Quick answer: choose mountain bike tyres in this order: the correct size for your wheels, a tread suited to your terrain, a width that fits your rims and frame, and a casing strong enough for your riding. For most trail riders, a 2.3–2.4 inch tubeless-ready tyre with a medium-soft compound and a medium-weight casing is the best all-rounder. Use a grippier tyre up front and a faster-rolling tyre at the rear.

1. Size: match your wheel
The wheel diameter must match: 26, 27.5 (650b) or 29 inch. The ISO/ETRTO number on the sidewall (for example 60-622 for 29 × 2.35) is the reliable reference: 559 = 26 in, 584 = 27.5 in, 622 = 29 in.
2. Tread: match your terrain
| Tread | Best for |
|---|---|
| Low, closely spaced knobs | XC, hardpack, gravel, fast rolling |
| Medium knobs, strong shoulders | All-round trail riding |
| Tall, open knobs | Loose, soft ground, mud and enduro |
| Spike / mud tread | Deep mud and winter riding |
3. Width: match rims and frame
| Discipline | Typical width | Rim internal width |
|---|---|---|
| XC | 2.2–2.4 in | 23–27 mm |
| Trail | 2.3–2.5 in | 27–30 mm |
| Enduro / DH | 2.4–2.6 in | 28–35 mm |
| Plus | 2.6–3.0 in | 35–45 mm |
Check frame and fork clearance before going wider. Leave at least 5–6 mm clearance for mud.
4. Casing: match your riding
Light casings roll faster and feel lively but cut and pinch-flat more easily. Reinforced casings (Maxxis EXO+, DoubleDown; Schwalbe Super Trail, Super Gravity; Continental Trail, Enduro) are heavier but support lower pressures and resist damage. Most trail riders are happiest with a mid-weight reinforced casing, especially on the rear.
5. Compound
Softer rubber grips better and wears faster. Many tyres come in two or three compounds; choose the softest for the front if you ride rocks and roots, and a longer-lasting compound for the rear.
Tubes or tubeless?
Tubeless is now the standard for mountain biking. It lets you run lower pressure for grip and comfort, and sealant fixes most small punctures automatically. You need tubeless-ready rims, rim tape, valves and sealant. Tubes are cheaper and simpler but more prone to pinch flats.

Budget tyres for casual riding
Basic wire-bead tyres such as the CST Eiger are cheap and fine for paths and gentle riding on entry-level bikes. They are heavier and less grippy than folding, tubeless-ready tyres, so riders on real trails will notice the upgrade.
Frequently asked questions
How often should I replace mountain bike tyres?
When knobs are worn round or torn, the casing is cut, or grip noticeably drops. Rear tyres usually wear two to three times faster than fronts.
Can I use different tyres front and rear?
Yes, and most riders do: a grippier front and a faster-rolling rear.
Are expensive tyres worth it?
Tyres are one of the most noticeable upgrades. A quality tyre improves grip, comfort and speed more than many pricier parts.
