For many dual-sport enthusiasts, the industry standard for rear wheel sizing has long been the 18-inch rim. This configuration is widely considered the gold standard for off-road performance, primarily because it allows for a taller tire sidewall. A taller sidewall provides better bump absorption, increased rim protection against rock strikes, and the ability to run lower tire pressures for enhanced traction in loose terrain. However, as motorcycle manufacturers evolve their designs—particularly with modern scramblers and adventure-oriented cruisers—we are seeing an increase in 19-inch rear wheel setups. This shift often leaves riders searching for a 19-inch rear dual sport tire, a request that can feel like hunting for a needle in a haystack.

The Reality of the 19-Inch Rear
If your motorcycle specifies a 19-inch rear wheel, you are likely navigating a niche segment of the market. Most high-performance dual-sport tires are engineered for 18-inch rear wheels. When you search for a 19-inch rear, you often find options that lean heavily toward either pure street performance or, conversely, tires designed for flat-track racing. However, the market is not entirely devoid of options. Several manufacturers recognize the growing need for dual-purpose rubber that fits these unique rim diameters.
Key Considerations for 19-Inch Rear Tires
- Sidewall Profile: Because a 19-inch rim is larger than an 18-inch rim, the available space for the tire’s sidewall is reduced. This results in a “lower profile” tire, which can make the ride feel stiffer and potentially more susceptible to rim damage during aggressive off-road use.
- Tread Pattern Versatility: Many 19-inch tires are marketed as “scrambler” tires. These are excellent for light gravel, fire roads, and pavement, but they may lack the deep, aggressive knobs required for deep mud or steep, technical single-track riding.
- Load Rating and Compatibility: Always verify that the tire’s load and speed rating matches or exceeds the requirements set by your motorcycle’s manufacturer.
Notable Options and Alternatives
While dedicated knobby dual-sport tires for 19-inch rears remain limited, riders often look toward Pirelli MT-60 or similar scrambler-style rubber. These tires offer a balanced tread pattern that performs reliably on asphalt while providing enough grip for light off-road exploration. Another avenue is exploring tires designed for front-wheel applications that share the same dimensions, though this requires careful consultation with a tire professional to ensure the directional tread and structural integrity are appropriate for the increased torque and braking forces applied to a rear wheel.
Should You Swap to an 18-Inch Rim?
Many riders eventually ask: Is there any real reason not to swap to an 18-inch rear wheel? The answer depends on your goals. If you plan on doing serious, technical off-road riding, the move to an 18-inch rim is highly recommended. It opens up a massive catalog of high-performance knobby tires that are specifically built for abuse. However, if your bike is intended for light adventure touring, gravel roads, and commuting, the 19-inch rear is perfectly capable and often provides better stability at highway speeds.
