Front 80/100x21 & Rear 100/100x18 Dirt Bike Tire Set

Our review of this front 80/100x21 and rear 100/100x18 tire set finds it best for trail and motocross riders who need reliable grip on loose and mixed surfaces; the single biggest reason to buy is the aggressive deep tread and soft-to-intermediate rubber that consistently improves traction and braking on sand, loam, and hard-packed dirt. These tube-type tires are straightforward to mount and repair, and they offer a durable compound that riders reported holds up over many trail miles while maintaining a near-new appearance.

Key Features

• Complete set: Includes an 80/100x21 front and 100/100x18 rear so you get matched handling front to back for predictable ride balance.
• Soft to intermediate compound: The rubber is formulated for traction on loose soil and sand while remaining resistant to wear for extended use.
• Aggressive deep tread: Large knobs and spacing enhance bite during acceleration, braking, and cornering on varied trail conditions.
• Tube-type design: Easy to install and repair in the field using standard tubes and patches, which is useful for trail riders.
• Durability: A tougher rubber construction helps resist abrasion and pinch damage on rough off-road terrain.

Who It's For

This tire set is aimed at recreational trail riders and amateur motocross racers who spend most of their time on soft to intermediate surfaces such as loose dirt, sand washes, loamy woods trails, and mixed hard-packed sections. It is a sensible, cost-conscious choice for riders who want predictable traction and a durable tread without specialized race compounds.

Riders who primarily compete on hard-pack, asphalt, or need tubeless setups should look elsewhere; similarly, those requiring very soft-sand specific or full-on race tires may prefer a different compound or knob arrangement tailored specifically to those conditions.
