The tires of your ATV play a crucial role when it comes to performance. With the right set of tires, you can expect a drastic improvement in handling, traction, and overall experience of riding an ATV.
Understanding how to read ATV tire size chart, how to measure your current tires, and what information is included in a typical tire size designation is important. With this knowledge, you will be able to make better decisions when it comes to selecting new tires for your vehicle.
How Does Tire Size Affect Your ATV’s Performance?
ATV’s performance and safety are highly dependent on its tire size. Tire size affects the way an ATV handles, accelerates, and brakes. It also determines the exact weight that your ATV can safely carry.
Factors such as tire diameter, load index, tread width, and off-road capabilities should all be taken into consideration when selecting tires for your ATV. Different sizes of off-road tires provide different levels of traction on various terrain and surfaces.
Changing tire size can also affect the overall speed of the ATV, as well as its handling and turning ability. It is important to understand how tire size affects your ATV’s performance so you can choose tires that provide the best results for your needs.
Different Types of ATV Tires & Sizes

Radial vs bias ply tires is among the most common choices when it comes to all-terrain vehicle tire sizes, while light truck tire size comparison can help you decide which option will work best for your vehicle.
ATV tires come in a variety of sizes, with each size having its own set of characteristics and benefits. It’s also important to understand how light truck tires compare to ATV tires in terms of size and performance.
Radial Tires vs Bias Ply Tires
Radial tires have the cords (or plies) of the tire running at 90 degrees to the centerline of the tire, while bias ply tires have the cords running at an angle to the centerline. They tend to offer better handling and a smoother ride than bias-ply tires, but they are also typically more expensive.
Bias ply tires, on the other hand, are generally less expensive and more durable than radial tires, but they may not provide as good of ride quality. Consider the basic needs of your ATV while you are selecting between the two options.

Reading and Interpreting The ATV Tire’s Sidewall Markings
ATV tires are marked with both metric and alphanumeric codes to help you understand the characteristics of the tire, such as its width, height, speed rating, load index, and more.
By understanding the sidewall markings on an ATV tire you will be able to determine the correct size and type of tire that you need.
The sidewall markings are typically made up of two parts: a metric code and an alpha-numeric code. The metric code is usually expressed in millimeters, while the alpha-numeric code will provide information about the tire’s tread pattern, load capacity, speed rating, etc.
Steps to Read & Understand
The sidewall of an ATV tire is typically marked with various codes and numbers that provide important information about the tire. Let’s discuss the most common markings labeled on ATV tire sidewalls.
- Tire Size: The tire size is typically marked in a string of numbers and letters at the beginning of the sidewall markings. For example, a tire size of “27×9-14” would indicate a tire that is 27 inches in diameter, 9 inches wide, and fits a 14-inch wheel.
- Load Rating: Mostly 2- or 3-digit number, it indicates the maximum weight that it can safely carry. It’s often followed by the letter “L” (ex. “45L”).
- Speed Rating: You get to know the maximum speed at which the tire can be safely used.
- Treadwear, Traction, and Temperature: These are three-digit numbers followed by the letters TW, TR, and TT respectively. They indicate how well the tire will wear, how well it will grip the road, and how well it will handle the heat.
- M+S or M/S or M&S: M means mud while S is for snow. It’s easy to understand with these markings about the kind of road conditions the tire is made for.
- DOT: This stands for the Department of Transportation, and indicates that the tire meets the minimum safety standards set by the DOT. 4 digits that you see at the end mean the week and year this tire was manufactured.
Common Pitfalls and Mistakes when Choosing Tires for Your ATV

- Not considering the type of terrain the ATV will be used on: Tires designed for mud or sand will not perform well on hard-packed dirt or pavement.
- Not checking the tire size: The size of the tire must match the size recommended by the ATV manufacturer to ensure proper fit and performance.
- Not checking the load capacity: Tires must be able to handle the weight of the ATV and any cargo or passengers.
- Not considering the tread pattern: Different tread patterns are designed for different types of terrain, such as mud, rocks, or snow.
- Not checking for quality: Cheap or low-quality tires may not last as long or perform as well as higher-quality tires.
- Not considering if the tire is tubeless or tube-type: This can affect how the tire is mounted on the ATV.
- Not considering the age of the tire: Tires degrade over time, even if they have not been used, so it is important to check the age of the tire before purchasing it.
- Not checking for certification: Tires should have a DOT certification, which indicates that the tire meets federal safety standards.
Concluding Remarks
The correct tire size for an ATV is important for several reasons. Properly sized tires can help to improve handling, traction, and stability, which can in turn help to reduce the risk of accidents and injuries.
Additionally, the correct tire size can help to improve the overall performance of the ATV, allowing it to reach its full potential in terms of speed, power, and maneuverability. In conclusion, it is essential to select the right tire size for an ATV to ensure maximum safety, performance, and enjoyment while riding.
