It is often difficult to understand the numerous types of ATV tires available in the market because of their numbers and sizes. Nevertheless, this article is here to help you understand how they work so that you can choose the right ones for your vehicle.

What do the Numbers on an ATV Tire Mean?

The fact that ATV tire numbers follow a given format may seem confusing at first glance. However, once this format is understood, it becomes easy to select appropriate tires for one’s quad bike.


In this sequence of figures representing a tire’s size; the initial number stands for its width in inches. Take an instance where there is 25×8-12; hence 25 refers to twenty-five inches wide. A broader tyre surface area improves traction and stability because more ground contact is made with such treads.

Aspect Ratio

The second number shows aspect ratios which are described as heights-to-widths or sidewall heights expressed as a percentage of widths respectively. For example, if we consider 25×8-12 then eight means eight inches tall relative to twenty-five across. It should be noted that shocks absorption abilities among other traits are affected by aspect ratio besides being able to handle different terrains well by a given tyre type.

Rim Diameter

This part tells us about rim diameter measured in inches using Arabic numerals like those used elsewhere within this code system (e.g., first two numbers). Hence third number represents twelve inch rims diameter when talking about 25X8-12 tires size notation. The most important thing here is making sure that whatever dimension you pick fits correctly onto your quad bike’s wheel hub assembly without causing any problems during usage period.

Why Are ATV Tire Numbers Important?

These digits are necessary for selecting proper sizes which will perform as expected while ensuring safety and comfort standards are met. Here’s why you should care about them:


The size of your ATV’s tires affects its performance greatly. The right tire size ensures that the vehicle gets optimum traction, stability and maneuverability on different types of surfaces.


Choosing wrong tire sizes can lead to handling problems or even accidents. Tires with correct dimensions have better grip which helps in reducing rollovers thus enhancing stability as well as safety levels for riders during their off-road adventures.


Another reason why it is important to pick the right tire size for an ATV has got to do with comfortability issues where larger tyres having higher aspect ratios tend to absorb bumps more effectively than smaller ones would hence promoting overall smoothness of rides over rough terrains.

Common Sizes of All-Terrain Vehicle (ATV) Tyres

The following list consists some popular sizes along their usual applications thereby giving you a chance to choose what suits your requirements best considering their descriptions given below:


This particular all-purpose type works well in various conditions characteristic off-road tracks which makes it a favorite choice among many riders looking for versatility when buying new treads.


These aggressive looking sets offer elevated clearance levels besides providing improved grip due greater contact patch area created by wider widths thus making them perfect candidates for use during aggressive riding sessions.


They are designed specifically meant for heavy duty usages such as tackling tough terrains encountered during extreme off road trips therefore if you want something durable enough then this could be perfect selection according its description provided above under common atv tyre sizes section.

How To Select The Right Size Of Off-Road Vehicle Rubber?

There are several factors that one needs to consider before settling on any specific kind of an off-road rubber wheel so as ensure they get value for money spent based on their individual needs and expectations. Here is what you need to know when choosing an ATV tire size:


Different terrains require different tire sizes; wider treads with deeper grooves perform better in muddy areas while narrower ones featuring paddle-like designs excel over sandy surfaces.

ATV Model

Always refer back to your owner’s manual which came along with the purchase of your four-wheel drive regarding recommended tyre sizes because not all rubber wheels can fit onto every machine without causing problems during use or compromising performance levels achieved.

Riding Style

Consider also how aggressive you tend to ride given this may influence what kind of traction control system will work best hence affecting selection between standard or more aggressive treads.

Consequences Of Choosing Wrong Size Of Tyres For Quad Bikes?

Some common effects resulting from incorrect measurements include but are not limited to:

Handling Problems

Wrong dimensions can cause poor maneuverability where oversize wheel rubs against bodywork while undersized one lacks enough grip thus leading into accidents through loss of control over vehicle.


Using inappropriate measurement values may damage suspension parts such as shock absorbers, springs and struts among other components besides spoiling rims or even breaking them altogether thereby necessitating costly repairs alongside decreasing overall performance levels.

How to Upgrade Your ATV Tires

Performance and appearance can be enhanced by changing your ATV tires. These are some things you should think about when doing that.

Advantages of Larger Tires

Taller wheels give more ground clearance and a better grip. They work well on bumpy trails or during off-road expeditions.

Disadvantages of Increased Tire Size

However, big tyres may increase fuel consumption and require suspension modifications. Make sure your vehicle is ready for such an upgrade.

What You Need To Do To Keep Your ATV Tires In Good Condition

Proper maintenance increases the lifespan of your atv tire. Here is what you need to do:

Regular Checks

You should check the tires regularly for signs of wear and tear such as cuts, punctures or uneven tread wear.

Right Inflation Level

Adhere to the recommended pressure so that they can function optimally. Under-inflated or over-inflated ones can affect handling and cause uneven wear.

Tread Depth

Monitor the depth of your treads; if they go bald it means that there will be no enough surface area for gripping especially in wet or muddy conditions.

The Effect Of Tire Size On Performance Of An ATV

Different sizes of wheels have different impacts on how well your all-terrain vehicle performs various tasks. Below are details about this relationship between them;

Acceleration And Speed

When it comes to acceleration, bigger tyres will reduce it while improving top speed on highways etc., smaller ones boost acceleration but limit maximum velocity.

Grip And Balance Stability Control (BSC)

Right size ensures good grip throughout which maintains proper traction even in icy conditions thus preventing skidding-off accidents or rollovers due to loss of control caused by slipping away from designated path areas where friction occurs heavily such as roads covered with gravel stones etcetera

Can I use different tire sizes on my ATV?

Yes, however, be sure that they are suitable for the specifications of your four-wheeler.

How can I take care of my ATV tires?

Take a good look at them from time to time to see if there is any damage or if they need replacing, keep them at the right pressure and check how much tread is left.

What happens if I use the wrong tire size?

Handling may become difficult with wrong-sized tires and this could harm your quad.
