Off-road and motocross tyres are the only contact patch between your dirt bike and loose terrain. This range covers front and rear knobbies from Pirelli, Michelin and Eurogrip, built for sand, mud, intermediate and hardpack tracks across 18, 19 and 21 inch rims. Match compound to soil and ride harder every lap.

Choosing an off-road tyre starts with terrain, not brand. Soft compounds clear mud and bite into sand, while harder compounds last longer on rocky hardpack. Knob height and spacing decide how the tyre digs in versus how it sheds debris.
| Terrain | Compound | Front size | Rear size | Best for |
|---|---|---|---|---|
| Soft / sand | Soft | 90/100-21 | 110/90-19 | Loose, deep dirt |
| Intermediate | Mid soft | 80/100-21 | 120/90-19 | Mixed loam tracks |
| Hardpack | Hard | 80/100-21 | 110/100-18 | Rocky, dry trails |
| Enduro / trail | Multi | 4.00-18 | 130/80-17 | Trail and road link |
Front and rear are never interchangeable. The front, often a 21 inch carcass, steers and tracks ruts, while the rear, typically 18 or 19 inch, puts power down. The Pirelli Scorpion MX32 in 90/100-21 57M runs a soft directional tread for traction, and the MT43 Professional 4.00-18 64P suits trail and enduro use. Check the load and speed code, such as 62M or 65T, against your bike weight.
Tube type construction means you fit a matching tube and rim tape. Run lower pressures, around 12 to 15 psi, on soft terrain for a bigger footprint, and raise toward 15 to 18 psi on hardpack to protect the carcass. NHS markings confirm a non highway speed tyre built for competition, not sealed roads. A 130/80-17 rear and a 110/90-19 cover different bike classes, so confirm rim diameter before you buy.
Frequently asked questions
What is the difference between a front and rear MX tyre?
Front tyres, usually 21 inch, steer the bike and track ruts with a directional tread. Rear tyres, typically 18 or 19 inch, lay down power with taller, wider knobs. They are not interchangeable, so always fit the size and pattern made for each axle.
How do I pick a compound for my local track?
Match compound to soil. Soft compounds bite into sand and clear mud, mid soft suits mixed loam, and hard compounds last on rocky hardpack. Pirelli, Michelin and Eurogrip in this range cover soft through hard, so choose by the terrain you ride most.
Do off-road tyres need tubes?
Most knobby off-road tyres are tube type and need a matching tube plus rim tape to seal the spoke nipples. Fit a tube rated for your tyre size and run lower pressures around 12 to 15 psi on soft ground for grip.
