally equivalent to the stock size.

Riding Style and Conditions

Consider how and where you ride. If you primarily cruise highways, a tire focused on longevity and stability might be best. For those who encounter varied weather or enjoy spirited canyon carving, a tire with enhanced wet-weather grip and cornering performance might be a higher priority. Our analysis indicates that rider preference plays a significant role here.

Choosing the right tire is more than just matching numbers.

The most critical factor in tire selection is ensuring it matches both the rim's dimensions and the motorcycle's intended load and performance envelope.

Inspect your current rear tire for any unusual wear patterns. Uneven wear can indicate issues with suspension, alignment, or incorrect tire pressure, which must be addressed before installing new rubber.

Load Rating and Speed Index

Ensure the replacement tire meets or exceeds the original load rating and speed index. These ratings are essential for safety, especially when carrying a passenger or luggage. While specific figures for the 2009 model should be checked against the tire manufacturer's data, the stock specification provides a baseline.

Selecting and Purchasing Your Rear Tire

Now that you understand the specifications and influencing factors, let's look at how to make your purchase.

Where to Find the Right Tire

You have several reliable avenues for purchasing the correct 2009 Street Glide rear tire size:

Harley-Davidson Dealerships: Offer OEM-specified tires, ensuring perfect fitment and quality, though often at a premium price.
Specialty Motorcycle Tire Retailers: Websites and physical stores dedicated to motorcycle tires carry a wide range of brands and models, often with expert advice.
Online Motorcycle Parts Retailers: Large online stores offer competitive pricing and a vast selection, but ensure you're buying from a reputable seller.

It is imperative to acknowledge the importance of choosing a tire from a reputable brand known for quality and durability in the motorcycle segment. Brands like Dunlop, Michelin, and Metzeler are common choices for Harley-Davidson touring bikes.

Whenever possible, purchase tires manufactured within the last 12-18 months. Tire age, not just mileage, affects performance and safety. Look for the DOT date code on the sidewall.

Installation Considerations

While you can purchase tires online, installation is a critical step. Most riders opt for professional installation at a motorcycle shop. They have the correct equipment to mount and balance the tire safely, ensuring optimal performance and preventing damage to the wheel or tire during the process. Balancing is crucial for a smooth ride and even tire wear.

Don't overlook the importance of proper installation.
