31.0/13.0-15 ET Drag Tire

The Mickey Thompson 31.0/13.0-15 ET Drag Tire is purpose-built for dedicated drag racing applications where extreme launch grip and consistent quarter-mile performance are non-negotiable. This 31-inch diameter, 13-inch width bias-ply slick delivers the traction needed for straight-line acceleration on prepped surfaces, making it the choice for bracket racers, street-legal drag competitors, and serious weekend warriors who demand consistent ET performance. The white letter sidewall adds authentic drag tire aesthetics while the M5 compound formulation is engineered specifically for the heat cycles and loading conditions unique to drag racing.

The bias-ply construction delivers superior sidewall stiffness compared to radial alternatives, which is critical for maintaining consistent tire growth and load transfer during hard launch. The M5 compound strikes a balance between grip and durability, providing edge grip while resisting excessive wear during repeated acceleration runs. At 33.54 lbs per tire, this is a genuine drag-specific tire, not a street compromiser—the weight and construction contribute to predictable response and minimal deflection under the extreme forces of hard launches. The 15-inch bead diameter fits classic drag wheel fitments common to purpose-built racers and vintage muscle cars, while the 13.0-inch width is narrow enough to minimize sidewall roll yet wide enough to maximize launch contact patch.

This tire is ideal for bracket racers, heads-up competitors, and street-legal drag entries running 15-inch wheel packages—particularly vehicles with factory or custom drag-oriented suspensions. Installation requires proper wheel and brake compatibility verification; confirm your wheel hub bore, offset, and lug pattern match before purchase. These tires are not street-legal in most jurisdictions due to their specialized compound and lack of tread; use exclusively on closed courses or designated drag strips. Pair with quality drag radials or slicks on the rear axle for maximum traction, and consult your suspension tuner regarding tire pressure and sidewall stiffness for your specific vehicle weight and power level.
