Mickey Thompson | ET Street R | 32X17.50-15LT | DOT street-legal drag bias-ply tire | M5 compound | Sold individually
The ET Street R puts dry launch traction first for drivers who also need a DOT-approved tire for street use. Its minimal tread void emphasizes rubber-to-road contact, and the exact dimensions and compound matter when choosing a rear tire for a drag-oriented build. This size uses bias-ply construction; the radial ET Street R sizes require different setup considerations. For 32X17.50-15LT, the listed overall diameter is 32.2 in. and the tread width is 14.4 in.; these measured figures help compare fender clearance and the actual working tread. The source lists 12.0–15.0 in. wheel widths and a 14.0 in. measuring rim. Its listed 101.2 in. circumference is useful when comparing gearing and staggered drag setups.

Drag compounds and reduced tread void call for care in wet conditions; verify the vehicle’s requirements before street use. A stamped maximum pressure is not a recommended everyday inflation setting.
