Why Measure Motorcycle Tires?
Knowing your motorcycle tire size allows you to:
- Select the right replacement tires when it’s time for a new set.
- Check if your tires are properly inflated.
- Maintain your motorcycle’s handling and stability.
- Prevent potential damage to your motorcycle.
Understanding Tire Size Codes
Motorcycle tire sizes are indicated by a unique code that provides valuable information about the tire’s dimensions and construction. This code, typically found on the sidewall of the tire, consists of a series of numbers and letters. We’ll explore the meaning of these codes and guide you through the process of accurately measuring your motorcycle tires.
How To Measure Motorcycle Tires
Maintaining your motorcycle’s tires is crucial for safe and enjoyable riding. Proper tire pressure and tread depth are essential for handling, braking, and overall performance. Knowing how to measure your motorcycle tires accurately is a fundamental skill every rider should possess. This guide will walk you through the process, providing you with the knowledge and tools to ensure your tires are in optimal condition.
Understanding Tire Sizing
Motorcycle tires have a unique sizing system that provides valuable information about their dimensions and specifications. Deciphering this code is the first step in measuring your tires correctly.
Decoding the Tire Size Code
A typical motorcycle tire size code looks like this: 120/70-17. Let’s break down each component: (See Also: What Size Tires Will Fit My Car)
- 120: This number represents the tire’s width in millimeters, measured from sidewall to sidewall.
- 70: This is the aspect ratio, expressed as a percentage. It indicates the ratio of the tire’s height to its width. In this case, 70% of 120mm is the tire’s height.
- 17: This number denotes the tire’s rim diameter in inches.
Additional Information
You might also find additional markings on your tire, such as:
- Load Index: This number indicates the maximum weight the tire can safely carry.
- Speed Rating: This letter represents the maximum speed at which the tire is designed to operate.
Measuring Tire Width
To measure the tire width, you’ll need a flexible measuring tape.
Steps:
- Park your motorcycle on a level surface and ensure the tires are cold.
- Locate the widest point of the tire, usually near the center.
- Wrap the measuring tape around the tire at this point, ensuring it’s snug but not stretched.
- Read the measurement in millimeters.
Measuring Tire Height
Measuring tire height is straightforward.
Steps:
- Park your motorcycle on a level surface and ensure the tires are cold.
- Locate the tallest point of the tire, which is usually the center of the tread.
- Use a measuring tape to measure the vertical distance from the ground to the top of the tire.
Measuring Tread Depth
Tread depth is crucial for tire grip and safety.
Tools Needed:
- Tire tread depth gauge
Steps:
- Park your motorcycle on a level surface and ensure the tires are cold.
- Insert the tread depth gauge into the grooves of the tire tread.
- Read the measurement in millimeters or inches.
A general rule of thumb is that tires should have at least 1.6mm (0.06 inches) of tread depth remaining. (See Also: Do Bald Tires Make Your Car Shake)
Checking Tire Pressure
Proper tire pressure is essential for optimal performance and safety.
Tools Needed:
- Tire pressure gauge
Steps:
- Park your motorcycle on a level surface and ensure the tires are cold.
- Remove the valve cap from the tire valve.
- Press the tire pressure gauge firmly onto the valve stem.
- Read the pressure displayed on the gauge.
- Compare the reading to the recommended pressure listed in your motorcycle’s owner’s manual or on a sticker located on the swingarm.
- Adjust the pressure as needed using an air compressor or a tire pressure deflation tool.
Key Points to Remember
- Always measure your motorcycle tires when they are cold.
- Use a reliable measuring tape and tire pressure gauge.
- Consult your motorcycle’s owner’s manual for recommended tire pressure.
- Regularly check your tire tread depth and replace tires when necessary.
- Maintain proper tire inflation to ensure optimal handling, braking, and fuel efficiency.
Recap
Measuring your motorcycle tires is a fundamental skill that every rider should master. By understanding tire sizing, using the correct tools, and following the steps outlined in this guide, you can ensure your tires are in optimal condition for safe and enjoyable riding. Remember to check your tire pressure, tread depth, and width regularly to maintain peak performance and safety.
Frequently Asked Questions About Measuring Motorcycle Tires
What is the standard way to measure motorcycle tires?
Motorcycle tire sizes are indicated by a series of numbers and letters. The most common format is “front tire size” followed by “rear tire size”. For example, a motorcycle might have a tire size of “120/70-17” on the front and “160/60-17” on the rear.
What do the numbers and letters in a motorcycle tire size mean?
The numbers and letters represent different aspects of the tire’s dimensions and construction. The first number indicates the tire’s width in millimeters. The second number represents the aspect ratio, which is the ratio of the tire’s height to its width. The last number is the wheel diameter in inches.
How do I measure the tread depth of my motorcycle tires?
You can use a tire depth gauge to measure the tread depth. Insert the gauge into the grooves of the tire tread and read the measurement. The minimum tread depth recommended for motorcycle tires is 2/32 of an inch. (See Also: Does Walmart Mount Tires)
What happens if my motorcycle tires are worn out?
Worn-out motorcycle tires can be dangerous. They have reduced grip, which can lead to loss of control, especially in wet or slippery conditions. It’s important to replace your tires when the tread depth reaches the minimum recommended level.
Can I use car tires on my motorcycle?
No, you should never use car tires on your motorcycle. Motorcycle tires are designed specifically for the unique demands of motorcycle riding, such as cornering forces and weight distribution. Using car tires on a motorcycle can be extremely dangerous.
