motorcycle tyre upsize calculator

Out of all the modifications you can make to a motorcycle, putting on larger tires is one of the most profound. This can improve traction, enhance the appearance and even change how it handles. However, when upsizing your tires there are more factors than just buying a bigger tire and slapping it on. The process includes calculations to ensure safety as well as performance isn’t compromised.

This complete guide will take you through everything there is about up-sizing your motorcycle’s tyres and introduce Motorcycle Tire Upsize Calculator which is an essential part in this process.

Knowing Motorcycle Tyre Sizes

The first thing you need before using a tyre upsize calculator is understanding how motorcycle tyre sizes work. Normally, they’re expressed in numbers like 120/70-17. Every part of this code gives information about the tire.

Breaking down the code

Width : The width of the tyre represented by the first number (e.g., 120 millimeters)

Aspect Ratio : The second number (70) gives sidewall height as percentage of width

Rim Diameter : The rim diameter indicated by last figure (17 inches)

Radial vs Bias-Ply Tyres

Tyres are also constructed differently i.e., radial or bias-ply. Radial tires offer better performance and durability denoted by an ‘R’ in their sizes while bias-ply ones indicated with ‘B’, are known for their load carrying capacity and flexibility.

Definition of Upsizing

Upsizing refers to fitting wider, taller or both types compared to stock counterparts thus affecting various areas regarding how a motorcycle performs or handles.

Grip Enhancement : A wide contact patch between road surface and rubber improves traction.

Better Looks : Bigger tyres look more aggressive which many riders prefer.

Increased Stability : Especially at higher speeds larger tires can enhance stability of the motorbike.

Handling : Changing tires improperly may lead to poor handling characteristics.

Speedometer : The speedometer will show incorrect readings if you change its size too much.

Fitment : Some motorcycles cannot accommodate bigger sizes unless modified.

How a Motorcycle Tyre Upsize Calculator Works

This calculator is necessary for determining the right fitment of larger tyres without compromising on performance or safety of your bike.

To use this tool, enter your current tire size and what you are considering. Different measurements will be shown by the calculator which help in understanding the impact that comes with changing sizes.

Important metrics to consider

Overall Diameter : This affects your speedometer and odometer readings because it shows how tall a tyre is in total.

Circumference : It tells you how far one wheel revolution makes your bike travel. A big difference may affect gearing ratios on your motorcycle.

Sidewall Height : Ride quality as well as handling characteristics are affected by this number; comfort might improve with larger sidewalls but precision reduces.

Step-By-Step Guide to Increasing the Size of Your Motorcycle Tires

Let’s go over how you would upsize your tires using a fictional example. Say, for instance, that your current tire size is 120/70-17 and you are considering switching to a 130/70-17.

Step 1: Measure Current Size

Start by writing down your current tire size (120/70-17).

Step 2: Utilize the Upsize Calculator
