The best dirt bike tires for trail riding match your terrain, the motorcycle’s approved fitment, and any public-road sections on the route. For mixed enduro riding, the Michelin Enduro Medium 2 is a useful starting point to compare. For intermediate terrain without road use, look at the Michelin StarCross 6 Medium Hard. Pirelli’s Scorpion XC Mid Soft targets softer cross-country conditions, while the MT 21 Rallycross is the on/off-road option in this shortlist.
Those are use-case starting points based on manufacturer descriptions. They are not a universal fit recommendation, and we have not ridden these tires back-to-back.
Research checked October 4, 2026. Product descriptions and example sizes come from the linked manufacturers. Sizes, versions, approval markings, and local availability must be checked for the exact tire you buy.
Four trail tire options compared
| Tire family | Reason to compare it | Example listed sizes | Road-use check |
|---|---|---|---|
| Michelin Enduro Medium 2 | Enduro riding across varied terrain | Front 90/90-21 or 90/100-21; rear 120/90-18 or 140/80-18 | Confirm approval of the exact tire and fitted system |
| Michelin StarCross 6 Medium Hard | Intermediate-terrain off-road riding | Front 80/100-21 or 90/100-21; rear examples include 110/100-18 and 110/90-19 | Michelin labels it not street legal |
| Pirelli Scorpion XC Mid Soft | Soft-to-medium cross-country terrain | Front 80/100-21; rear examples include 110/100-18 and 120/100-18 | NHS versions are not for public-road use |
| Pirelli MT 21 Rallycross | Dirt and gravel routes that also include pavement | Front 80/90-21 or 90/90-21; rear examples include 120/90-17 and 120/90-18 | On/off-road family; verify the actual size, markings, and local requirements |
These sizes are examples of products in the manufacturers’ ranges, not interchangeable options for your motorcycle. Michelin’s tire compatibility tables document the Michelin size examples; Pirelli lists its sizes on the linked product pages. A tire being available in an 18-inch size does not mean that every 18-inch rear wheel can use it.
Which family belongs on your shortlist?
Michelin Enduro Medium 2 for varied enduro terrain
Michelin presents the Enduro Medium 2 as a tire for varied enduro conditions. That makes it a practical first comparison when a ride does not stay on one predictable surface.
Why consider it: its stated use is directly relevant to enduro riding, and Michelin documents both front and rear sizes. Limits: we do not have independent wear or grip measurements, and the family name alone does not establish the road legality of your complete setup. Confirm the exact version with the supplier.
Michelin StarCross 6 Medium Hard for intermediate terrain
The StarCross 6 Medium Hard is positioned by Michelin for intermediate terrain. Despite the name, it should not be treated as a blanket recommendation for every hard, rocky, or wet trail.
Why consider it: it is a terrain-specific off-road alternative when its size and intended use match your bike and route. Limits: Michelin explicitly labels it not street legal. A registration plate on the bike does not change that tire restriction.
Pirelli Scorpion XC Mid Soft for softer cross-country conditions
Pirelli describes the Scorpion XC Mid Soft as a cross-country tire for soft-to-medium surfaces. It is the most directly soft-terrain-focused option in this four-family comparison.
Why consider it: its intended surface category is clear. Limits: road approval must be checked by exact size and version. For example, Pirelli’s 120/100-18 rear listing is marked NHS. That version must not be used on public roads.
Pirelli MT 21 Rallycross for trail rides with road sections
Pirelli positions the MT 21 Rallycross for on/off-road use, including dirt tracks, gravel, and asphalt travel. It is the logical family to investigate first among these four if your route includes public-road connectors.
Why consider it: the intended use includes pavement, rather than assuming a competition tire can cover the trip to the trail. Limits: confirm the exact tire’s approval and the motorcycle’s required fitment. This guide does not establish wet-road braking performance or promise a particular service life.
Choose by the whole ride
Write down the surfaces you ride most often and the conditions that cause the most difficulty. “Trail riding” could mean damp soil, deep loose ground, dry intermediate dirt, exposed rock, or gravel roads. A manufacturer’s terrain category is a useful filter; it is not a guarantee of grip on every surface within a trail network.
- Mostly varied enduro trails: begin with a broadly positioned enduro family, then narrow by approved size and the conditions that matter most.
- Mostly one soil type: compare the maker’s terrain-specific options rather than buying solely on knob appearance.
- Any public-road sections: filter for an appropriately approved road-capable tire and complete wheel setup before comparing off-road features.
- Regular changes in terrain: explain the full route to a tire specialist. Avoid optimizing the purchase for only one short section.
Our shortlist is selective, not a claim to cover every suitable brand or riding discipline. Technical hard-enduro, trials, motocross racing, and long-distance dual-sport touring can require a different comparison.
Confirm fitment before buying
Use the motorcycle handbook and an approved fitment guide as the starting point. Michelin’s motorcycle tire FAQ recommends retaining the specified dimensions unless the vehicle manufacturer validates an alternative.
Have a qualified motorcycle tire professional confirm:
- The approved front and rear dimensions, wheel diameters, and permitted rim widths.
- Correct front/rear designation, construction, and required load and speed ratings.
- Compatibility with the actual rim and its tube-type or tubeless requirements.
- Any tube or mousse product’s exact compatibility and use restrictions.
- Clearance on the motorcycle and the suitability of the complete front/rear combination.
Michelin’s professional tire guide emphasizes correct size selection and clearance verification. A wider tire is not automatically an improvement, and a nominal size match does not resolve every fitment requirement.
Road markings and tire systems matter
NHS means Not for Highway Service. Pirelli states that its NHS motorcycle tires cannot be used on public roads. Check the exact sidewall and part listing rather than relying on a family name, another rider’s experience, or a marketplace description.
The internal tire system matters too. Michelin states that Bib Mousse is for off-road use and is not street legal. A road-capable tire does not make every mousse-equipped setup road-capable.
Get mounting and tire-system selection handled by a qualified professional. Follow the motorcycle and tire manufacturers’ applicable pressure guidance for the actual setup; this article does not prescribe a universal trail pressure. Pirelli’s tire FAQ points riders to the motorcycle manufacturer’s recommendations.
Compare cost without guessing tire life
Ask for a quote for the correct size and version, including mounting and any required tube, valve, or other approved service items. Compare equivalent quotes. A tire-only listing and an installed pair are different purchases.
We have not assigned mileage, hour-life, grip scores, or “best value” ratings. Those would require comparable evidence for the riding conditions, motorcycle, and tire system. Confirm local availability and return conditions before ordering, especially if a tire has to be specially sourced.
Frequently asked questions
What are the best dirt bike tires for a beginner on trails?
Start with a manufacturer-approved fitment suited to the terrain and any road use. A broad enduro category can be a useful comparison point, but rider experience does not make one tire model suitable for every motorcycle.
Can I use motocross tires for trail riding?
Some off-road tires may match the terrain and approved motorcycle fitment, but the exact product must be checked. A competition tire labeled not street legal is unsuitable for public-road links between trails.
Can I mix different front and rear tires?
Do not assume any two tires of the right size are an approved pair. Michelin’s safety guidance recommends matching front and rear tires from the same product line. Obtain manufacturer-backed advice before departing from the recommended combination.
Does soft terrain mean a soft rubber compound?
Do not infer compound properties from the terrain name alone. Treat the name as the manufacturer’s intended-surface category, and use its technical information to establish compound and construction details.
Can I substitute an 18-inch rear tire for a 19-inch one?
No. The tire’s bead-seat diameter must match the wheel. This article’s 18- and 19-inch examples illustrate separate catalog options, not interchangeable replacements.
