Mickey Thompson | ET Street R | P305/45R18 | DOT street-legal drag radial | R2 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. For P305/45R18, the listed overall diameter is 29.0 in. and the tread width is 10.7 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 91.2 in. circumference is useful when comparing gearing and staggered drag setups.
