Mickey Thompson | ET Street S/S | P305/45R20 | street-to-strip drag radial | R2 compound | Sold individually
The ET Street S/S is built for drivers who want a high-performance street tire that can also make passes at the strip. Its radial construction, R2 compound and redistributed tread void balance dry launch contact with more wet-road consideration than a minimal-void race pattern. For P305/45R20, the listed overall diameter is 31.1 in. and the tread width is 10.3 in.; these measured figures help compare fender clearance and the actual working tread. It is approved for 9.5–11.5 in. wheel widths and a 10.0 in. measuring rim. Its listed 97.6 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.
