Harley Davidson has brought many legendary, popular, and reliable motorcycles. These motorbikes have particular wheel and rim sizes. Plus, the different wheel and rim sizes mean you can interchange any of these models.
So, you must understand the Harley wheel interchange chart. It will help you know the wheel fitment of the different Harley Davidson models. You will also understand the custom rim and wheel available for the specific motorcycle model.
So, let’s jump deep into the discussion to find which Harley wheel is interchangeable with which model. But before that, you should know the facts linked with wheel size.
Tips On How To Understand Wheel and Tire Size Of Motorcycle
You should know its sizing when you plan to interchange tires and rims of different Harley motorcycles. The size of any motorcycle and automobile wheel is described using a few letters and numbers. All these numbers and letters have distinctive meanings.
These numbers and letters express the width of the tire in millimeters, its height in inches, and the rim’s diameter. The numbers are important as they control the fitment of the tire and its performance with a specific motorcycle model.
Width Of The Tire
The average width of a motorcycle tire can be anywhere from 100mm to 300mm. As the number increases, the tire becomes wider or taller. Also, a wider tire will have better traction and control on the roads.
On the 18″ sports bike, the common tire size will be 170mm and 180mm for the front and rear wheels, respectively. You will find 220/180 and 200/160 wheel sizes for the cruiser’s rear and front wheels. As you see, the front wheel is less wide than the rear wheel.
The aspect ratio of the wheel has two parts. These are:
- Height of the tire profile
- Tread percentage against the tire’s width
For instance, if the tire width is 120mm and its tread percentage is 70% for the wheel, its aspect ratio will be 84mm. As the aspect ratio increase, the tire becomes taller.
Also, taller tires usually are more roundish. Taller and rounder wheels offer better stability during braking and motorcycle cornering. It is useful when riding Harley Davidson motorcycles at speed in hilly regions.
The drawback of the taller profile is that it makes the wheels and tires heavier.
Rim diameter is straightforward to understand as it refers to the wheel’s diameter. It is expressed in inches. The diameter suggests whether or not the tire will fit in the wheel.
Construction Of The Tire
Tires are mainly of two types, depending on the construction style. These are:
Radial offers better performance with its improved puncture resistance capacity. It makes the tire more durable as well. However, these tires are costlier to replace. So, many people don’t like these tires for the costly replacement.
Bias-ply tires have a softer construction. It is ideal for long-distance rides. Also, softer tires will be hugely beneficial for riding on off-roads. The tradeoff for these tires is less stability.
The speed rating expresses the maximum speed a wheelset of the motorcycle can accommodate. The speed limit has three different aspects. These are:
- Maximum design speed is dependent on the handling ability and considerations of different road conditions.
- Then, there’s the lower speed limit. It corresponds with the treadwear and ride-ability of the wheel in standard conditions. The rating is measured at 60MPH speed.
- The lowest limit for the speed rating is set at 45MPH.
The speed rating of the wheel is expressed with code letters.
|Code Letter||Max Speed|
|Z/ZR||149+ MPH (240+ KPH)|
The tire also has a definite load-bearing capacity. It is expressed as the load rating of the wheel and tire. Also, the load rating is expressed in “Number” coding. Also, each number expresses a definite load-bearing capacity for the tires.
It starts at the “33” code and goes up to 99. The load capacity of the wheels typically starts at 254 pounds (115KG). The highest load rating capacity for the motorcycle and automobiles is 1323 pounds (600KG).
Now that you know the factors associated with the Harley Davidson wheel size let’s check the interchange capacity.
