X-PRO 18-Inch Rear Wheel
The X-PRO 18-Inch Rear Wheel is a brand-new wheel assembly designed for dirt bikes using a disc brake system. It comes in a 110/90-18 tire size and includes a 15mm bearing assembly, which supports standard rear hub configurations found on many off-road bikes. Riders should note that this wheel is not compatible with Hawk 250 models. This wheel offers a straightforward replacement option for worn or damaged 18″ rear rims and can improve braking response and rotor alignment when paired with compatible calipers.

PIVOTRAX 18-Inch Rim Strip
PIVOTRAX Rim Strips are designed to protect inner tubes from sharp spoke nipples and prevent flats. The 2-pack uses a durable rubber compound with a standard 1″ width, making it compatible with most 18″ rims used on off-road and street motorcycles. A pre-cut valve stem hole simplifies alignment during tire changes, reducing setup time and helping maintain proper bead seating. These strips are a practical upgrade for riders who frequently ride on rough terrain or in desert conditions where spoke nipples may contact tubes.

Buying Guide
Compatibility Essentials
When choosing an 18-inch rim or rim-related accessory, verify brake compatibility (disc vs. drum), axle diameter, and bearing size. Rear wheels and some rims may require specific bearing spacings (such as 15mm) or brake rotor mounting patterns. Always confirm your bike’s hub type, rotor position, and caliper clearance to avoid misfits that could compromise braking performance or safety on rough terrain.
Rim Vs Rim Strip: What To Buy
A full wheel assembly provides a ready-to-ride replacement but may be more expensive and heavier. Rim strips, like the PIVOTRAX and TUSK options, protect inner tubes from spoke nipples and can extend tube life, especially on rough trails. Consider your riding style and maintenance routine: if you frequently ride on rocks or washboard surfaces, investing in protective rim strips is a practical way to reduce flats and downtime.
Size, Fit, And Application
18″ rims come in different widths and tire profiles. A 110/90-18 tire size, for example, is common on dirt bikes but ensure your rim width supports the tire bead and riding style. The presence of a 15mm bearing or other hub-specific components can also influence compatibility. When mixing rims, tires, and tubes, verify the entire assembly’s fit with the frame and swingarm clearance to prevent rubbing during heavy acceleration or cornering.
Material, Durability, And Weight
Rim strips use rubber compounds designed for abrasion resistance, while full rims may employ alloy or steel construction. Durable rim strips reduce flats, but full rims provide structural rigidity and a more predictable ride. For riders who frequently jump or land hard, choosing a robust rim with proven durability is essential to maintain wheel integrity after impacts.
Installation Tips And Maintenance
Follow manufacturer guidelines for torque settings, bearing seating, and rotor alignment. Properly mounting rim strips requires careful bead seating and valve alignment to prevent leaks. Regular inspection for wear, cuts in rim tape, and spoke nipple condition helps catch issues before they lead to tube failures on the trail. Keeping a lightweight patch kit and spare rim tape on hand is prudent for longer trips.
Brand Support And Compatibility Checks
With aftermarket rims and strips, brand support varies. Some products offer straightforward compatibility with common 18″ dirt bike hubs, while others require careful matching of width, stripe thickness, and bead seat diameter. When possible, consult product manuals or community feedback for your bike model to confirm long-term reliability and ease of replacement parts availability.
