MU85B16 Conversion: Upgrade Your Tires for Better Performance

As motorcycle enthusiasts, we understand the importance of having the right tire size for your bike. One tire size that often comes up in discussions is the MU85B16. This tire is commonly used on Harley Davidson motorcycles, but what happens when you need to replace it and can’t find the same size? That’s where the MU85B16 conversion comes in.

Understanding tire sizes can be confusing, especially when you’re trying to convert from one size to another. The MU85B16 is a metric tire size that is equivalent to a 140/90B16 tire size. This means that if you can’t find a MU85B16 tire, you can look for a 140/90B16 tire instead. It’s important to note that while these two tire sizes are equivalent, they may not have the same load rating or speed rating.

When it comes to tires, there are different types to choose from depending on your riding style and needs. Some riders prefer hard compound tires for longer wear, while others prefer soft compound tires for better grip. Regardless of the type of tire you choose, it’s important to install and upgrade them properly to ensure your safety on the road.

Understanding Tire Sizes

As motorcycle enthusiasts, we know that tire sizes can be confusing. That’s why we’re here to help you understand tire sizes and conversions. In this section, we’ll cover the basics of tire sizes, metric sizing and conversion, and load and speed ratings.

Metric Sizing and Conversion

Tire sizes are typically expressed in two formats: metric and standard. Metric tire sizes are expressed in millimeters for the width, percentage for the aspect ratio, and inches for the rim diameter. For example, the tire size MU85B16 is a metric size that represents a rear tire with a width of 85 millimeters, an aspect ratio of 85%, and a rim diameter of 16 inches.

If you’re used to standard tire sizes, converting to metric sizes can be confusing. However, it’s important to note that there are conversion charts available to help you make the switch. For example, the MT90B16 tire size is equivalent to a 130/90-16 tire size in metric.

Load and Speed Ratings

Load ratings and speed ratings are important factors to consider when choosing the right tire for your motorcycle. Load ratings indicate the maximum weight the tire can safely support, while speed ratings indicate the maximum speed the tire can safely handle.

Load ratings are expressed as a number from 0 to 279, with higher numbers indicating a higher load capacity. For example, a load rating of 74 means the tire can support up to 827 pounds.

Speed ratings are expressed as a letter from J to (Y), with higher letters indicating a higher speed rating. For example, a speed rating of H means the tire can safely handle speeds up to 130 mph.

It’s important to choose a tire with the appropriate load and speed rating for your motorcycle to ensure safe and reliable performance.

In summary, understanding tire sizes, metric sizing and conversion, and load and speed ratings is very important for any motorcycle enthusiast. By knowing these basics, you can choose the right tire for your motorcycle and enjoy a safe and comfortable ride.

Types of Tires

When it comes to motorcycle tires, there are two main types: radial and bias ply. Radial tires are constructed with the plies running perpendicular to the direction of travel, while bias ply tires have the plies running diagonally. Radial tires are known for their better handling and longer lifespan, while bias ply tires are more affordable and provide a smoother ride.

Radial Vs Bias Ply

Radial tires are more popular among riders due to their superior handling and stability. They offer a larger contact patch with the road, which results in better grip and traction. This makes them ideal for high-performance bikes and riders who enjoy taking corners at high speeds. Radial tires also have a longer lifespan than bias ply tires, making them a better investment in the long run.

Bias ply tires, on the other hand, are more affordable and provide a smoother ride. They are known for their durability and resistance to punctures. They are also easier to repair than radial tires. Bias ply tires are a good choice for riders who prioritize comfort and affordability over performance.

Tread Patterns and Positions

The tread pattern and position of a tire can also affect its performance. Tread patterns are designed to provide better traction in different types of terrain. For example, tires with a more aggressive tread pattern are better suited for off-road riding, while tires with a smoother tread pattern are better for street riding.

The position of the tread can also affect the tire’s performance. Front tires usually have a shallower tread depth than rear tires, as they are responsible for steering and require better handling. Rear tires, on the other hand, have a deeper tread depth to provide better traction and stability.

In conclusion, choosing the right tire for your motorcycle is very important. Radial tires are ideal for high-performance bikes and riders who prioritize handling and stability, while bias ply tires are more affordable and provide a smoother ride. The tread pattern and position can also affect the tire’s performance, so it’s important to choose the right tire for your riding style and needs.

Installation and Upgrade

Fit and Installation

When it comes to installing and upgrading the MU85B16 tire, it is very important to ensure that the tire fits properly on the rim size of your Harley. The recommended rim size for this tire is 16 inches, and it is designed to fit on the rear wheel of most Harley models. However, it is always a good idea to check your owner’s manual or consult with a professional mechanic to ensure that the tire is compatible with your specific model.

Once you have determined that the MU85B16 tire is the right fit for your Harley, the next step is to install it properly. This process involves removing the old tire, mounting the new tire onto the rim, and balancing the wheel to ensure a smooth ride. It is important to follow the manufacturer’s instructions carefully during this process, as any mistakes can lead to poor performance or even dangerous handling.

Upgrading Tires

If you are looking to upgrade your tires, there are a few things to keep in mind. First, you will want to consider the type of riding you will be doing. If you primarily ride on the street, you may want to consider upgrading to wider street tires that offer better handling and traction. On the other hand, if you do a lot of touring or off-road riding, you may want to consider upgrading to tires with more aggressive tread patterns.

Another factor to consider when upgrading your tires is the color and style. Many riders opt for wide white wall tires for a classic look, while others prefer sleek black tires for a more modern aesthetic. It is important to choose a tire that not only looks great but also performs well and meets your specific needs.

If you are upgrading to a wider tire, it is important to keep in mind that you may need to remove the lower belt guard to clear the tire. This is especially true if you are upgrading to a tire that is significantly wider than the stock tire. It is always a good idea to consult with a professional mechanic or experienced rider before making any major upgrades to your motorcycle.

In conclusion, upgrading to the MU85B16 tire can be a great way to improve the performance and style of your Harley. However, it is important to ensure that the tire fits properly and is installed correctly to ensure safe and reliable handling. By following the manufacturer’s instructions and consulting with experts when necessary, you can enjoy the benefits of a high-quality tire upgrade for years to come.
