If you’re an avid cyclist, you’ve probably wondered at some point whether it’s possible to put road tires on a mountain bike. After all, road tires are designed for smooth pavement and high-speed riding, while mountain bike tires are built for off-road trails and rugged terrain. So, can you mix and match?
The short answer is yes, you can put road tires on a mountain bike. However, before you rush out to make the switch, there are a few important factors to consider, like the size of your wheels and rims, the width of your forks and frame, the type of your brakes, etc.
In the following contents, we will explore all details about them and more to make sure that you can easily and successfully put road tires on your mountain bicycle.
Let’s start from figuring out the differences between road tires and mountain bike tires.
What Are Differences Between Road Tires and Mountain Bike Tires
Road tires and mountain bike tires are different in many aspects, which can significantly impact your riding experience.
Shape: Round and Smooth vs. Flat and Knobby
One of the first things you’ll notice about road tires is their round and smooth shape. This design allows for minimal rolling resistance, making them ideal for smooth surfaces like asphalt and concrete. On the other hand, mountain bike tires have a flatter profile with knobbier treads. These knobs provide extra traction and grip, allowing riders to navigate rough and uneven terrains more effectively. So, if you’re planning to hit the trails or explore off-road routes, mountain bike tires are your best bet.
Size: Narrow and Small vs. Wide and Large
Road tires are known for their narrower width and smaller diameter compared to mountain bike tires. The smaller size of road tires reduces both weight and drag, making them more efficient on paved roads. Additionally, the narrow profile helps to reduce rolling resistance, allowing you to maintain higher speeds with less effort. On the other hand, mountain bike tires are wider and larger, providing stability and better shock absorption on rough terrains. The increased surface area of mountain bike tires also enhances traction, ensuring you stay in control, even on loose or slippery surfaces.
Tread: Minimal vs. Knobby
When it comes to tread patterns, road tires generally have a smoother or even slick surface. This design maximizes contact with the road, enhancing grip and minimizing rolling resistance. On the other hand, mountain bike tires feature more aggressive tread patterns, with larger and deeper knobs. These knobs are designed to dig into the ground, providing better traction and stability on off-road trails. The tread pattern of mountain bike tires is crucial for navigating challenging terrains like mud, gravel, and rocks.
Pressure: High vs. Low
Another key difference between road tires and mountain bike tires is the recommended air pressure. Road tires typically require higher air pressure, often ranging from 80 to 130 psi (pounds per square inch). The high pressure helps to reduce rolling resistance and improve efficiency on smooth surfaces. Mountain bike tires, on the other hand, are usually run at lower air pressure, typically between 30 to 50 psi. The lower pressure allows for increased shock absorption and better traction on uneven and bumpy terrains.
Material: Harder vs. Softer Rubber
Road tires are typically made of harder and thinner rubber compounds. This choice of material enhances durability and reduces rolling resistance on smooth surfaces. However, the harder rubber may be more prone to slipping on loose surfaces and can be less forgiving on rough terrains. In contrast, mountain bike tires are made of softer and thicker rubber compounds. The softer rubber provides better grip on off-road trails and helps absorb shocks from bumps and obstacles, enhancing overall comfort and control.
Why Put Road Tires on a Mountain Bike

Now, let’s get into the step-by-step process of installing road tires on your mountain bike:
Step 1: Remove the old tires
Start by flipping your bike over and removing the wheels. If you have quick-release skewers, simply open them to release the wheels. If you have thru-axles, use the appropriate tool to loosen and remove them. Once the wheels are off, use tire levers to gently pry the old tires off the rims. Start at one side of the tire bead and work your way around until the tire comes off.
Step 2: Check the condition of your rims and spokes
While your old tires are off, take a moment to inspect the condition of your rims and spokes. Look for any damage, such as cracks, dents, or loose spokes. If you notice any issues, it’s best to address them before installing the new road tires.
Step 3: Check the direction of rotation
Road tires often have a specific direction of rotation indicated by arrows on the sidewall. Make sure to align the tires with the wheels accordingly. This ensures optimal performance and grip when riding.
Step 4: Install the new tires
Starting at the valve hole, insert one bead of the tire into the rim. Use your hands or tire levers to work the bead around the rim until it’s fully seated. Be careful not to pinch the inner tube during this process. Once one bead is in place, slightly inflate the tire to give it some shape. Then, insert the other bead into the rim, again starting at the valve hole and working your way around. Use your hands or tire levers as needed to fully seat the bead.
Step 5: Inflate the tires
Now that both beads are in place, it’s time to inflate the tires to the recommended pressure. The recommended pressure can usually be found on the sidewall of the tire. Use your pump to gradually inflate the tires, making sure they reach the desired pressure. Be cautious not to over-inflate the tires, as this can cause them to blow off the rim or result in a harsh ride.
Step 6: Check for bulges or gaps
After inflating the tires, carefully inspect them for any bulges or gaps. These can indicate that the beads are not properly seated or that the inner tube is pinched. If you notice any issues, deflate the tire and reseat the beads before reinflating.
Step 7: Mount the wheels back on your bike
With your new road tires installed and properly inflated, it’s time to mount the wheels back on your mountain bike. Align the wheel with the dropouts and tighten the quick-release skewer or thru-axle securely. Give the wheel a spin to ensure it rotates smoothly and doesn’t rub against the brake pads.
And there you have it! You’ve successfully put road tires on your mountain bike. Now you’re ready to hit the road and enjoy the speed and efficiency that road tires offer. Just remember to adjust your riding style and be cautious when taking corners or riding on uneven surfaces, as road tires are designed for smooth pavement.
