The more you know about your CFMOTO ATV parts, the safer you’ll be when you are operating it. One of the most important components of your ATV is the tires. The tires establish the grip on all surfaces, support the payload, and allow you to travel across rugged terrain.


Below is a brief explanation of ATV loading and inflation rating. If you have any further questions about your tires, feel free to contact a CFMOTO dealer near you.

The Basics of ATV Tires

When you take a look at an ATV tire, there are a series of numbers imprinted on the side of the tread. For example, you may see the number 25×10-12. What do the numbers mean?


●        The first number in this sequence is the height of the tire in inches when it is properly mounted and inflated to the manufacturer’s suggested air pressure.

●        The second number is the width of the tire when it is properly inflated.

●        The third number is the diameter of the inside of the tire in inches as well as a measurement of the diameter of a wheel the tire is meant to be mounted to.


When combined, all of these numbers give you the information you need to understand the ATV loading and tire inflation rating.

Understanding the Rating

It is not uncommon to assume that it’s the tire’s rubber or steel rims that support the weight of the ATV. However, the air pressure inside the tire is what supports the entire payload including the machine, rider, and cargo.


Your tire's load rating tells you the maximum weight capacity that your tire is designed to handle. The higher the tire-load rating, the more weight your tire can handle. However, the tire load rating number is not the actual weight limit. For example, a tire-load rating of 105 means that these tires can handle a maximum weight capacity of up to 2,039 pounds (925 kilograms). In addition, your tire also has a different marker on it that tells you the load rating at a given inflation pressure. The tire's load rating is considered part of the markings on your ATV tire that make up its service description.


The second piece of information that makes up your tire's service description is its speed rating. The speed rating is represented by a letter and tells you the maximum speed at which this tire can go, assuming the car isn't carrying a load that exceeds the tire's load rating. Since the speed rating is a letter (for example, a speed rating of "S" means that the tire can handle a maximum speed of up to 112 miles per hour/180 kilometers per hour), you'll have to check out a chart to learn what speed each of letters indicates.


There are a number of other markings on your ATV tire, including the uniform tire-quality grading (UTQG) system ratings from the U.S. National Highway Traffic Safety Administration; these ratings tell you the tread wear, traction and temperature capabilities of your tires. Some manufacturers' information, such as tire type, width, aspect ratio, construction type, and rim diameter, is also included.


All of this information combined gives you a total reading of your ATV tire loading and inflation rating.
