MTB Tyre Guide


MTB Tyre Guide


As your only contact point with the ground, the right mountain bike tyre can make a huge difference to your performance on the trail. With trail conditions varying in different locations and at different times of the year, choosing the best MTB tyre is not always obvious.


MTB tyres are measured by their width alongside the size of the rim that it is designed to fit. See our tyre size guide to learn more about specific tyre sizing. The conventional wisdom is that wider tyres offer more grip, as they have a more rubber in contact with the ground, while narrower tyres roll quicker as there is less rolling resistance. While this is true for MTB wheel/tyre combinations that have the same diameter, mountain bikes are available with different wheel sizes. A 29er rolls significantly quicker than a bike with smaller 27.5” wheels if they have the same width tyres fitted. This means that we need to think about wheel size as well as tyre size. Our bike wheel size guide explains this in more detail.

Tread pattern makes a huge difference to the performance of a mountain bike tyre. Generally speaking, the smaller and more tightly packed the knobs on the tyre, the faster the tyre will roll but the less grip it will offer. Grip is essential, but the amount you require will vary depending on the specific trail surface you’re riding on. A low-profile tread pattern like that found on the Continental X King will give you plenty of grip on hardpack trails, but you will need the bigger knobs of a more aggressive tyre - like the Maxxis Minion - to find grip on loose surfaces. Tyre choice is always a balance between grip and straight-line speed, and the best tyre tread pattern will be different for different riding styles as well as different trail conditions.

MTB tyre tread

An important consideration for UK riders, particularly if you like to ride natural trails, is how well the tyre can clear mud. If your tyre clogs up with mud easily you will lose grip more often, so dedicated mud tyres - like the Specialized Storm Control or Maxxis Shorty - have spike-like knobs with wide gaps between them to stop mud clinging to the tyre.

MTB tyre tread

While choosing a tyre for specific conditions is essential for racers, most mountain bike trail riders don’t want the hassle of changing their tyres before every ride. This is where a good all-rounder comes in. A tyre with a relatively open tread pattern, reasonably sized mid-tread and aggressive side knobs - like the Maxxis High Roller - offers the ideal balance between grip and rolling resistance without clogging up with mud in the wet.


The rubber on your tyres gives you grip by conforming to the lumps and bumps of the surface you are riding on. This means that a softer rubber compound will offer more grip than a harder compound. For the same reasons, a soft compound will be slower rolling than a hard compound. As with most things mountain bike related, there is always a compromise between speed and grip, so the ideal tyre compound will vary depending on the type of terrain you ride on. Soft compounds are preferable for downhill racing while harder compounds are a better choice for long distance cross-country rides.

Another thing to consider is durability. Soft rubber compounds wear considerably quicker than hard rubber compounds, especially in the centre of the tyre as it spends most time in contact with the ground. To take account of this, some premium tyres are made from multiple compounds, with harder compounds in the centre for improved durability and speed, and softer compounds on the side for improved cornering grip.


Mountain bike tyres need to be tough enough to cope with hard riding on challenging terrain. For this reason, mountain bike tyres are tougher than road tyres. Unfortunately making a tyre tough also makes it heavy. There is always a trade-off between weight and toughness. Cross-country race tyres are the lightest but are not recommended for anything other than racing due to a lack of durability. Downhill tyres are the toughest, with double thickness sidewalls to reduce the chance of getting a flat when the tyre pinches against the rim. These tyres are too heavy for efficient trail riding however.

In order to improve durability without adding too much weight, tyre manufacturers add tough abrasion resistant layers to their high-end tyres. Side walls are particularly vulnerable to cuts from rocks. Premium MTB trail tyres feature sidewalls reinforced with a lightweight abrasion resistant layer that protects the sidewalls of the tyres from cuts. Look for Specialized GRID, Schwalbe Evo, Continental Apex or Maxxis Exo tyres for the best side wall protection.


