How Important are Off-Road Tires for Your Bike?

A man rides a bike with off-road tires down a mountainside.

Just like there are many different kinds of shoes, there are also many different kinds of tires for your bike. Each type of tire has its own function that makes them better for different kinds of biking conditions. If you are considering taking your bike off the paved roads and hitting the trails, you might be wondering what kind of tires you need. Will your regular skinny tires be enough? How important are off-road tires for your bike?

What are off-road tires?

Off-road bike tires are optimized for riding on soft surfaces rather than on a normal paved road or path. They have a deep, wide tread that gives the rider more traction on loose dirt, sand, gravel, mud, or other unpaved surfaces. 

Off-road bike tires are typically between one and three inches thick. That means they are thicker than regular road tires (also known as skinny tires). They typically have a PSI between 25 and 50, which is significantly lower than skinny tires. The lower PSI allows the tire to better grip and conform to the terrain, resulting in better traction. 

If you like to ride your bicycle on unpaved surfaces more than on paved roads or trails, having off-road tires is very important. They will give your bike more traction on loose surfaces, reducing your risk of slipping and sliding. Having additional traction will help prevent you from getting into accidents, keeping you safe and reducing the risk of sustaining injuries while biking off-road. 

How important are off-road tires for your bike?

There are many aspects of your bike that are important for off-road biking. Choosing a bike depending on its weight, size, and other factors may be important for optimizing your riding experience on off-road terrain. However, many people overlook the critical importance of off-road tires. So, how important are off-road tires for your bike?

Using thinner tires on rough terrain can be incredibly dangerous. Choosing the right off-road tires is a matter of safety. The increased traction they provide can be critical to providing you with more stability and reducing your risk of crashing. There are many different kinds of off-road tires, but here are a few factors to take into consideration. 

Tire Width

Off-road tires come in several different widths. You should select the width of your tire depending on the type of off-road terrain you intend to bike on. The wider your tire, the more traction and stability you will have. 

For example, if you plan to bike on rough trails, consider a tire width of 2.25 to 2.6 inches. For biking downhill, consider a tire width of 2.4 to 2.5 inches. If you are planning to bike cross-country, thinner 1.9 to 2.25 inch tires should be plenty because cross-country biking is comparatively smoother and flatter. 

Tire Size

Keep in mind that the bigger your tire diameter, the more ground you will be able to cover in a given amount of time. Tire size is one factor that impacts your speed on a bike. The most common bike tire sizes are 26, 27.5, and 29. 


Bike tires are made of unique rubber compounds that vary in how firm they are. Companies measure the firmness of their tires by their durometer. If a bike tire has a lower durometer, often below 60, it is a softer bike tire. Softer tires typically have a better grip on the surface, but can be slower and wear out more quickly.  

Conversely, tires with a higher durometer, more than 60, are very firm and more resistant to the surface they are on. They may roll faster and last longer, but they will have much less traction than tires with lower durometers.
