Mickey Thompson 321051004 Sportsman S/R 26X6.00R18LT 79H Front Drag Radial Tire

The Mickey Thompson 321051004 Sportsman S/R is a 26X6.00R18LT front drag radial built specifically for staggered hot rod and muscle car setups that run wide rear drag tires on 18-inch wheels. Part of Mickey Thompson's iconic Sportsman S/R lineup, the 321051004 features a directional "Flamed" tread pattern with radial construction that delivers improved wet traction, a smooth highway ride, and H-speed rating up to 130 mph. Sold individually, the 321051004 is engineered to pair directly with Mickey Thompson ET Street Radial rear tires, giving classic street rods, restomods, and modern muscle cars the cleanest staggered front-to-rear stance available in a DOT-approved radial.

Why the Mickey Thompson 321051004 Stands Apart

Most skinny front tire options for performance vehicles are either bias-ply racing tires with no street manners or stretched passenger tires that look out of place. The 321051004 Sportsman S/R was designed from the ground up as a matching front tire for the Sportsman S/R rear lineup. The Flamed tread pattern carries across both front and rear tires, so a staggered setup looks intentional and period-correct rather than mismatched. Radial construction keeps the footprint consistent under load, and the H-rated speed certification means the 321051004 is fully street-legal at highway speeds. A 26-inch overall diameter makes this tire a natural fit for an 18x5 wheel on the front of a late-model or classic muscle build.

Sportsman S/R Flamed Tread Design

The Sportsman S/R Flamed tread is the defining visual element of the 321051004. The directional pattern evacuates water efficiently in wet conditions and maintains grip at the edge of the contact patch. The low-profile sidewall keeps the tire's look aggressive and period-correct without the excessive sidewall flex that affects steering response. With a 5.7-inch tread width on a measured 5.0-inch rim, the 321051004 fills a front wheel well cleanly without tucking or rubbing on standard hot rod front suspensions.

Fitment and Application

The 321051004 is a universal front performance tire sold individually. It is designed for use on 18-inch wheels with a rim width between 4.5 and 5.5 inches (measured width 5.0 inches). The 26-inch overall diameter makes it ideal as a skinny front tire paired with wider rear tires on street rods, muscle cars, restomods, and performance builds. It is not vehicle-specific and is not rated for rear drive use on high-horsepower drag applications. Confirm your front wheel width before ordering.