With their vastly improved puncture resistance, Tubeless tyres are fast becoming the norm on mountain bikes. When used with tubeless tyre sealant, small punctures will seal themselves without you noticing. Even larger punctures are easy to fix on the trail, as you don’t even need to take the wheel off the bike. See our tubeless repair video to learn how to repair a tubeless MTB tyre

Another advantage of tubeless tyres is that you can reliably run lower tyre pressures. This gives you more grip without the pinch puncture risk you get with inner tubes. While they take a little more effort to set up initially, this extra work is more than offset when you realise that punctures are almost a thing of the past. Converting to tubeless tyres is easy. Tubeless compatible tyres are often labelled ‘Tubeless Ready’.


Alongside wheel weight, tyre weight is probably the most important weight consideration on a bicycle. This is because of the rotational effect of the wheel which means that adding weight to the rim will slow you down more than adding weight anywhere else. You will notice the effect of a heavy tyre most climbing and accelerating, so is the first place to look when you want to make your bike lighter. The easiest way to reduce tyre weight without compromising performance is to choose a tyre with a folding bead. Folding tyres use a Kevlar bead instead of a traditional steel bead which is just as strong, but much lighter.

Tyre Pressure

One of the simplest ways to improve the performance of your mountain bike is to ride with the right tyre pressure. The ideal tyre pressure will vary depending on riding style, rider weight, and trail surface. You want your tyres to be soft enough to conform to the lumps and bumps on the trail, but not so soft that you bang your rims on rocks and roots, or the tyre folds over and squirms about while cornering.

If you are riding cross country trails or a trail centre loop, then you will want your tyre to be hard enough for efficient rolling on the climbs but not so hard that you loose grip on the downhills. For aggressive downhill riding lower pressures are ideal as they will give you more grip. Downhill tyres tend to have thicker reinforced side walls that help to prevent pinch punctures and give you additional support while cornering. Another consideration is that a higher-volume tyre will require less pressure than a thinner tyre for optimal performance.

There are too many variables to give an ideal pressure range here, but most mountain bikers will run between 20psi and 40psi. Lighter riders will benefit from lower tyre pressures, while heavier bikers will need higher pressures to get the right level of support from the tyre. Mountain bikers tend to run a couple of psi more in the back than the front, as it is the rear tyre that takes the biggest hammering. A simple rule of thumb is never to exceed the recommended tyre pressure, found on the tyre side wall, but don’t be afraid to experiment with lower tyre pressures, especially if you are running a tubeless set-up.

Winter Tyres

The main difference between riding off-road in winter compared to summer is that the trails don’t get much time to dry out. While we sometimes get muddy trails in summer, we’ll definitely have muddy trails in winter, probably all winter. This means it’s worth putting on tyres that can cope with mud as the days get shorter. Of course, if you only ride armoured trail centre trails then you can use the same tyres all year round, but part of the attraction of winter MTB riding is the fun you can have sliding around on muddy trails.

Tread Pattern

Tread pattern is key. A spiked tread is the best for muddy conditions as the long, well-spaced knobs can penetrate the mud to find grip beneath without clogging up. Of course, you are unlikely to ride through mud all the time, so unless you’re DH racing, you’ll want a tyre that still works on rocky and hardpack trails. This is where the intermediate or cut-spike tyre comes in. These have wide spaced blocky knobs that can penetrate mud and don’t clog up while still offering good support on hard surfaces. The Specialized Hillbilly and Maxxis Shorty are great examples.

Tubeless tyres offer a great advantage in soft winter conditions as you can run lower tyre pressures without risking pinch flats. Lower tyre pressures offer more grip, especially in wet and muddy conditions, as the tyre can conform to the ground more easily to find grip. Many experienced MTB riders will lower their tyres pressure when riding muddy tracks. To avoid bashing your wheel rim on rocks you can use tyre inserts like CushCore to cushion the tyre against impacts.

Front & Rear?

The problem with mud tyres is that they roll less quickly, so many riders compromise with a front/rear split. Many MTB riders will fit a winter tyre on the front and leave a regular tyre on the rear. This way you get extra grip on the front wheel, where you need it most for control. The rear tyre effects rolling resistance more than the front so keeping your rear summer tyre on is a good compromise. As long as you’ve got control of the front end, sliding about in the mud is a lot of fun.
