Tire 14.5/32.0R15 Radial Phoenix Drag Rear (F9)

The 14.5/32.0R15 Radial Phoenix Drag Rear Tire (F9) from PHOENIX RACE TIRES is purpose-built for serious drag racing and straight-line acceleration applications where maximum traction and consistent launch performance are non-negotiable. Whether you're running a dedicated drag radial setup on a street-legal race car or building a dedicated quarter-mile machine, this rear tire delivers the compound stiffness and sidewall construction needed to hook hard off the line. Drag-specific tires like this are engineered to resist the violent torque loads and heat cycling that come with repeated launch cycles, making them essential for competitors who demand predictable grip and minimal wheel spin under boost or nitrous.

The 32.0R15 sidewall designation indicates a radial structure optimized for drag loads, with the 14.5-inch width providing a contact patch engineered for forward bite rather than lateral cornering grip. The F9 compound is formulated to generate consistent traction temperatures across repeated passes, resisting the rubber degradation that softer street compounds suffer when exposed to launch-line forces exceeding 1.5g acceleration. Radial construction in this class provides superior load distribution compared to bias-ply alternatives, reducing sidewall flex inconsistency that would otherwise translate to variable 60-foot times. At 30.65 lbs per tire, the weight is optimized for minimal rotational inertia while maintaining structural integrity under extreme launch torque, critical for vehicles producing 500+ hp.

This rear tire excels on dedicated drag radial platforms—vehicles running 15-inch drag wheels with slicks-only racing suspension geometry. Installation requires proper wheel balance and alignment specific to drag racing (often zero or negative camber rear setups), and riders should verify that their vehicle's rear axle housing and differential are rated for the increased traction this compound delivers. The 14.5/32.0R15 size is not DOT-legal for street use and is intended exclusively for track, strip, or closed-course competition; confirm compatibility with your wheel fitment and vehicle's tire load rating before mounting. Rotate and heat-cycle tires properly between passes to maintain compound integrity and maximize the lifespan of multiple racing events.
